How to use Sildenafil

What to expect with Sildenafil

Possible side effects of Sildenafil:

• An allergic reaction, the symptoms of which include sudden wheezing, difficulty breathing, dizziness, swelling of the eyelids, face, lips or throat;
• Chest pain, which is uncommon, but if it occurs during or after sex, you should get into a comfortable sitting position, breath deeply and try to relax. Do not take nitrates to treat your chest pain.
• A sudden decrease in vision or a sudden loss of vision.
• Ringing in your ears, dizziness, a severe skin rash, seizures or an erection that lasts longer than four hours.

Your 6 month check up

It is important for you to have a check up with your GP within 6 months of using Sildenafil, even if you feel healthy and well. This is because erectile dysfunction could be an early warning sign of other underlying health issues, such as heart and blood pressure problems, diabetes, high blood pressure or high cholesterol.
