Usual Adult Dose for Hypogonadism - Male

10 to 50 mg orally once a day

• Adjust dose based on patient's response and appearance of adverse reactions

Comments:

• Prior to initiating, confirm hypogonadism diagnosis by ensuring serum testosterone concentrations have been measured in the morning on at least 2 separate days and these serum testosterone concentrations are below the normal range.
• Safety and efficacy in men with age-related hypogonadism (also referred to as late-onset hypogonadism) have not been established.

Uses: For replacement therapy in conditions associated with a deficiency or absence of endogenous testosterone such as congenital or acquired primary hypogonadism or congenital or acquired hypogonadotropic hypogonadism.

Usual Adult Dose for Breast Cancer-Palliative

50 to 200 mg orally once a day

Comments:

• Use of androgen therapy in women should be made by an oncologist with expertise in this field; androgen therapy occasionally appears to accelerate disease.
• Some premenopausal women with hormone-responsive therapy have benefited from androgen therapy.

Use: Adjunctive therapy in women with advancing inoperable breast cancer who are 1 to 5 years postmenopausal.

Delayed Puberty:

• Dosing generally starts at the lower end of the dosing range
• Titrate according to patient response and tolerance

Comments:

Uses:

• For replacement therapy in conditions associated with a deficiency or absence of endogenous testosterone such as congenital or acquired primary hypogonadism or congenital or acquired hypogonadotropic hypogonadism.
