Maximum power sildenafil citrate tablets?

Do you mean sildenafil for erectile dysfunction (Viagra) or for pulmonary arterial hypertension (Revatio)? The “maximum strength” depends on the use.

- Erectile dysfunction (Viagra)
- Available tablet strengths: 25 mg, 50 mg, 100 mg
- Maximum recommended single dose: 100 mg
- Do not take more than one tablet in 24 hours
- Typical guidance: start at 50 mg (adjust up to 100 mg or down to 25 mg based on effectiveness and tolerability)
- Take about 30–60 minutes before activity; high-fat meals can slow onset
- Don’t use with nitrates or certain heart medications; talk to your doctor about interactions

- Pulmonary arterial hypertension (Revatio)
- Available tablet strengths: 20 mg, 40 mg, 80 mg
- Taken three times daily
- Maximum per-dose: 80 mg (total daily up to 240 mg)
- Dosing is titrated based on tolerance and response

If you can tell me which indication you’re asking about (and your location, since formulations can vary), I can tailor the details and safety notes. If you’re considering changing your dose, please consult a healthcare professional first.
