Overview

Revatio 20mg Tablet contains Sildenafil 20mg (as sildenafil citrate) and is available as a tablet. It is classified as a prescription medicine and may only be obtained with a valid prescription from a registered medical practitioner.

Only product, safety and handling information is published here. Anything beyond that is explained to you directly by your doctor or pharmacist as part of your consultation.

DoctorOnCall is a licensed online pharmacy. Orders for Revatio 20mg Tablet are processed only after a doctor has assessed your suitability and issued a prescription, and every order is checked by a registered pharmacist before it is sent out.

Directions for Use

Take Revatio 20mg Tablet three times a day at evenly spaced intervals, with or without food, to maintain a steady level of medicine in your body. Swallow the tablet whole with water, and try to take each dose at the same three times every day rather than only when needed.

Dosage

The usual dose of Revatio 20mg Tablet for PAH is 20mg taken three times daily, roughly 4-6 hours apart, which is a different regimen from the on-demand dosing used for erectile dysfunction. Your doctor will confirm the correct dose and schedule for your condition and monitor your response over time.

Storage Instructions

Store below 30°C in a dry place, away from direct sunlight and out of reach of children.

Side Effects

  • Headache
  • Flushing (warmth or redness of the face)
  • Dizziness
  • Upset stomach or indigestion
  • Nasal congestion
  • Vision changes (blurred vision or sensitivity to light)
  • Back pain or muscle aches
  • Nausea

Contraindications

  • Known hypersensitivity to sildenafil or any ingredient in this product
  • Concomitant use with any form of nitrate medicine (e.g. glyceryl trinitrate) due to the risk of severe, life-threatening low blood pressure
  • Concomitant use with riociguat, a soluble guanylate cyclase stimulator also used for pulmonary hypertension
  • Severe liver impairment or recent stroke/heart attack, unless specifically assessed by your doctor

Drug / Food Interactions

  • Nitrates and riociguat must never be combined with sildenafil due to dangerous blood pressure drops
  • Alpha-blockers (e.g. for prostate enlargement) may increase the risk of low blood pressure when combined
  • Strong CYP3A4 inhibitors (e.g. ritonavir, ketoconazole, itraconazole) can raise sildenafil blood levels significantly
  • Grapefruit juice may increase sildenafil levels and should be used cautiously

Quick Tips

  • Take all three daily doses at evenly spaced times, not just when symptoms are noticed
  • Never take this medicine together with nitrate medicines or riociguat
  • Attend follow-up appointments to track your exercise capacity and PAH progression
  • Report any sudden change in vision or hearing to your doctor immediately
  • Do not adjust your dose or stop treatment without your doctor’s advice
