Androgel (Testosterone Transdermal) - Drug Interactions, Contraindications, Overdosage, etc

 
 



DRUG INTERACTIONS

Insulin

Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens. In diabetic patients, the metabolic effects of androgens may decrease blood glucose and, therefore, insulin requirements.

Corticosteroids

The concurrent use of testosterone with ACTH or corticosteroids may result in increased fluid retention and should be monitored cautiously, particularly in patients with cardiac, renal or hepatic disease.

Oral Anticoagulants

Changes in anticoagulant activity may be seen with androgens. More frequent monitoring of INR and prothrombin time are recommended in patients taking anticoagulants, especially at the initiation and termination of androgen therapy.

OVERDOSAGE

There is one report of acute overdosage with use of an approved injectable testosterone product: this subject had serum testosterone levels of up to 11,400 ng/dL with a cerebrovascular accident. Treatment of overdosage would consist of discontinuation of AndroGel together with appropriate symptomatic and supportive care.

CONTRAINDICATIONS

AndroGel should not be used in any of the following patients:

  • Men with carcinoma of the breast or known or suspected carcinoma of the prostate [see Warnings and Precautions Adverse Reactions (6.1), and Nonclinical Toxicology].
  • Women who are or may become pregnant, or who are breastfeeding. AndroGel can cause fetal harm when administered to a pregnant woman. AndroGel may cause serious adverse reactions in nursing infants. Exposure of a female fetus or nursing infant to androgens may result in varying degrees of virilization. Pregnant women or those who may become pregnant need to be aware of the potential for transfer of testosterone from men treated with AndroGel [see Warnings and Precautions and Use in Specific Populations (8.1, 8.3)].
  • Men with known hypersensitivity to any of its ingredients, including alcohol and soy products.

DRUG ABUSE AND DEPENDENCE

Controlled Substance

AndroGel contains testosterone, a Schedule III controlled substance as defined by the Anabolic Steroids Control Act.

Oral ingestion of AndroGel will not result in clinically significant serum testosterone concentrations due to extensive first-pass metabolism.
