Most men find that they tolerate sildenafil well, but as all medicines, sildenafil may cause side effects. 

Common side effects of sildenafil include feeling dizzy or light-headed. These side effects can be made worse if you drink alcohol or take other certain medicines at the same time as the drug. Hot weather, taking exercise, or having a high temperature (fever) may also exacerbate these side effects while taking sildenafil.

If you do experience these side effects, you must let your doctor know and stop taking the medication. It is advisable not to drive or undertake potentially dangerous tasks such as operating heavy machinery.

Sildenafil can rarely cause severe side effects which include allergic reactions, vision disturbances and hearing problems.
