Penegra 100 mg contains sildenafil citrate and is used to treat erectile dysfunction (ED). After taking Penegra 100 mg, it's generally recommended to wait for a certain period before engaging in sexual activity. Here are some guidelines:

Onset of Action: Penegra 100mg typically starts working within 30 to 60 minutes after ingestion. During this time, sildenafil citrate is absorbed into the bloodstream and begins to exert its effects.

Peak Effectiveness: The peak effectiveness of Penegra 100 mg usually occurs about 1 to 2 hours after taking the medication. This is when sildenafil citrate reaches its maximum concentration in the bloodstream, leading to optimal vasodilation in the penile tissues and improved blood flow to the penis.

Duration of Action: The effects of Penegra 100 mg can last for up to 4 to 6 hours after ingestion. During this time, the medication can help facilitate erections when sexual stimulation occurs.

Based on these factors, it's generally advisable to wait for at least 1 to 2 hours after taking Penegra 100 mg before engaging in sexual activity. This allows sufficient time for the medication to reach peak effectiveness and for you to experience its full benefits.

It's important to note that individual responses to Penegra 100 mg can vary, so the timing may differ from person to person. Additionally, always follow your healthcare provider's instructions and dosage recommendations when using Penegra 100 mg or any medication for erectile dysfunction. If you have any questions or concerns about resuming sexual activity after taking Penegra 100 mg, it's best to consult with your doctor or healthcare provider for personalized advice.
