Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Methyldopa is a centrally acting alpha-2 adrenergic agonist. Its active metabolite, alpha-methylnorepinephrine, stimulates presynaptic alpha-2 receptors in the central nervous system, reducing sympathetic outflow from the brainstem and decreasing peripheral vascular resistance, leading to lowered blood pressure.
Fingolimod is a sphingosine 1-phosphate receptor modulator that sequesters lymphocytes in lymph nodes, reducing central nervous system immune cell infiltration.

250 mg orally twice daily, increased as needed every 2-3 days; usual maintenance 500 mg to 2 g/day in 2-4 divided doses; maximum 3 g/day.
Adults: 1 tablet (methyltestosterone 2.5 mg, ethinyl estradiol 0.025 mg) orally once daily, with food.
1.5–2 hours (terminal elimination half-life); clinical context: Renal impairment prolongs half-life (up to 4–6 hours in severe impairment), necessitating dose adjustment.
2.5-3.5 hours (terminal half-life); oral administration may require multiple daily doses for stable levels.
Primarily hepatic metabolism via conjugation and O-methylation; also undergoes decarboxylation and deamination. Active metabolites include alpha-methyldopamine and alpha-methylnorepinephrine.
Metabolized primarily by CYP4F2, with minor contributions from CYP2D6, CYP2E1, CYP3A4, and CYP1A2. Undergoes biotransformation to an inactive metabolite.
Renal: ~70% as unchanged drug and metabolites (sulfate conjugate, O-methylated derivatives); fecal/biliary: ~20%; <5% removed by hemodialysis.

Oral: 3-6% (extensive first-pass metabolism); IM: 100%.
GFR >50 m L/min: no adjustment; GFR 10-50 m L/min: interval every 12-24 hours; GFR <10 m L/min: interval every 24-48 hours or 250 mg every 36-48 hours.
GFR 10-50 m L/min: reduce dose by 50%. GFR <10 m L/min: avoid use.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: avoid use or reduce dose by 75%.
Child-Pugh A: reduce dose by 50%. Child-Pugh B: avoid use. Child-Pugh C: contraindicated.
10 mg/kg/day orally in 2-4 divided doses, increased gradually; maximum 65 mg/kg/day or 3 g/day.
Not recommended for use in children due to risk of premature epiphyseal closure and virilization.
Initial dose 250 mg once or twice daily; increase slowly; monitor for hypotension, sedation, and bradycardia; avoid in patients with pre-existing bradycardia or heart block.
Use with caution; consider lower starting dose due to increased risk of fluid retention, hypertension, and prostatic hypertrophy in males.
None
Risk of bradyarrhythmia and atrioventricular block, requiring first-dose monitoring for 6 hours. Fatal infections, including opportunistic infections, have occurred. Macular edema has been reported.
Hepatic toxicity (fatal hepatic necrosis reported); hemolytic anemia (positive Coombs test common, may indicate hemolysis); sedation/drowsiness (impair mental alertness); orthostatic hypotension; caution in renal impairment (dose adjustment required); may cause positive direct Coombs test, which interferes with crossmatching; possible rebound hypertension upon abrupt discontinuation.
May cause bradycardia and AV block; monitor heart rate after first dose. Increased risk of infections, including herpes viruses and cryptococcal meningitis. Macular edema, especially in patients with diabetes or uveitis. Posterior reversible encephalopathy syndrome (PRES). Respiratory effects, including decreased FEV1 and DLCO. Hepatic injury; monitor liver enzymes.
Active hepatic disease (acute hepatitis, cirrhosis); prior methyldopa-induced hepatic dysfunction; concurrent MAO inhibitor therapy; hypersensitivity to methyldopa; pheochromocytoma.
Recent myocardial infarction, unstable angina, stroke, transient ischemic attack, decompensated heart failure, history of Mobitz type II 2nd or 3rd degree AV block, sick sinus syndrome unless pacemaker is present, or severe untreated sleep apnea.
Avoid excessive sodium intake, as it can counteract the antihypertensive effect. No specific food interactions reported, but alcohol may potentiate hypotension and sedation. Iron supplements may reduce absorption of methyldopa; separate administration by at least 2 hours.
No significant food interactions reported. Avoid excessive alcohol consumption due to hepatotoxic effects.
First trimester: No increased risk of major congenital malformations reported in human studies based on limited data. Second and third trimesters: No known teratogenicity; use for management of chronic hypertension in pregnancy is common, but consider potential for reduced placental perfusion if maternal blood pressure is excessively lowered.
ANDROID-F contains methyltestosterone, a synthetic androgen. Androgens are teratogenic in humans. In first trimester: masculinization of female fetus, including clitoromegaly, labial fusion, and urogenital sinus abnormalities. Second and third trimesters: continued virilization of female fetus; no increased risk of malformations in male fetuses. Contraindicated in pregnancy.
Methyldopa is excreted into breast milk in small amounts (M/P ratio approximately 0.2-0.5). At typical maternal doses, infant exposure is likely subtherapeutic and considered compatible with breastfeeding. Monitor infant for potential hypotension or sedation.
Methyltestosterone is excreted in breast milk. No specific M/P ratio available. May cause virilization in female infants and precocious development in male infants. Breastfeeding is contraindicated during therapy.
Pregnancy may increase volume of distribution and renal clearance, potentially reducing methyldopa plasma concentrations. Dose adjustments may be necessary to maintain blood pressure control; monitor and titrate based on maternal blood pressure response. Typical starting dose: 250 mg orally twice daily; maximum up to 3 g/day in divided doses, but lower doses are often effective.
ANDROID-F is contraindicated in pregnancy; no dosing recommendations for use in pregnancy. No established dose adjustments exist as the drug should not be administered.
ALDOMET (methyldopa) is a centrally acting alpha-2 agonist used primarily for hypertension in pregnancy. Monitor for positive direct Coombs test, which can occur in up to 20% of patients on long-term therapy; this may interfere with cross-matching but rarely causes hemolysis. Hepatic adverse effects, including increased liver enzymes and rarely hepatitis, require monitoring. Sedation and dizziness are common initially; titrate dose slowly. Methyldopa may cause orthostatic hypotension; advise patients to rise slowly. A paradoxical pressor response may occur if given with MAO inhibitors.
Android-F is a brand of methyltestosterone, an androgen used primarily for male hypogonadism. Monitor liver function due to potential hepatotoxicity. Avoid in males with breast or prostate cancer. Use with caution in older patients due to increased risk of prostatic hypertrophy. May suppress clotting factors II, V, VII, and X.
