Sildenafil Citrate

Address erectile dysfunction with generic Viagra at up to 95% less than the branded version.


Sildenafil, known as the generic version of Viagra, offers a more affordable alternative to the branded drug. It is equally effective in treating erectile dysfunction, as both Viagra and its generic form contain sildenafil citrate as the active ingredient.

Sildenafil is approved for treating erectile dysfunction (ED) in men aged 18 years and older. However, some men with pre-existing health conditions or those taking specific medications may not be suitable candidates for sildenafil. Your healthcare provider affiliated with Rizz will assess your suitability for sildenafil after you complete a complimentary online evaluation.

Sildenafil is an as-needed medication you can take when you want to be ready for sex. Here are some helpful tips:

  1. Test it solo first. Try your medication without a partner first so you see how it affects you/your body.

  2. Take at least 60 minutes before sex. Your medication stays in the body for approx. 4-6 hours.

  3. Works best on a close to empty stomach. Avoid fatty food and alcohol prior to using treatment.

  4. Arousal required. Sildenafil won’t automatically give you an erection if you’re not aroused, so start with foreplay to see the best results.

The most common side effects of sildenafil reported by Rizz members include: stuffy/runny nose, flushing, headaches, heartburn, dizziness, muscle aches, and nausea.

What safety information should I know before taking sildenafil?

Do not take sildenafil if you take any medicines called nitrates, often prescribed for chest pain, or guanylate cyclase stimulators like Adempas (riociguat) as this can result in a sudden, dangerous drop in blood pressure. Learn more

Why sildenafil?


Stronger, longer-lasting erections
Sildenafil blocks an enzyme called PDE5, which makes it easier for blood to flow to the penis for a harder erection.


Taken before sex
Sildenafil is an ED medication that’s taken orally when you want to be ready for sex. When used as directed, it works within 30-60 minutes.


Lasts 4-6 hours
Sildenafil stays in the body for 4-6 hours, during which time a person has an easier time getting and maintaining an erection. But don’t worry, it doesn’t cause arousal, so you’ll only get erect when you’re in the mood. That means when the time is right, turn up the romance (and foreplay!).

FAQ: Sildenafil

Sildenafil is a short acting medication with a rapid onset. Remember that sildenafil will not give you a spontaneous erection without sexual stimulation. It should be taken 30–60 minutes before sex, and it reaches peak blood levels in 60 minutes on average.

Sildenafil is a short acting drug with an average half-life of 4–5 hours, which means that half the medicine is gone from the body after 4–5 hours in healthy people. But just because the drug stays in your body for hours doesn’t mean your erection should last that long. Sildenafil (and other ED treatments) will not give you an erection for the entire period that they are in your system and your erection will still go down as normal after ejaculation.

Sildenafil is one of the medications offered on our platform. To determine which medication might be right for you, it’s best to complete the online visit and connect with a US-licensed healthcare provider to further discuss your options. If prescribed, your medication will be mailed directly to your door in discreet packaging.

Generic forms of Viagra® are safe when taken as prescribed. The generic of Viagra® has the same active ingredient (sildenafil citrate) as branded Viagra®. While the appearance of the pills may differ, the active ingredient acts the same way and produces the same results in the body. Before you get a prescription for the generic of Viagra®, your healthcare provider will check if you have any underlying health conditions and if you’re taking certain other medications that could make the generic of Viagra® less safe for you.

Sildenafil should be taken 30–60 minutes before sex. It’s important to take it without a meal because fat in a meal can decrease and delay its absorption, which can lower sildenafil’s effectiveness. Even though the instructions are to take it 30–60 minutes before sex, sildenafil lasts in the body for up to 6–8 hours.
