Viagra Online Generic

Instructions

Viagra is usually taken about 1 hour before sexual activity; however, it may be taken anywhere from 4 hours to a half hour before sexual activity. Talk with your doctor about the best way to take Viagra.

Viagra can help you have an erection when sexual stimulation occurs. An erection will not occur just by taking a pill.

Do not take more than the recommended dose or take it more often than once daily, or as directed by your doctor.

If you miss a dose of Viagra and you still intend to engage in sexual activity, take it as soon as you remember. Continue to take it as directed by your doctor.

Dosage

For most patients, the recommended dose is 50 mg taken, as needed, approximately 1 hour before sexual activity. However, Viagra may be taken anywhere from 4 hours to 0.5 hour before sexual activity. Based on effectiveness and toleration, the dose may be increased to a maximum recommended dose of 100 mg or decreased to 25 mg. The maximum recommended dosing frequency is once per day.

Ask your health care provider any questions you may have about how to use Viagra.
