6.1 Clinical Trials Experience
Because clinical trials and other studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Common adverse reactions were: ulcerative stomatitis, leukopenia, nausea, and abdominal distress. Other clinically relevant adverse reactions were infection, malaise, fatigue, chills, fever, and dizziness.
The most common adverse reactions of methotrexate that exceeded the rate of placebo in 12- to 18-week double-blind studies in patients (n=128) with rheumatoid arthritis are listed below. Patients received methotrexate 7.5 to 15 mg orally once weekly. Most patients received concomitant nonsteroidal anti-inflammatory drugs (NSAIDs) and some also received corticosteroids. Hepatic histology was not examined in these short-term studies.
Incidence ≥10%: Elevated liver tests 15%, nausea/vomiting 10%
Incidence 3% to <10%: Stomatitis, thrombocytopenia (platelet count < 100,000/mm 3 )
Incidence 1% to <3%: Rash/pruritus/dermatitis, diarrhea, alopecia, leukopenia (white blood cell count < 3000/mm 3 ), pancytopenia, dizziness
Two other controlled trials of patients (n=680) with rheumatoid arthritis who received methotrexate 7.5 mg to 15 mg orally once weekly showed the following serious adverse reaction:
Incidence 1%: Interstitial pneumonitis
Other less common adverse reactions were: anemia, headache, upper respiratory infection, anorexia, arthralgias, chest pain, coughing, dysuria, eye discomfort, epistaxis, fever, infection, sweating, tinnitus, vaginal discharge.
Polyarticular Juvenile Idiopathic Arthritis (pJIA)
The most common adverse reactions reported in patients 2 to 18 years of age with pJIA treated with methotrexate 5 mg/m 2 to 20 mg/m 2 orally once weekly or 0.1 to 0.65 mg/kg orally once weekly were as follows: elevated liver tests 14%; gastrointestinal reactions (e.g., nausea, vomiting, diarrhea) 11%; stomatitis 2%; leukopenia 2%; headache 1.2%; alopecia 0.5%; dizziness 0.2%; rash 0.2%. Most patients received concomitant NSAIDs and some also received corticosteroids.
In two published series of adults with psoriasis (n=204, 248) who received methotrexate up to 25 mg per week for up to 4 years, adverse reaction rates were similar to those in patients with rheumatoid arthritis, except for alopecia, photosensitivity, and “burning of skin lesions” (3% to 10% each). Painful plaque erosions have been reported.
6.2 Postmarketing Experience
The following adverse reactions have been identified during postapproval use of methotrexate. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Cardiovascular: Thromboembolic events (including arterial thrombosis, cerebral thrombosis, deep vein thrombosis, retinal vein thrombosis, thrombophlebitis, and pulmonary embolus), pericarditis, pericardial effusion, hypotension, sudden death
Eye: Optic neuropathy, blurred vision, ocular pain, conjunctivitis, xerophthalmia
Gastrointestinal: Hemorrhagic enteritis, intestinal perforation, gingivitis, pancreatitis, pharyngitis, hematemesis, melena, gastrointestinal ulceration
Hematology: Aplastic anemia, lymphadenopathy, hypogammaglobulinemia
Hepatobiliary: Acute hepatitis, decreased serum albumin, fibrosis, cirrhosis
Immune system: Anaphylaxis, anaphylactoid reactions, vasculitis
Musculoskeletal: Stress fracture, soft tissue and bone necrosis, arthralgia, myalgia, osteoporosis
Nervous system: Headaches, drowsiness, blurred vision, speech impairment (including dysarthria and aphasia), transient cognitive dysfunction, mood alteration, unusual cranial sensations, paresis, encephalopathy, and convulsions.
Renal: Azotemia, hematuria, proteinuria, cystitis
Reproductive: Defective oogenesis or spermatogenesis, loss of libido, impotence, gynecomastia, menstrual dysfunction
Respiratory: Pulmonary fibrosis, respiratory failure, chronic interstitial obstructive pulmonary disease, pleuritic pain and thickening, alveolitis

7 DRUG INTERACTIONS
7.1 Effects of Other Drugs on Methotrexate
Drugs that Increase Methotrexate Exposure
Coadministration of methotrexate with the following products may increase methotrexate plasma concentrations, which may increase the risk of methotrexate severe adverse reactions. In some cases, the coadministration of methotrexate with these products may also subsequently reduce active metabolite formation, which may decrease the clinical effectiveness of methotrexate. Increased organ specific adverse reactions may also occur when methotrexate is coadministered with hepatotoxic or nephrotoxic products.
If coadministration cannot be avoided, monitor closely for methotrexate adverse reactions when coadministered with:
- Oral antibiotics (including neomycin)
- Oral or intravenous penicillin or
- Highly protein-bound drugs
(e.g., oral anticoagulants, phenytoin,
salicylates, sulfonamides, sulfonylureas,
- Antifolate drugs (e.g., dapsone, pemetrexed, pyrimethamine and sulfonamides)
- Aspirin and other nonsteroidal
- Hepatotoxic products
- Proton pump inhibitors
- Weak acids (e.g., salicylates)
- Nephrotoxic products
Coadministration of methotrexate with nitrous oxide anesthesia potentiates the effect of methotrexate on folate-dependent metabolic pathways, which may increase the risk of severe methotrexate adverse reactions. Avoid nitrous oxide anesthesia in patients receiving methotrexate. Consider alternative therapies in patients who have received prior nitrous oxide anesthesia.
Coadministration of methotrexate with folic acid or its derivatives decreases the clinical effectiveness of methotrexate in patients with neoplastic diseases. Methotrexate competes with reduced folates for active transport across cell membranes. Instruct patients to take folic or folinic acid only as directed by their healthcare provider [see Warnings and Precautions (5.10)].
8 USE IN SPECIFIC POPULATIONS
Methotrexate Tablets are contraindicated in pregnant women with non-neoplastic diseases [see Contraindications ( 4)].
Based on published reports and its mechanism of action [see Clinical Pharmacology ( 12.1)] , methotrexate can cause embryo-fetal toxicity and fetal death when administered to a pregnant woman. There are no animal data that meet current standards for nonclinical developmental toxicity studies. Advise pregnant women with neoplastic diseases of the potential risk to a fetus.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Published data from case reports, literature reviews, and observational studies report that methotrexate exposure during pregnancy is associated with an increased risk of embryo-fetal toxicity and fetal death. Methotrexate exposure during the first trimester of pregnancy is associated with an increased incidence of spontaneous abortions and multiple adverse developmental outcomes, including skull anomalies, facial dysmorphism, central nervous system abnormalities, limb abnormalities, and sometimes cardiac anomalies and intellectual impairment. Adverse outcomes associated with exposure during second and third trimesters of pregnancy include intrauterine growth restriction and functional abnormalities. Because methotrexate is widely distributed and persists in the body for a prolonged period, there is a potential risk to the fetus from preconception methotrexate exposure.
A prospective multicenter study evaluated pregnancy outcomes in women taking methotrexate less than or equal to 30 mg/week after conception. The rate of spontaneous abortion and miscarriage in pregnant women exposed to methotrexate was 42% (95% confidence interval [95% CI] 29, 59), which was higher than in unexposed patients with autoimmune disease (22%; 95% CI: 17, 30) and unexposed patients with nonautoimmune disease (17%; 95% CI: 13, 23). Of the live births, the rate of major birth defects in pregnant women exposed to methotrexate after conception was higher than in unexposed patients with autoimmune disease (adjusted odds ratio (OR) 1.8 [95% CI: 0.6, 6]) and unexposed patients with non-autoimmune disease (adjusted OR 3.1 [95% CI: 1, 10]) (2.9%). Major birth defects associated with pregnancies exposed to methotrexate after conception were not always consistent with methotrexate-associated adverse developmental outcomes.
Limited published literature report the presence of methotrexate in human milk in low amounts, with the highest breast milk to plasma concentration ratio reported to be 0.08:1. There are no data on the effects of methotrexate or its metabolites on the breastfed child or their effects on milk production. Because of the potential for serious adverse reactions in a breastfed child, instruct women not to breastfeed during treatment with Methotrexate Tablets and for 1 week after the final dose.
8.3 Females and Males of Reproductive Potential
Methotrexate can cause malformations and fetal death at doses less than or equal to the recommended clinical doses [Use in Specific Populations ( 8.1)].
Advise females of reproductive potential to use effective contraception during treatment with Methotrexate Tablets and for 6 months after the final dose.
Methotrexate can cause chromosomal damage to sperm cells. Advise males with female partners of reproductive potential to use effective contraception during treatment with Methotrexate Tablets and for 3 months after the final dose.
Based on published reports of female infertility after methotrexate, advise females of reproductive potential that methotrexate can cause impairment of fertility and menstrual dysfunction during treatment with Methotrexate Tablets and after the final dose. It is not known if the infertility may be reversed in all affected females.
Based on published reports of male infertility after methotrexate, advise males that methotrexate can cause oligospermia or infertility during treatment with Methotrexate Tablets and after the final dose. It is not known if the infertility may be reversed in all affected males.
8.4 Pediatric Use
The safety and effectiveness of Methotrexate Tablets in pediatric patients have been established for the treatment of ALL as part of the combination chemotherapy maintenance regimen and the treatment of pJIA [see Indications and Usage ( 1), Dosage and Administration ( 2)] . No new safety signals have been observed in pediatric patients in clinical studies [see Adverse Reactions ( 6.1)].
The safety and effectiveness of Methotrexate Tablets have not been established in pediatric patients for the other indications [see Indications and Usage ( 1)].
8.5 Geriatric Use
Clinical studies of methotrexate did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.
8.6 Renal Impairment
Methotrexate elimination is reduced in patients with renal impairment [see Clinical Pharmacology ( 12.3)] . Patients with renal impairment are at increased risk for methotrexate adverse reactions. Closely monitor patients with renal impairment [creatinine clearance (CLcr) less than 90 mL/min, Cockcroft-Gault] for adverse reactions. Reduce the dosage or discontinue Methotrexate Tablets as appropriate [see Warnings and Precautions ( 5.8)].
8.7 Hepatic Impairment
The pharmacokinetics and safety of methotrexate in patients with hepatic impairment is unknown. Patients with hepatic impairment may be at increased risk for methotrexate adverse reactions based on the elimination characteristics of methotrexate [see Clinical Pharmacology ( 12.3)]. Closely monitor patients with hepatic impairment for adverse reactions. Reduce the dosage or discontinue Methotrexate Tablets as appropriate [see Warnings and Precautions ( 5.5)].
Overdosage, including fatal overdosage, has occurred with methotrexate [see Warnings and Precautions ( 5. 9)].
Manifestations of methotrexate overdosage include adverse reactions reported at pharmacologic doses, particularly hematologic and gastrointestinal reactions (e.g., leukopenia, thrombocytopenia, anemia, pancytopenia, myelosuppression, mucositis, stomatitis, oral ulceration, nausea, vomiting, gastrointestinal ulceration, or gastrointestinal bleeding). In some cases, no symptoms were reported; however, sepsis or septic shock, renal failure, and aplastic anemia were also reported.
Leucovorin and levoleucovorin are indicated for diminishing the methotrexate adverse reactions of methotrexate overdosage. Administer leucovorin or levoleucovorin as soon as possible after methotrexate overdosage). Monitor serum creatinine and methotrexate levels to guide leucovorin or levoleucovorin therapy. Refer to the leucovorin or levoleucovorin prescribing information for additional dosage information.
Glucarpidase is indicated for the treatment of toxic plasma methotrexate concentrations (>1 micromole per liter) in patients with delayed methotrexate clearance due to impaired renal function. Refer to the glucarpidase prescribing information for additional dosage information.
Administer concomitant hydration and urinary alkalinization.
Neither hemodialysis nor peritoneal dialysis has been shown to improve methotrexate elimination; however, methotrexate has been effectively cleared with acute, intermittent hemodialysis using a high-flux dialyzer.
Methotrexate is dihydrofolate reductase inhibitor with the chemical name of N-[4-[[(2,4 diamino-6-pteridinyl) methyl]methylamino]benzoyl]-L-glutamic acid. The molecular formula is C 20H 22N 8O 5 and the molecular weight is 454.45 g/mol. The structural formula is:
Methotrexate Tablets, USP for oral administration are available as 2.5 mg tablets. Each methotrexate tablet, USP contains 2.5 mg methotrexate equivalent to 2.74 mg methotrexate sodium and the following inactive ingredients: lactose (anhydrous), magnesium stearate, pregelatinized starch, sodium hydroxide pellets, sodium starch glycolate and purified water.
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Methotrexate inhibits dihydrofolic acid reductase. Dihydrofolates must be reduced to tetrahydrofolates by this enzyme before they can be utilized as carriers of one-carbon groups in the synthesis of purine nucleotides and thymidylate. Therefore, methotrexate interferes with DNA synthesis, repair, and cellular replication. Actively proliferating tissues such as malignant cells, bone marrow, fetal cells, buccal and intestinal mucosa, and cells of the urinary bladder are in general more sensitive to this effect of methotrexate.
The mechanism of action in rheumatoid arthritis and in psoriasis is unknown.
At doses of 30 mg/m 2 or less, the mean bioavailability is approximately 60%. Peak plasma concentrations are reached within 0.75 to 6 hours following oral administration. Methotrexate may undergo enterohepatic recirculation; however, this pathway has not been fully characterized.
Effect of Food
Food has been shown to delay absorption and reduce peak concentration.
Methotrexate in serum is approximately 50% protein bound.
Methotrexate does not penetrate the blood-cerebrospinal fluid barrier at concentrations achieved with the recommended dosages.
The elimination half-life of methotrexate is approximately 3 to 10 hours.
Small amounts of methotrexate polyglutamates may remain in tissues for extended periods. The retention and prolonged drug action of these active metabolites vary among different cells, tissues, and tumors.
Nonlinear elimination due to saturation of renal tubular reabsorption has been observed in studies of patients with psoriasis receiving methotrexate doses between 7.5 mg and 30 mg.
Methotrexate is partially metabolized by intestinal flora after oral administration.
Methotrexate primarily undergoes hepatic and intracellular metabolism to active polyglutamated forms which can be converted back to methotrexate by hydrolase enzymes. Methotrexate also undergoes minor metabolism to active 7-hydroxymethotrexate.
Methotrexate primarily undergoes renal excretion by glomerular filtration and active tubular secretion that is dependent upon dosage and route of administration.
Biliary excretion accounts for ≤10% of the methotrexate dose.
The effect of hepatic impairment on the pharmacokinetics of methotrexate is unknown.
In pediatric patients with leukemia, oral absorption (23% to 95%) of methotrexate is variable and dose-dependent. The difference between highest and lowest peak methotrexate concentrations (C max 0.11 to 2.3 micromolar after a 20 mg/m 2 dose) was 20-fold. The time to peak concentration (T max 0.67 to 4 hours after a 15 mg/m 2 dose) and fraction of dose absorbed is variable. The absorption of doses greater than 40 mg/m 2 is significantly less than that of lower doses.
In pediatric patients with pJIA, plasma concentrations of methotrexate are variable. Following oral administration of methotrexate 6.4 mg/m 2/week to 11.2 mg/m 2/week, mean serum concentrations were 0.59 micromolar (0.03 to 1.40) at 1 hour, 0.44 micromolar (0.01 to 1.00) at 2 hours, and 0.29 micromolar (0.06 to 0.58) at 3 hours.
In pediatric patients receiving methotrexate for acute lymphoblastic leukemia (6.3 mg/m 2 to 30 mg/m 2) or for JIA (3.75 mg/m 2 to 26.2 mg/m 2), the terminal half-life has been reported to range from 0.7 to 5.8 hours or from 0.9 to 2.3 hours, respectively.
Patients with Renal Impairment
The elimination half-life of methotrexate is variable and increases with the severity of renal impairment.

PATIENT PACKAGE INSERT
Methotrexate (meth oh trex ate)
What is the most important information I should know about Methotrexate?
Methotrexate can cause serious side effects that may be severe and lead to death, including:
Harm to an unborn baby, including birth defects or death of an unborn baby.
Females who can become pregnant:
- Your healthcare provider should do a pregnancy test before you start taking Methotrexate to see if you are pregnant.
- If you are being treated for a medical condition other than cancer, do not take Methotrexate if you are pregnant. See “Who should not take Methotrexate?”
- If you are taking Methotrexate to treat your cancer, you and your healthcare provider will decide if you will take Methotrexate if you are pregnant.
- Use effective birth control (contraception) during treatment and for 6 months after your final dose of Methotrexate. Ask your healthcare provider what forms of birth control you can use during this time.
- Tell your healthcare provider right away if you become pregnant or think you are pregnant during treatment with Methotrexate.
Males with female partners who are able to become pregnant:
- Use effective birth control during treatment and for 3 months after your final dose of Methotrexate.
- Tell your healthcare provider right away if your female partner becomes pregnant during treatment with Methotrexate.
Severe allergic reactions. Severe allergic reactions can happen with Methotrexate. Signs and symptoms of a severe allergic reaction may include:
- skin rash, itching and hives
- swelling of the face, lips, tongue, or throat
- trouble breathing
- fast heart rate
- feeling faint
- stomach-area pain
- vomiting or diarrhea
Do not take Methotrexate if you have had a severe allergic reaction to Methotrexate in the past.
Get medical help right away if you develop any of the signs or symptoms of a severe allergic reaction listed above. Decreased blood cell counts. Methotrexate can affect your bone marrow and cause decreases in red blood counts,
white blood cell counts, and platelets that can be severe and life-threatening
- Your healthcare provider will check your blood cell counts when you start and during treatment with Methotrexate.
Call your healthcare provider right away if you develop any of the following:
- a new fever
- symptoms of infection
- easy bruising or bleeding that will not stop (persistent bleeding)
Severe stomach and intestine problems (gastrointestinal) problems.
- Diarrhea, vomiting, nausea, and mouth sores can happen in people who take Methotrexate.
- Inflammation of the intestine with severe bleeding and a tear in the intestinal wall (perforation) have happened with Methotrexate and cause death.
- People who have stomach ulcers (peptic ulcer disease) or ulcerative colitis (UC) have a greater risk of developing severe stomach or intestine problems with Methotrexate.

See “What are the possible side effects of Methotrexate” for more information about side effects.
What is Methotrexate?
Methotrexate is a prescription medicine used:
- in combination with other chemotherapy medicines in adults and children, for maintenance treatment of acute lymphoblastic leukemia (ALL)
- to treat adults with mycosis fungoides (cutaneous T-cell lymphoma)
- in combination with other therapies to treat adults with non-Hodgkin lymphoma that has come back (relapsed) or did not respond to previous treatment (refractory)
- to treat adults with rheumatoid arthritis
- to treat children with polyarticular juvenile idiopathic arthritis (pJIA)
- to treat adults with severe psoriasis
- It is not known if Methotrexate is safe and effective in treating children with any disease other than ALL as part of a combination regimen used for maintenance therapy of their cancer, and for the treatment of pJIA.
- It is not known if Methotrexate is safe in people with liver problems.
Do not take Methotrexate if you:
- are pregnant and are being treated or will be treated with Methotrexate for rheumatoid arthritis, pJIA, or severe psoriasis or for any disease other than cancer). Methotrexate can cause harm to an unborn baby, including birth defects or death of an unborn baby. See “What is the most important information I should know about Methotrexate?”
- have or had a severe allergic reaction to Methotrexate in the past. See “ What is the most important information I should know about Methotrexate?” See the end of this leaflet for a complete list of ingredients in Methotrexate.
Before taking Methotrexate tell your healthcare provider about all of your medical conditions, including if you:
- have problems swallowing tablets
- have kidney problems or are receiving dialysis treatments
- have liver problems
- drink alcohol-containing beverages and, during treatment with Methotrexate, if there are any changes in the amount of alcoholic beverages you drink
- have fluid in your stomach-area (ascites)
- have lung problems or fluid in your lungs (pleural effusion)
- plan to have any surgeries with general anesthesia, including dental surgery
- have stomach ulcers (peptic ulcer disease)
- have ulcerative colitis
- have recently received or are scheduled to receive a vaccine. You should not receive live vaccines during treatment with Methotrexate.
- are breastfeeding or plan to breastfeed. Methotrexate may pass into your breast milk. Do not breastfeed during treatment and for 1 week after your last dose of Methotrexate.
Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins and herbal supplements. Methotrexate and certain other medicines can affect each other and cause serious side effects. Do not start or change any medicines unless you have talked to your doctor and your doctor has told you it is safe. Know all the medicines that you take and keep a list of them with you at all times to show doctors and pharmacists.
How should I take Methotrexate?
- Take Methotrexate exactly as prescribed by your healthcare provider. Your dose of Methotrexate and when you take it will depend on the condition that is being treated.
- Do not take more Methotrexate than prescribed. Do not change your dose of Methotrexate unless your healthcare provider tells you to.
- Taking more Methotrexate than prescribed or taking Methotrexate more often than prescribed, can lead to severe side effects and cause death.
- If you take too much Methotrexate call your healthcare provider or go to your nearest hospital emergency room right away. You will need to receive a medicine as soon as possible to help reduce side effects that could be severe and could cause death.
- If you miss taking a dose of Methotrexate, call your healthcare provider for instructions about when to take your next dose of Methotrexate.
If you are taking Methotrexate for treatment of severe psoriasis, rheumatoid arthritis, or polyarticular juvenile idiopathic arthritis:
- Take your Methotrexate dose 1 time each week, not every day. Severe side effects and death have happened in people who mistakenly have taken Methotrexate every day instead of 1 time each week.
- Take a folic acid or folinic acid supplement every day during treatment with Methotrexate, as instructed by your healthcare provider, to help reduce the chance of developing certain side effects, such as mouth sores.
If you are taking Methotrexate to treat your cancer:
- Follow your healthcare provider’s instructions about how much Methotrexate to take and when to take it.
- Do not take folic acid or folinic acid during treatment with Methotrexate unless your healthcare provider tells you to. Taking folic acid or folinic acid with Methotrexate may make your Methotrexate treatment less effective.
What are the possible side effects of Methotrexate?
Methotrexate can cause serious side effects that may be severe and lead to death including:
- See “ What is the most important information I should know about Methotrexate?”
- Serious infections. People who take Methotrexate have an increased risk of developing infections that can be life-threatening or cause death. These infections may include: bacterial, fungal, or viral infections, including Pneumocystis jiroveci pneumonia, invasive fungal infections, hepatitis B infection that comes back (reactivation), tuberculosis infection that may be new or reactivation, and Herpes zoster or cytomegalovirus (CMV) that spreads throughout the body (disseminated).
- Tell your healthcare provider right away if you develop a new fever or if you have any symptoms of infection during treatment with Methotrexate.
- Brain and spinal cord (nervous system) problems. Methotrexate can cause nervous system problems that can be severe and last for a short time or last for a long time. These nervous system problems can get progressively worse, may not get better (irreversible), and can cause death. The risk for a certain nervous system problem called leukoencephalopathy is increased in people who have had radiation treatment to their head (cranial radiation) in the past.
- Tell your healthcare provider about any new nervous system symptoms that you develop during treatment with Methotrexate.
Secondary cancers. Secondary (new) cancers can happen in people who take Methotrexate.
- In people with psoriasis, the risk of new skin cancers is increased with Methotrexate and further increased if you take the medicine cyclosporine after receiving treatment with Methotrexate.
- Certain blood cancers can happen during treatment with Methotrexate. In some cases, these blood cancers may completely go away (regress completely) after Methotrexate is stopped.
- Tumor lysis syndrome (TLS). TLS is caused by the fast breakdown of cancer cells. TLS can cause kidney failure and the need for dialysis treatment, abnormal heart rhythm, seizure, and sometimes death. Your healthcare provider may do blood tests to check you for TLS if you are receiving Methotrexate as a cancer treatment.
- Possible fertility problems (infertility) in males and females. Methotrexate can cause fertility problems in males and females, and can cause sperm production to stop in males, and menstrual problems in females. Males may not be able to father a child. Females may not be able to become pregnant. It is not known if your fertility may return. Talk with your healthcare provider about your risk for infertility if this is a concern for you.
