The recommended starting dose of Viagra is 50mg, taken approximately one hour before sexual activity. However, your doctor may prescribe 100mg if 50mg proves insufficient, or reduce it to 25mg if side effects are experienced.
Factors Influencing Dosage
Several factors influence the appropriate Viagra dosage. Your age, overall health, and any other medications you are taking play a significant role. Liver or kidney problems can impact how your body processes the medication, potentially requiring a lower dose. Similarly, certain heart conditions may necessitate careful dose adjustment under medical supervision. Always consult your doctor before adjusting your dosage.
Frequency and Timing
Viagra is typically taken as needed, not more than once per day. Taking it more frequently than prescribed won’t enhance its effects and may increase the risk of side effects. For optimal results, take it about an hour before anticipated sexual activity, allowing sufficient time for it to take effect. The effects usually last for 4-5 hours.
Possible Side Effects
Common side effects include headache, flushing, nasal congestion, and visual disturbances. Less common but more serious side effects, such as prolonged erection (priapism), sudden vision loss, or hearing loss, require immediate medical attention. If you experience any concerning side effects, contact your doctor promptly.
Precautions
Do not take Viagra if you have a history of heart problems, low blood pressure, or certain eye conditions. Also avoid consuming grapefruit or grapefruit juice, as it can interfere with Viagra’s metabolism. Interaction with other medications is possible, so inform your doctor about all medications, including over-the-counter drugs and supplements, you are currently using. Always follow your doctor’s instructions carefully.
