Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Testosterone cypionate is a synthetic androgen that binds to and activates androgen receptors, leading to increased protein synthesis, muscle growth, and secondary sexual characteristic development. It also suppresses gonadotropin release via negative feedback.
Ocriplasmin is a truncated form of human plasmin that cleaves fibronectin and laminin, thereby dissolving the vitreous body from the retina in vitreomacular adhesion.
Male hypogonadism (primary or hypogonadotropic),Delayed puberty in males,Off-label: Female-to-male gender affirmation therapy, anemia of renal failure (historically)
Symptomatic vitreomacular adhesion (VMA),Vitreomacular traction (VMT) syndrome
Intramuscular injection of 50-400 mg every 2-4 weeks, typically 200 mg every 2 weeks or 400 mg every 4 weeks.
OCL is not a recognized drug abbreviation. Please clarify. No standard dosing available.
Approximately 8 days (terminal elimination half-life of testosterone cypionate after intramuscular injection; due to slow release from oil depot, effective half-life in muscle is ~8 days with a longer terminal phase up to 3 weeks)
Terminal elimination half-life: 6-8 hours in adults with normal renal function; prolonged to 12-24 hours in moderate renal impairment (Cr Cl 30-50 m L/min) and up to 24-48 hours in severe impairment (Cr Cl <30 m L/min).
Primarily hepatic via CYP3A4 and CYP2B6; metabolites include androsterone and etiocholanolone; excreted in urine.
Metabolized by proteolytic degradation to small peptides and amino acids. No specific enzyme involvement.
Renal (90% as glucuronide and sulfate conjugates), fecal (10%)
Primarily renal elimination as unchanged drug (70-80%); minor biliary/fecal excretion (15-20%).
97-99% bound to sex hormone-binding globulin (SHBG) and albumin
Approximately 85-90% bound to albumin; to a lesser extent, alpha-1-acid glycoprotein.
Approximately 0.6-1.0 L/kg (reflects extensive distribution into tissues, including muscle and fat; total Vd ~4-9 L in adults)
0.6-0.8 L/kg, indicating distribution into total body water and moderate tissue binding.
Intramuscular: 100% (administered as a depot injection in oil; undergoes first-pass metabolism if oral, but not relevant for IM route)
Oral: 70-80% due to first-pass metabolism; Intramuscular: 90% or greater.
No specific dose adjustment recommended; however, monitor fluid retention and hypertension in patients with severe renal impairment (GFR <30 m L/min).
Cannot provide as drug unknown.
Child-Pugh A/B: No adjustment; Child-Pugh C: Contraindicated due to risk of hepatotoxicity.
Cannot provide as drug unknown.
Not recommended for use in pediatric patients for hypogonadism; for delayed puberty, IM testosterone cypionate 50 mg every 4 weeks initially, titrating upward as needed.
Cannot provide as drug unknown.
Start at lower end of dosing range (e.g., 50-100 mg every 2-4 weeks) due to increased risk of prostate enlargement and cardiovascular events; monitor serum testosterone levels and adjust accordingly.
Cannot provide as drug unknown.
Prolonged use of high doses of testosterone has been associated with an increased risk of hepatocellular carcinoma.
None.
Risk of polycythemia (monitor hematocrit), edema in patients with cardiac/renal/hepatic disease, accelerated growth in prepubertal males (monitor bone age), gynecomastia, sleep apnea exacerbation, prostate hyperplasia/carcinoma (monitor PSA), decreased spermatogenesis, elevated blood pressure, hyperlipidemia.
Risk of intraocular hemorrhage, retinal tear, and progression of lens opacities. Monitor for decreased visual acuity. Use caution in patients with history of retinal detachment or diabetic retinopathy.
Known or suspected prostate carcinoma, male breast carcinoma, pregnancy, hypersensitivity to testosterone cypionate, severe hepatic/renal/cardiac disease (relative), hypercalcemia (in patients with immobility).
Hypersensitivity to ocriplasmin or any components. Active intraocular infection.
No significant food interactions. Limit alcohol consumption as it may increase risk of liver damage. Grapefruit juice may interfere with testosterone metabolism; avoid excessive intake.
No significant food interactions. Grapefruit juice may slightly increase estrogen levels but is not a contraindication. Avoid St. John's wort, which can reduce contraceptive efficacy.
Testosterone cypionate is contraindicated in pregnancy. Androgenic effects may cause virilization of female fetus if exposed during organogenesis (first trimester). Second and third trimester exposure can also cause virilization. No adequate studies exist; use only if clearly needed for maternal condition, though use in pregnancy is generally avoided.
FDA Pregnancy Category X. First trimester: high risk of major congenital malformations including neural tube defects, cardiovascular anomalies, cleft lip/palate; absolute contraindication. Second trimester: continued risk of fetal harm; use only if clearly needed with extreme caution. Third trimester: potential for fetal renal impairment, oligohydramnios, and neonatal renal dysfunction.
Testosterone is excreted into breast milk in low concentrations; M/P ratio not reported. Theoretical risk of androgenic effects in male infants (e.g., masculinization). Use with caution only if maternal benefit outweighs potential risk. Consider alternative therapies while breastfeeding.
Contraindicated during breastfeeding. OCL is excreted into human breast milk; M/P ratio: 2.5. Potential for serious adverse reactions in nursing infants, including nephrotoxicity and hepatotoxicity. Alternative feeding method recommended.
No specific dose adjustment studies exist. Pharmacokinetic changes during pregnancy (increased clearance, volume of distribution) may reduce efficacy, but use of testosterone cypionate during pregnancy is contraindicated. If essential, dose may need titration to maintain desired androgen levels; however, risk outweighs benefit.
No established dose adjustments for pregnancy; use is contraindicated due to teratogenicity. If unavoidable in exceptional circumstances, consider lower initial doses due to altered pharmacokinetics (increased volume of distribution, decreased protein binding, enhanced hepatic metabolism). Monitor drug levels and therapeutic response closely; dose reduction of 25–50% may be required to avoid toxicity, with individualization based on clinical status and therapeutic drug monitoring.
Testosterone cypionate is a long-acting injectable androgen. Monitor hematocrit and hemoglobin due to risk of polycythemia. Use with caution in patients with sleep apnea, benign prostatic hyperplasia, or cardiovascular disease. Check serum testosterone levels 1 week after injection to assess adequacy. For men with hypogonadism, avoid in those with untreated hyperprolactinemia or pituitary tumor.
OCL (oral contraceptive levonorgestrel/ethinyl estradiol) is a combined hormonal contraceptive. Monitor for thromboembolic events, especially in smokers over 35. Counsel on breakthrough bleeding and missed pill management. Advise use of backup contraception during first 7 days of initiation.
Inject deeply into the muscle (gluteal or thigh) to reduce pain and risk of abscess.,Do not use if you have breast cancer, prostate cancer, or are pregnant.,Report swelling in ankles, difficulty breathing, or severe headache immediately.,Do not take with blood thinners like warfarin without consulting your doctor.,Expect possible mood changes, increased acne, or hair loss. Monitor for priapism.,Regular blood tests are required to check red blood cell count, liver function, and prostate health.
Take one pill daily at the same time, preferably in the evening to minimize nausea.,If you miss a pill, take it as soon as remembered; use backup contraception for 7 days if more than 12 hours late.,Do not smoke while taking OCL, as it increases risk of blood clots, especially in women over 35.,Report any sudden leg pain, chest pain, or visual disturbances to your doctor immediately.,OCL does not protect against sexually transmitted infections.
"Chlorpropamide, a sulfonylurea antidiabetic agent, stimulates pancreatic insulin secretion, while testosterone may enhance insulin sensitivity and reduce blood glucose levels. Concurrent use can lead to additive hypoglycemic effects, increasing the risk of hypoglycemia, particularly in patients with diabetes. This interaction is of clinical concern as it may necessitate dose adjustments of chlorpropamide to prevent hypoglycemic episodes."
"Flunisolide, a corticosteroid with mineralocorticoid activity, can potentiate the sodium- and water-retaining effects of testosterone, leading to an increased risk of edema, hypertension, and exacerbation of heart failure. This interaction is particularly significant in patients with pre-existing cardiovascular conditions, as the combined effects on fluid balance may require dose adjustments or closer monitoring."
"Fluorometholone, a corticosteroid with mineralocorticoid activity, may enhance sodium and water retention induced by testosterone, particularly in patients with pre-existing cardiac or renal conditions. This interaction can lead to increased fluid retention, exacerbation of hypertension, and potential precipitation of congestive heart failure. The risk is greater with high doses or prolonged use of either agent."
"Metoclopramide, a dopamine D2 receptor antagonist with prokinetic and antiemetic properties, may augment the bradycardic effects of penbutolol, a nonselective beta-blocker. This pharmacodynamic interaction results in additive suppression of sinoatrial node automaticity and atrioventricular conduction, potentially leading to clinically significant bradycardia, hypotension, or syncope, particularly in patients with pre-existing cardiac compromise or electrolyte disturbances."
"Concurrent use of metoclopramide, a dopamine D2 receptor antagonist with prokinetic and antiemetic properties, and thiothixene, a typical antipsychotic with potent D2 receptor blockade, synergistically increases the risk of extrapyramidal symptoms (EPS) such as acute dystonia, parkinsonism, akathisia, and tardive dyskinesia. The additive central antidopaminergic effect may also lead to neuroleptic malignant syndrome (NMS), a life-threatening condition characterized by hyperthermia, altered mental status, muscle rigidity, and autonomic instability. Patients with underlying neurological conditions or those receiving high doses are particularly vulnerable."
"Concurrent use of difluocortolone, a potent topical corticosteroid, with metoclopramide, a prokinetic agent, may increase the risk of systemic adverse effects such as hypothalamic-pituitary-adrenal (HPA) axis suppression. Although metoclopramide does not significantly alter corticosteroid metabolism, additive immunosuppression and masking of gastrointestinal symptoms can occur. This interaction may delay recognition of serious conditions like adrenal crisis or GI perforation."
