How long does Viagra last?

Viagra works by increasing blood flow to the penis, allowing you to achieve and maintain an erection. It takes effect on average around 30 minutes after taking a dose, but can be taken anywhere from 4 hours to 30 minutes before sex. Sildenafil lasts for approximately 4 hours, meaning it will stay active in your body for that period of time.

The first effects of Viagra are usually noticed within 15 minutes after taking the pill, with improved arousal and increased blood flow going into the penis being felt within 30 minutes of dosing with sildenafil citrate tablets or sildenafil citrate capsules (depending on which option you choose). As this continues throughout your period of sexual activity—which may last as long as two hours—you should notice that there is no need for additional lubrication or stimulation because this will also occur naturally through regular breathing patterns during intercourse without being necessary due to any problems associated with erectile dysfunction before taking Viagra.”

Sildenafil is a PDE5 inhibitor, which means it works by increasing blood flow to the penis. The medication can be taken up to 4 hours before sex and without food. It’s important to note that sildenafil has not been proven effective for long-term use or in men who are already taking medications that affect sexual function.

The most common side effects of this drug are headache, facial flushing and indigestion. If these symptoms persist or become bothersome, talk to your doctor.

Viagra works for about 4 hours after you take it. The drug can take up to 30 minutes to begin working, but then it will be working for 4 hours. It’s important that you don’t take your next dose until at least four hours have passed since the last one because this is how long viagra stays in your system and how long it takes for the effects of one dose of viagra (or another brand) to wear off completely.

If you’re taking more than one dose a day, make sure that there’s enough time between doses so that all three aren’t taken at once!

Conclusion

Viagra works for men who want to have sex with their partners, but it can be difficult to tell if you’re experiencing the full effects of this medication. If you notice any symptoms after taking Viagra, or if your erection lasts less than 4 hours, contact your doctor immediately!
