Puregrey (Sildenafil) 100 mg Tablets – Uses and Side Effects

What it is

Sildenafil is a PDE5 inhibitor, a class of medicines that help increase blood flow to the penis. Puregrey is a brand containing sildenafil as the active ingredient, available in 100 mg tablet strength.

What it's used for

Puregrey (sildenafil) is indicated for the treatment of erectile dysfunction (ED) in men. It helps achieve and maintain an erection only when sexually stimulated.

How it's taken

Typically, sildenafil tablets are taken as needed about 1 hour before sexual activity. The recommended starting dose is often 50 mg, but Puregrey is a 100 mg tablet, which is the maximum single dose. It may be taken 30 minutes to 4 hours before sexual activity. Do not take more than one tablet per day. Always follow your doctor’s instructions and consult a pharmacist if unsure.

Common side effects

Common side effects may include headache, flushing, indigestion, and nasal congestion. Serious side effects include prolonged erection lasting more than 4 hours (priapism), sudden vision loss, hearing loss, and low blood pressure when used with nitrates. Seek emergency care if any of these occur.

Important cautions

Do not use Puregrey if you are taking nitrates (e.g., medicines for chest pain) or riociguat, as it can cause a dangerous drop in blood pressure. Avoid sexual activity if your heart condition makes it risky. Use caution if you have a history of priapism. Stop the medicine and see a doctor if you experience sudden vision or hearing loss.
