12 CLINICAL PHARMACOLOGY
Guaifenesin is an expectorant which increases respiratory tract fluid secretions and helps to loosen phlegm and bronchial secretions. By reducing the viscosity of secretions, guaifenesin increases the efficiency of the cough reflex and of ciliary action in removing accumulated secretions from the trachea and bronchi. Guaifenesin is readily absorbed from the gastrointestinal tract and is rapidly metabolized and excreted in the urine. Guaifenesin has a plasma half-life of one hour. The major urinary metabolite is β-(2-methoxyphenoxy) lactic acid.
1 INDICATIONS & USAGE
This product is indicated for the temporary relief of coughs associated with respiratory tract infections and related conditions such as sinusitis, pharyngitis, bronchitis, and asthma, when these conditions are complicated by tenacious mucus and/or mucus plugs and congestion. This product is effective in a productive as well as a non-productive cough which tends to injure the mucus membrane of the air passages.
4 CONTRAINDICATIONS
This product is contraindicated in patients with hypersensitivity to guaifenesin.
WARNINGS
Before prescribing medication to suppress or modify a cough, it is important that the underlying cause of the cough is identified, that modification of the cough does not increase the risk of clinical or physiological complications, and that appropriate therapy for the primary disease is instituted.
PRECAUTIONS
DRUG & OR LABORATORY TEST INTERACTIONS
Guaifenesin may increase renal clearance for urate and thereby lower serum uric acid levels. Guaifenesin may produce an increase in urinary 5-hydroxyindoleacetic acid and may, therefore, interfere with the interpretation of this test for the diagnosis of carcinoid syndrome. It may also falsely elevate the VMA test for catechols. Administration of this drug should be discontinued 48 hours prior to the collection of urine specimens for such tests.
1 CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY
No data are available on the long-term potential for carcinogenesis, mutagenesis, or impairment of fertility in animals or humans.
1 PREGNANCY
Category C: Animal reproduction studies have not been conducted with guaifenesin. It is also not known whether guaifenesin can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Guaifenesin should be given to a pregnant woman only if clearly needed.
3 NURSING MOTHERS
It is not known whether guaifenesin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when guaifenesin is administered to a nursing woman and a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
4 PEDIATRIC USE
Appropriate studies on the relationship of age to the effects of guaifenesin have not been performed in the pediatric population. However, no pediatric-specific problems have been documented to date.
5 GERIATRIC USE
Appropriate studies on the relationship of age to the effects of guaifenesin have not been performed in the geriatric population. However, no geriatric-specific problems have been documented to date.
6 ADVERSE REACTIONS
No serious side effects from guaifenesin have been reported.
10 OVERDOSAGE
Overdosage with guaifenesin is unlikely to produce toxic affects since its toxicity is low. Guaifenesin, when administered by stomach tube to test animals in doses up to 5 gm/kg produced no signs of toxicity. In severe cases of overdosage, treatment should be aimed at reducing further absorption of the drug. Gastric emptying (Syrup of Ipecac) and/or lavage is recommended as soon as possible after ingestion.
2 DOSAGE & ADMINISTRATION
Adults and adolescents over 12: One tablet every 12 hours, not to exceed 2 tablets (2400 mg) in 24 hours. Children 6 - 12: One-half tablet every 12 hours, not to exceed one tablet (1200 mg) in 24 hours. Children 2 - 6: Only as directed by a physician.
