What is Sildenafil Pfizer used for?

Sildenafil Pfizer is used to treat adult men suffering from erectile dysfunction (ED), also known as impotence. ED means an inability to get or maintain a good enough erection to achieve satisfactory intercourse.

How to use Sildenafil Pfizer?

Sildenafil Pfizer can be taken with or without food and should be taken about one hour before sexual activity. The tablet should be swallowed whole with a glass of water. Sildenafil Pfizer only produces an erection when you are sexually aroused. It normally takes about 30 to 60 minutes to take effect (or longer if you have had a rich meal), although this may vary depending on the person. If Sildenafil Pfizer does not produce an erection, or if you lose your erection prematurely, consult your doctor.

Dosage

The recommended starting dose for Sildenafil Pfizer is 50 mg. This medicine can cause you to experience more side effects or make side effects worse. Doses above 100 mg do not increase its effectiveness. Always follow your doctor’s instructions about how to take Sildenafil Pfizer. When in doubt, consult your doctor or pharmacist.

Side effects

As with all medicines, Sildenafil Pfizer may cause side effects, although of course not everybody will suffer from them. The side effects that have been reported are almost always mild to moderate and short-lived, with the most common being: facial flushing, digestive problems, visual disturbances (e.g. changes in colour vision, sensitivity to light, blurred vision), nasal congestion and dizziness.

When not to use Sildenafil Pfizer

Sildenafil Pfizer should not be used if you are allergic to any of the ingredients in this medicine (see the package leaflet for ingredients). You should also not use it if you are taking any form of nitrate medication, as this can result in dangerously low blood pressure. Nitrates are commonly used for angina pectoris (chest pain). Be sure to inform your doctor of all medicines that you are currently taking. If you are using products that release nitrogen monoxide, such as amyl nitrite (‘poppers’), this can also result in dangerously low blood pressure.

Driving ability / alcohol

Drinking alcohol can temporarily impair your ability to get an erection. To gain maximum effect from Sildenafil Pfizer, we advise you to limit your alcohol consumption before sex.

This medicine may cause dizziness and temporary visual disturbances. You should make sure you are aware of your reactions to this medicine before driving or operating machinery.
