How to take it

Take sildenafil about one hour before you plan to have sex. Beginning in about 30 minutes and for up to 4 hours, sildenafil can help you get an erection when you are sexually excited. If you take sildenafil tablets after a high-fat meal (such as a cheeseburger and french fries), the medicine may take a little longer to start working. Sildenafil Citrate will only help you get an erection when you are sexually excited. You will not get an erection just by taking the pill.

Choosing Strength

The recommend starting dose for sildenafil is one 50mg tablet taken 1 hour before sexual activity. If you achieve the desired effect but are suffering from side effects, try lowering the dose to 25mg. If after trying 50mg tablets four times without the desired effect, and you are not experiencing side effects, increase the dose to 100mg. If after trying 100mg 8 separate times without effect you should cease treatment and consult your doctor. You should not take sildenafil more than once a day as this will have not increase the effectiveness and may increase the likelihood of experiencing side effects.

Side Effects

Like all medicines, sildenafil can cause some side effects. These effects are usually mild to moderate and usually don’t last longer than a few hours. Some of these side effects are more likely to occur with higher doses. The most common side effects of sildenafil are headache, flushing of the face, and upset stomach. Less common side effects that may occur are temporary changes in color vision (such as trouble telling the difference between blue and green objects or having a blue color tinge to them), eyes being more sensitive to light, or blurred vision.
