Take one 100mg tablet of generic Viagra orally, approximately one hour before anticipated sexual activity. Swallow the tablet whole with a glass of water.
Do not take more than one tablet in a 24-hour period. The effects typically last 4-5 hours. Individual responses vary; some men experience effects sooner or for a longer duration.
Factors Influencing Dosage
Your doctor might adjust your dosage based on your individual health and response to treatment. Pre-existing health conditions, such as heart problems or liver disease, can influence the appropriate dose.
Potential Interactions
| Nitrates | Dangerous drop in blood pressure. Avoid concurrent use. |
| Alpha-blockers | Increased risk of low blood pressure. Doctor supervision advised. |
| Certain antifungals | May increase Viagra’s effects. |
Always inform your doctor about all medications you are currently taking, including over-the-counter drugs and herbal supplements, before starting Viagra. This information helps prevent potentially harmful interactions.
Missed Dose
Generic Viagra is taken as needed, not on a regular schedule. Therefore, a missed dose does not require action. Simply take a dose when needed for sexual activity.
