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.
