For first-time use, the typical starting dose of Viagra (sildenafil) is 50 mg. This dosage is recommended to be taken about 30 minutes to 1 hour before anticipated sexual activity. However, Viagra can be taken anywhere from 30 minutes to 4 hours before sexual activity. The effectiveness and duration can vary among individuals, but it usually lasts for about 4 to 6 hours.
It's essential to follow your healthcare provider's instructions regarding the dosage. They may adjust the dose based on your response to the medication and any side effects you experience. For some men, a lower dose of 25 mg may be effective and can reduce the risk of side effects. For others, if 50 mg does not provide the desired effect, a higher dose of 100 mg may be prescribed.
Do not take more than one dose of Viagra in a 24-hour period. Taking higher doses than recommended or more frequently than advised can increase the risk of side effects and complications, such as low blood pressure, priapism (a prolonged and painful erection), and other adverse effects.
It's crucial to consult with a healthcare provider before starting Viagra to ensure it is safe for you, especially if you have underlying health conditions or are taking other medications that could interact with sildenafil. Your doctor will consider your overall health, medical history, and any potential drug interactions before determining the appropriate starting dose for you.
