Delatestryl Dosage

Prior to initiating DELATESTRYL, confirm the diagnosis of hypogonadism by ensuring that serum testosterone concentrations have been measured in the morning in the morning on at least two separate days and that these serum testosterone concentrations are below the normal range.

Dosage and duration of therapy with DELATESTRYL® (Testosterone Enanthate Injection, USP) will depend on age, sex, diagnosis, patient’s response to treatment, and appearance of adverse effects. When properly given, injections of DELATESTRYL are well tolerated. Care should be taken to slowly inject the preparation deeply into the gluteal muscle, being sure to follow the usual precautions for intramuscular administration, such as the avoidance of intravascular injection (see PRECAUTIONS).

In general, total doses above 400 mg per month are not required because of the prolonged action of the preparation. Injections more frequently than every two weeks are rarely indicated. NOTE: Use of a wet needle or wet syringe may cause the solution to become cloudy; however this does not affect the potency of the material. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. DELATESTRYL is a clear, colorless to pale yellow solution.

Male hypogonadism: As replacement therapy, i.e., for eunuchism, the suggested dosage is 50 to 400 mg every 2 to 4 weeks.

In males with delayed puberty: Various dosage regimens have been used; some call for lower dosages initially with gradual increases as puberty progresses, with or without a decrease to maintenance levels. Other regimens call for higher dosage to induce pubertal changes and lower dosage for maintenance after puberty. The chronological and skeletal ages must be taken into consideration, both in determining the initial dose and in adjusting the dose. Dosage is within the range of 50 to 200 mg every 2 to 4 weeks for a limited duration, for example, 4 to 6 months. X-rays should be taken at appropriate intervals to determine the amount of bone maturation and skeletal development (see INDICATIONS AND USAGE, and WARNINGS).

Palliation of inoperable mammary cancer in women: A dosage of 200 to 400 mg every 2 to 4 weeks is recommended. Women with metastatic breast carcinoma must be followed closely because androgen therapy occasionally appears to accelerate the disease.
