Testosterone Replacement Therapy
AndroGel, an androgen, is indicated for replacement therapy in adult males for conditions associated with a deficiency or absence of endogenous testosterone:
- Primary Hypogonadism (Congenital or Acquired) - testicular failure due to cryptorchidism, bilateral torsion, orchitis, vanishing testis syndrome, orchiectomy, Klinefelter's syndrome, chemotherapy, or toxic damage from alcohol or heavy metals. These men usually have low serum testosterone levels and gonadotropins (FSH, LH) above the normal range.
- Hypogonadotropic Hypogonadism (Congenital or Acquired) - idiopathic gonadotropin or luteinizing hormone-releasing hormone (LHRH) deficiency or pituitary-hypothalamic injury from tumors, trauma, or radiation. These men have low testosterone serum levels but have gonadotropins in the normal or low range.
DOSAGE AND ADMINISTRATION
The recommended starting dose of AndroGel is 5 g once daily (preferably in the morning) to clean, dry, intact skin of the shoulders and upper arms and/or abdomen (area of application should be limited to the area that will be covered by the patient's short sleeve t-shirt). AndroGel must not be applied to the genitals. AndroGel is supplied as either a pump or in individual packets. After applying the gel, the application site should be allowed to dry for a few minutes prior to dressing. Avoid fire, flames or smoking until the gel has dried since alcohol based products, including AndroGel, are flammable. Hands should be washed with soap and water after AndroGel has been applied, [see WARNINGS AND PRECAUTIONS].
Patients should be instructed to prime the pump before using it for the first time by fully depressing the pump mechanism (actuation) 3 times and discard this portion of the product to assure precise dose delivery. After the priming procedure, patients should completely depress the pump one time (actuation) for every 1.25 g (AndroGel Pump) of product required to achieve the daily prescribed dosage. The product may be delivered directly into the palm of the hand and then applied to the desired application sites, either one pump actuation at a time or upon completion of all pump actuations required for the daily dose. Alternatively, the product can be applied directly to the application sites. Application directly to the sites may prevent loss of product that may occur during transfer from the palm of the hand onto the application sites. Table 1 has specific dosing guidelines for adult males when the 75 g AndroGel Pump is used.
Table 1: Specific Dosing Guidelines for Using the Adult Multi-Dose
|Prescribed Daily Dose||Number of Pump Actuations in 75 g Pump|
|5g||4 (once daily)|
|7.5 g||6 (once daily)|
|10 g||8 (once daily)|
The entire contents should be squeezed into the palm of the hand and immediately applied to the application sites. Alternately, patients may squeeze a portion of the gel from the packet into the palm of the hand and apply to application sites. Repeat until entire contents have been applied.
Dose Adjustment and Patient Assessments
- To ensure proper dosing, serum testosterone levels should be measured at intervals and replaced to serum testosterone levels in the normal range. If the serum testosterone concentration is below the normal range, the daily AndroGel dose may be increased from 5 g to 7.5 g and from 7.5 g to 10 g for adult males as instructed by the physician. If the serum testosterone concentration exceeds the normal range, the daily AndroGel dose may be decreased. If the serum testosterone concentration consistently exceeds the normal range at a daily dose of 5 g, AndroGel therapy should be discontinued.
The following is general advice for treating and monitoring adult patients on AndroGel. No specific recommendations can be made.
- Prescribers should be aware that testosterone is contraindicated in men with known or suspected prostate cancer. Therefore, evaluation for prostate cancer prior to initiation of AndroGel therapy is appropriate [see CONTRAINDICATIONS].
- Based on results from controlled studies, serum PSA may rise when taking AndroGel. Therefore, periodic assessment of serum PSA is recommended in patients taking AndroGel [see ADVERSE REACTIONS].
- Based on results from controlled studies, worsening of BPH may occur in patients taking AndroGel [see ADVERSE REACTIONS]. Therefore, periodic assessments for signs and symptoms of BPH are recommended in patients taking AndroGel.
- Hematocrit, serum lipid profile, and liver function test should be monitored in patients taking AndroGel [see WARNINGS AND PRECAUTIONS].
