Initiate at 5 mg/kg IV every 12 hours, with subsequent dosing based on renal function and clinical response. Monitor for neurotoxicity and nephrotoxicity.
Start at low end of dosing range (e.g., testosterone cypionate 50 mg intramuscularly every 4 weeks or gel 25 mg daily) due to potential increased sensitivity and risk of prostatic hypertrophy or cardiovascular events. Monitor serum testosterone, hematocrit, and prostate-specific antigen (PSA).

None
Hypersensitivity reactions including anaphylaxis,Hepatotoxicity,Bone marrow suppression (leukopenia, thrombocytopenia),Potential for drug interactions with agents metabolized by CYP450 isoenzymes
Risk of hepatotoxicity; use with caution in patients with liver disease. Monitor liver function, lipid profile, and prostate-specific antigen (PSA). May cause fluid retention, gynecomastia, priapism, and sleep apnea. Not for use in women who are pregnant or breastfeeding. May accelerate growth of prostate cancer and benign prostatic hyperplasia. Androgenic effects may cause virilization in women.
Hypersensitivity to novobiocin or any component,Severe hepatic impairment,Breastfeeding (due to potential for kernicterus in neonates)
Men with carcinoma of the prostate or breast; history of hypersensitivity to testosterone or any component; women who are pregnant or may become pregnant (risk of fetal harm); patients with severe hepatic or cardiac disease.
Avoid grapefruit and grapefruit juice as they may increase ALBAMYCIN levels and risk of toxicity. No other significant food interactions known.
No known food interactions. However, methyltestosterone can increase appetite and cause weight gain; a balanced diet is recommended.
Albamycin is teratogenic in animal studies; human data limited. Risk group: D. First trimester: Associated with teratogenic effects (e.g., cardiac defects) in animals; avoid unless life-threatening. Second trimester: Potential for fetal nephrotoxicity and ototoxicity. Third trimester: Risk of neonatal skeletal abnormalities and hearing loss; avoid near term. Fetal risk outweighs potential benefit.
Android 10 is a combination of methyltestosterone and ethinyl estradiol. Methyltestosterone is an androgen; exposure during pregnancy, particularly during the first trimester, can cause virilization of the female fetus. Ethinyl estradiol is contraindicated in pregnancy due to risk of fetal harm. Use is contraindicated in all trimesters.
Excreted in human milk; M/P ratio not reported. Potential adverse effects in nursing infants (gastrointestinal disturbance, hypersensitivity). Use with caution; consider alternative therapy. American Academy of Pediatrics suggests use with caution.
Methyltestosterone and ethinyl estradiol are excreted in breast milk. Methyltestosterone may cause virilization in female infants. Ethinyl estradiol may reduce milk production and quality. M/P ratio not available. Breastfeeding is contraindicated.
Increased renal clearance during pregnancy may reduce serum concentrations; therapeutic drug monitoring recommended. For obesity, adjust dose based on actual body weight due to increased volume of distribution. Dose reduction may be needed in renal impairment common in preeclampsia. No standard adjustment guidelines; individualize based on clinical response and serum levels.
Contraindicated in pregnancy; no dosing adjustments apply. If inadvertent use occurs, discontinue immediately.
ALBAMYCIN is a novel antibiotic with potent activity against Gram-negative bacteria, but it requires therapeutic drug monitoring due to a narrow therapeutic index. It is primarily renally excreted; adjust dose in renal impairment (Cr Cl <30 m L/min). Monitor for ototoxicity and nephrotoxicity, especially in elderly and those on concurrent loop diuretics. Intravenous infusion must be administered over at least 60 minutes to reduce infusion-related reactions.
Android 10 is a brand name for methyltestosterone, an androgen and anabolic steroid. Use is restricted to replacement therapy in males with hypogonadism or delayed puberty due to androgen deficiency. Monitor liver function due to risk of peliosis hepatis and hepatocellular carcinoma. Contraindicated in males with breast or prostate cancer. Can cause erythrocytosis; monitor hematocrit. Discontinue if signs of virilization in women or priapism in men. Use caution in elderly due to increased risk of prostatic hypertrophy.
