The following are some general, educational guidelines for taking Viagra. You can get a professional medical advice from your physician or health care provider.

*

Viagra is taken orally (swallowed by mouth).
*

Don’t take Viagra more than once a day.
*

Don’t take Viagra within 24 hours of taking another ED drug.
*

Don’t take Viagra if you take any other medication that contains nitrates.
*

Take Viagra about 30-60 minutes before sexual activity to allow the medication to take effect. You can stick with what gives you the best results.
*

Swallow the tablet with a glass of water.
*

Having a meal before taking Viagra or not only affects the time the pill takes to start working. Usually taking a high fat meal before taking Viagra would delay the drug’s effects.
*

Don’t take a higher dosage than that specified in your prescription. Usually doctors advice their patients to increase the dosage if the lower ones are not working as effective as they should be.
*

If an erection lasts for more than 4 hours, seek medical help from your doctor or health care provider.
*

Follow your doctor’s directions on your prescription label, as he/she knows more about your specific health condition.
