Label: PROGESTERONE injection

Progesterone injection, USP, a progestin, is a sterile solution of progesterone in a suitable vegetable oil available for intramuscular use.

Progesterone occurs as a white or creamy white, crystalline powder. It is odorless and is stable in air. Practically insoluble in water, it is soluble in alcohol, acetone, and dioxane and sparingly soluble in vegetable oils.

It has the following structural formula:

C21H30O2           M.W. 314.47

Pregn-4-ene-3, 20-dione

Each mL contains: Progesterone 50 mg, Benzyl Alcohol 10% as preservative in Sesame Oil q.s.

Transforms proliferative endometrium into secretory endometrium.

Inhibits (at the usual dose range) the secretion of pituitary gonadotropins, which in turn prevents follicular maturation and ovulation.

This drug is indicated in amenorrhea and abnormal uterine bleeding due to hormonal imbalance in the absence of organic pathology, such as submucous fibroids or uterine cancer.

• Current or past history of thrombophlebitis, thromboembolic disorders, or cerebral apoplexy.

• Liver dysfunction or disease.

• Known or suspected malignancy of breast or genital organs.

• Undiagnosed vaginal bleeding.

• Missed abortion.

• Known sensitivity to progesterone injection.

• Known sensitivity to sesame oil/seeds.

The physician should be alert to the earliest manifestations of thrombotic disorders (thrombophlebitis, cerebrovascular disorders, pulmonary embolism, and retinal thrombosis). Should any of these occur or be suspected, the drug should be discontinued immediately.

Medication should be discontinued pending examination if there is a sudden partial or complete loss of vision, or if there is a sudden onset of proptosis, diplopia or migraine. If examination reveals papilledema or retinal vascular lesions, medication should be withdrawn.

Acute eosinophilic pneumonia has been reported in patients receiving progesterone in sesame oil. In reported cases associated with progesterone in sesame oil, patients developed fever, dyspnea with hypoxic respiratory insufficiency, and diffuse pulmonary infiltrates. In general, patients developed eosinophilic pneumonia 2 to 4 weeks after starting progesterone in sesame oil and improved when progesterone in sesame oil was discontinued and a different formulation of progesterone and/or steroid therapy was initiated. Patients who develop these signs and symptoms while receiving progesterone in sesame oil should undergo prompt medical evaluation, and progesterone in sesame oil should be discontinued immediately.

Breakthrough bleeding; spotting; change in menstrual flow; amenorrhea; edema; change in weight (increase or decrease); changes in cervical erosion and cervical secretions; cholestatic jaundice; breast tenderness and galactorrhea; pain, irritation, and/or redness at the injection area; skin sensitivity reactions consisting of urticaria, pruritus, edema and generalized rash; acne, alopecia and hirsutism; rash (allergic) with and without pruritus; anaphylactoid reactions (including eosinophilic pneumonia); mental depression; pyrexia; insomnia; nausea; and somnolence.

A statistically significant association has been demonstrated between use of estrogen-progestin combination drugs and pulmonary embolism and cerebral thrombosis and embolism. For this reason patients on progestin therapy should be carefully observed.

There is also evidence suggestive of an association with neuro-ocular lesions, e.g., retinal thrombosis and optic neuritis.

The following adverse reactions have been observed in patients receiving estrogen-progestin combination drugs: rise in blood pressure in susceptible individual, premenstrual syndrome, changes in libido, changes in appetite, cystitis-like syndrome, headache, nervousness, fatigue, backache, hirsutism, loss of scalp hair, erythema multiforme, erythema nodosum, hemorrhagic eruption, itching, and dizziness.

The following laboratory results may be altered by the use of estrogen-progestin combination drugs: increased sulfobromophthalein retention and other hepatic function tests; coagulation tests: increase in prothrombin factors VII, VIII, IX, and X; metyrapone test; pregnanediol determinations; thyroid function: increase in PBI, and butanol extractable protein bound iodine and decrease in T3 uptake values.

Progesterone Injection, USP is administered by intramuscular injection. It differs from other commonly used steroids in that it is irritating at the place of injection.

Amenorrhea: Five to 10 mg are given for six to eight consecutive days. If there has been sufficient ovarian activity to produce a proliferative endometrium, one can expect withdrawal bleeding forty-eight to seventy-two hours after the last injection. This may be followed by spontaneous normal cycles.

Functional Uterine Bleeding: Five to 10 mg are given daily for six doses. Bleeding may be expected to cease within six days. When estrogen is given as well, the administration of progesterone is begun after two weeks of estrogen therapy. If menstrual flow begins during the course of injections of progesterone, they are discontinued.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever the solution and container permit.

Progesterone Injection, USP, 50 mg/mL is available in 10 mL multiple dose vials, individually boxed.

FOR THE TREATMENT OF AMENORRHEA (ABSENCE OF MENSES IN WOMEN WHO HAVE PREVIOUSLY HAD A MENSTRUAL PERIOD) OR ABNORMAL UTERINE BLEEDING DUE TO HORMONAL IMBALANCE.

Please read this information carefully before you start to use progesterone injection and each time your prescription is renewed, in case anything has changed. This leaflet does not take the place of discussions with your doctor. If you still have any questions, ask your doctor or healthcare provider.

About progesterone injection
Progesterone injection is a sterile injectable solution containing the natural female hormone called progesterone. Progesterone injection is indicated for the treatment of amenorrhea and abnormal uterine bleeding due to progesterone deficiency.

Understanding the role of progesterone injection in the treatment of your menstrual irregularities.
Progesterone is one of the hormones essential for regular menstrual periods. If your doctor has determined your body does not produce enough progesterone on its own, progesterone injection may be prescribed to provide the progesterone you need.

When you do not produce enough progesterone, menstrual irregularities can occur.

Progesterone injection can provide you with the progesterone needed during a normal menstrual cycle.

Possible side effects of progesterone injection

Risks of progesterone injection

Abnormal blood clotting. Blood clots have been reported with the use of estrogens and progestational drugs (alone or in combination). If blood clots do form in your bloodstream, they can cut off the blood supply to vital organs, causing serious problems. These problems may include a stroke (by cutting off blood to part of the brain), a heart attack (by cutting off blood to part of the heart), a pulmonary embolus (by cutting off blood to part of the lungs), or other problems. Any of these conditions may cause death or serious long-term disability. Call your doctor immediately if you suspect you have any of these conditions. He or she may advise you to stop using this drug.

Precautions
Be alert for unusual signs and symptoms. If any of these warning signals (or any other unusual symptoms) happen while you are using progesterone injection, call your doctor immediately:

• Abnormal bleeding from the vagina.

• Pains in the calves or chest, a sudden shortness of breath or coughing blood indicating possible clots in the legs, heart, or lungs.

• Severe headache or vomiting, dizziness, faintness, or changes in vision or speech, weakness or numbness of an arm or leg indicating possible clots in the brain or eye.

• Breast lumps, which could be associated with fibrocystic disorders, fibroadenoma, or breast cancer. (Ask your doctor or healthcare provider to show you how to examine your breasts monthly.)

• Yellowing of the skin and/or white of the eyes indicating possible liver problems.
