As a doctor with years treating men's health issues, I often prescribe 20mg sildenafil for specific needs. This PDE5 inhibitor relaxes blood vessels. It boosts blood flow where needed.

Sildenafil, the active ingredient in Viagra and generics, targets erectile dysfunction at higher doses. At 20mg, patients use it for pulmonary hypertension. It eases pressure in lung arteries.

Take it orally as tablets. Effects start in 30-60 minutes for ED use. For lung conditions, it works around the clock with regular dosing.

Men report firmer erections with sexual stimulation. It does not create desire. Blood rushes in, sustaining response up to four hours.

In pulmonary arterial hypertension, 20mg three times daily improves exercise capacity. Patients walk farther without shortness of breath. I see real gains in quality of life.

Revatio contains sildenafil citrate at 20mg. Generic versions match exactly. Both deliver identical results safely.

Off label, some use it for altitude issues or Raynaud's. Stick to proven uses. Consult me for your case.

Strengths available

Sildenafil comes in 20mg, 25mg, 50mg, and 100mg tablets. 20mg suits pulmonary hypertension best. Doctors start ED patients at 50mg usually.

Viagra offers 25mg to 100mg. Generics mirror these strengths. 20mg pills split easily if needed.

For kids with PAH, doses adjust by weight. Adults take 20mg thrice daily. Swallow whole with water.

Online pharmacies stock all strengths. 20mg packs save money long term. Bulk buys drop per pill cost.

Revatio 20mg tablets cost less generically now. Pick based on your prescription. I recommend generics for value.

Dosage Guide

• PAH adults: 20mg three times daily.
• ED occasional: 20mg as needed, max once daily.
• Adjust for age or liver issues.
• Take 1 hour before activity for best effect.

Directions for use

Swallow 20mg sildenafil whole. Use water, not grapefruit juice. Empty stomach speeds absorption for ED.

Timing matters. For sex, take 30 minutes to 4 hours prior. Sexual arousal activates it fully.

PAH patients space doses 4-6 hours apart. Never exceed three 20mg daily. Consistency builds steady levels.

With food, delay possible. High fat meals slow onset by an hour. Plan.

If liquid form, use syringe for accuracy. Pharmacists compound it. Shake well before measuring.

Missed PAH dose? Take soon unless near next. Skip double dosing. Set reminders for routine.

Store at room temp. Keep from moisture. Shelf life exceeds two years usually.

Quick Tips

• Avoid alcohol excess; it dulls effects.
• Stay hydrated for best results.
• Track response in journal.

Overdose brings headaches or dizziness. Call doctor if concerned. Most handle 20mg fine.

Common and rare side effects

Headaches top the list at 20mg. Flushing warms face and neck. These fade quickly.

Indigestion or stuffy nose occurs often. Vision tints blue rarely. All pass within hours.

Back pain or muscle aches hit some. Nasal congestion clears with saline. Stay upright post dose.

Rarely, prolonged erection lasts over 4 hours. Seek ER fast; priapism damages tissue. Hearing dips seldom.

Serious risks include heart attack or vision loss. Those with heart disease watch closely. Stop if chest pain strikes.

Blue vision from PDE6 effect in eyes. Temporary and mild usually. Report persistence.

Side Effects Table

Most tolerate well. Start low if new. I monitor first users closely.

Contraindications

Skip sildenafil with nitrates like nitroglycerin. Blood pressure crashes dangerously. Chest pain meds spell trouble.

Riociguat users avoid it too. Hypersensitivity means no go. Allergy history flags risk.

Recent heart attack or stroke bars use. Unstable angina patients wait. Sexual activity itself strains.

Protease inhibitors for HIV multiply levels. Limit to 25mg every 48 hours. Eryromycin slows clearance.

Alpha blockers drop pressure if timed wrong. Space 4 hours apart. I adjust for combo therapy.

Low blood pressure baseline contraindicates. Eye conditions like retinitis pigmentosa caution. Discuss history fully.

Drug Interactions List

• Nitrates: Absolute no.
• Riociguat: Forbidden.
• Protease inhibitors: Dose halve.
• Alpha blockers: Time separate.
• Fungus meds: Monitor levels.
