Cardiovascular side effects have included hypertension, and edema with and without congestive heart failure.
Endocrine side effects have included gynecomastia as a frequent and sometimes persistent side effect. Cautious use is recommended in patients with existing gynecomastia.
During exogenous administration of androgens, endogenous testosterone (the active ingredient contained in Testim) release is inhibited through feedback inhibition of pituitary luteinizing hormone (LH). Large doses of exogenous androgens may suppress spermatogenesis through inhibition of pituitary follicle stimulating hormone (FSH).
Androgens may decrease levels of thyroxin binding globulin resulting in decreased total T4 serum levels and increased resin uptake of T3 and T4. Free thyroid hormone levels remain unchanged and there is no clinical evidence of thyroid dysfunction.
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.
Virilization of children has been reported due to secondary exposure to testosterone. Signs and symptoms have included inappropriate enlargement of the penis or clitoris, premature development of pubic hair, increased erections and libido, aggressive behavior, and advanced bone age. In most cases, these signs and symptoms regressed with removal of the exposure to testosterone. In a few cases, however, enlarged genitalia did not fully return to age-appropriate normal size and bone age remained modestly greater than chronological age.
Renal side effects have included retention of nitrogen, sodium, potassium, chloride, water and phosphorus, and decreased urinary excretion of calcium.
Hepatic side effects have included life-threatening peliosis hepatitis and hepatic abnormalities including hepatic neoplasms and hepatocellular carcinomas following prolonged therapy with high doses of androgen. Tumor regression did not occur in all cases following medication withdrawal.
Cholestatic hepatitis, jaundice, and abnormal liver function tests have occurred during androgen therapy. Drug-induced jaundice is usually reversible following drug discontinuation.
Genitourinary side effects following chronic administration and/or large dosages of testosterone (the active ingredient contained in Testim) have included oligospermia and decreased ejaculatory volume. Elderly male patients have experienced prostatic enlargement resulting in urinary obstruction. Priapism and excessive stimulation has developed. Other urinary side effects have included nocturia, urinary hesitancy, urinary incontinence, urinary retention, urinary urgency, and weak urinary system.
In female patients the use of androgens has resulted in virilization including deepening voice, hirsutism, acne, clitomegaly (not reversible), and menstrual abnormalities. Discontinuation of testosterone at signs of mild virilization may prevent irreversible virilization.
Metabolic side effects have included osteolytic-induced hypercalcemia in immobilized patients or those with metastatic breast disease. Increased cholesterol levels and acute intermittent porphyria have been reported.
Other side effects have included virilization in female patients. Virilization included deepening voice, hirsutism, acne, clitomegaly (not reversible), and menstrual abnormalities.
Female sexual partners of men using topical testosterone (the active ingredient contained in Testim) (residual on skin) have reported virilization.
Dermatologic side effects have included hirsutism, acne, male-patterned baldness and seborrhea. Dermal reactions have been the most commonly reported side effects for transdermal testosterone (the active ingredient contained in Testim) and occur primarily at the site of application. Dermal effects have included 3 types: irritation including mild to moderate erythema (to 6%), induration (3%), itching (12%), and burning (3%); allergic contact dermatitis including pruritus (to 37%), vesicles (6%), and rash (2%); and burn-like blisters (12%).
Discontinuation rates for transdermal testosterone were as follows: due to chronic skin irritation (5%), allergic dermal reactions (4%), and burn-like, usually a single site (0%).
Triamcinolone 1% cream applied sparingly to skin under the reservoir reduced irritation and did not interfere with testosterone absorption. Ointment formulations reduce testosterone absorption.
Gastrointestinal side effects have included nausea and vomiting.
Testosterone is involved in termination of linear bone growth by closure of the epiphyseal growth centers. Appropriate monitoring of bone age is recommended during testosterone (the active ingredient contained in Testim) use in healthy males with delayed puberty.
Musculoskeletal side effects have included myalgia and pain.
Hematologic side effects have included alteration in clotting factors II, V, VII and X and polycythemia due to increased red cell production. Anemia has also been reported.
Hypersensitivity side effects have included rash and anaphylactoid reactions.
Local side effects have included inflammation and pain at injection or dermal application site.
Nervous system side effects have included altered libido (increased/decreased), headache (to 5%), anxiety, depression, generalized paresthesia, or sleep apnea syndrome.
Oncologic side effects have included carcinoma of the prostate, hepatic neoplasms, and hepatocellular carcinomas.
Respiratory side effects have included reports of potentiation of sleep apnea, particularly in obese patients or those with chronic lung disease. There have been rare postmarketing reports of transient reactions involving urge to cough, coughing fits, and respiratory distress immediately after the injection of testosterone (the active ingredient contained in Testim) enanthate, an oil-based depot preparation.
