Sildenafil Dosage Guide: How Much to Take for Best Results

Standard Dosing Options

For most men, doctors start with a 50 mg tablet taken about an hour before sexual activity. You can take it anywhere from 30 minutes to 4 hours ahead. If 50 mg works well, you can keep using it. If you feel the effect is weak or you notice strong headaches, talk to your doctor about adjusting the dose.

The common next steps are:

25 mg: Good for men over 65, those with liver or kidney issues, or anyone who gets side effects at 50 mg.

100 mg: Reserved for men who didn’t respond to 50 mg and have no health problems that limit a higher dose.

Never take more than one tablet in 24 hours. Taking two doses back‑to‑back can cause a dangerous drop in blood pressure.

Factors That Change the Dose

Several personal factors tell you whether 25 mg, 50 mg, or 100 mg is best:

Age: Older men often start lower because the body processes drugs slower.

Health conditions: Heart disease, severe liver or kidney disease, or low blood pressure usually mean a lower starting dose.

Other meds: Nitrates (often prescribed for chest pain) clash badly with sildenafil. Some antibiotics or antifungals also raise sildenafil levels, so a reduced dose is safer.

Alcohol and food: Heavy drinking or a very fatty meal can slow the drug’s absorption, making the effect feel weaker. Adjust timing rather than dose.

Always tell your doctor about every prescription, over‑the‑counter drug, and supplement you use. A quick chat can prevent a nasty interaction.

When you first try sildenafil, give it a few attempts before deciding it isn’t right. The drug needs a little time to work, and the right dose varies from person to person.

Finally, keep a few safety reminders in mind:

Never mix sildenafil with illegal drugs like poppers.

If you feel a sudden vision change, chest pain, or an erection lasting longer than 4 hours, seek medical help right away.

Store the tablets in a cool, dry place and keep them out of reach of children.

By starting with the recommended dose, watching how your body reacts, and adjusting under a doctor’s guidance, you can enjoy the benefits of sildenafil without unnecessary risks. Got more questions? Ask your pharmacist or doctor – they’re the best source for a dose plan that fits your life.
