Viagra® is a brand-name erectile dysfunction medication that became the first FDA-approved oral medication for ED in 1998. Viagra® is a PDE-5 inhibitor which helps to relax blood vessels and improve blood flow.
Always take Viagra® as instructed by your provider. It's typically recommended to take it about one hour before you plan to have sex. Beginning in about 30 minutes and for up to 4 hours, Viagra® can help you get hard if you are sexually excited. If you take Viagra® after a high-fat meal, the medicine may take a little longer to start working.

BMI stands for Body Mass Index. It’s a measurement that uses your height and weight to estimate if your weight is in a healthy range for your height.
*BMI doesn’t directly measure body fat and may not accurately reflect health for people with high muscle mass, pregnant women, children, older adults, certain ethnic groups, or those with medical conditions. It shouldn’t be used as the only way to assess health. The BMI calculator does not determine eligibility for weight loss medications. A healthcare provider must evaluate your overall health and history to decide if medication is right for you.

There are known drug interactions or contraindications with Viagra®, including the following drugs:
Other medications for ED, including Stendra® (avanafil), Cialis® (tadalafil), Levitra® (vardenafil) or other forms of Viagra®, such as sildenafil Revatio® or Adcirca®, two brand-name drugs used to treat pulmonary arterial hypertension. These medications are also PDE5 inhibitors and cannot be taken at the same time as Viagra®.
If you take any of the above medications, discuss your options with your doctor. If you are prescribed one of the above medications while taking Viagra®, tell your doctor.
Viagra® may be better for you and your sex life than other ED medications, but it is not inherently better or worse than other ED treatment options. If you want a drug that you can take as-needed and that works quickly and effectively during sexual stimulation, Viagra® might be right for you. If you want around-the-clock ED treatment, daily dosages of Cialis or Tadalafil might be right for you. Viagra® is a great ED option for many men, but the best ED medication is the one that is right for you.
The side effects most commonly associated with Viagra® include headaches, flushing, upset stomach, abnormal vision, runny or stuffy nose, muscle and back pain, nausea, dizziness, and rash. As always, if you have questions or any side effects that bother you or linger, talk to your provider. If you have an erection that lasts longer than 4 hours, get medical help immediately. See important safety information page for more details.
In general, Viagra® is safe when taken as prescribed. Viagra® was rigorously tested in clinical trials prior to FDA approval and now has over two decades of use by men around the world. However, if you have certain health conditions, such as cardiovascular or heart problems, heart failure, irregular heartbeat, heart disease or a recent heart attack, Viagra® may not be a safe option for you.
In addition, if you have high blood pressure, low blood pressure, multiple myeloma, sickle cell anemia, leukemia, retinitis pigmentosa, bleeding problems, stomach ulcers, kidney problems, liver problems or Peyronie’s Disease, disclose these conditions to your doctor to ensure that you are clear to take Viagra®.
Viagra® typically lasts in full effect for about two to three hours after you take the pill. Viagra® can work for up to four or five hours, but you will likely notice that its effectiveness starts to decrease after two or three hours. This is because the half-life of Viagra® is about four hours, which means that only half of the drug will still be in your system after that time, reducing its effect on your erection.
Keep in mind that Viagra® is typically not effective until about an hour after you take the drug, so you will need to plan ahead for sex. If you are looking for an ED drug that works around the clock, Cialis or Tadalafil might be the best option for you.
For most men, taking Viagra® 60 minutes before sexual activity is ideal, but some men experiment with different timing to see what works best. Because it’s taken as-needed, you don’t have to worry about remembering to take a pill every day—just when the moment is right. Be sure to follow your provider’s recommendation for best results.
Inhibits PDE5
Viagra® is an oral ED medication that works by suppressing an enzyme in the body called PDE5.
Increases blood flow
When PDE5 is suppressed, blood is able to flow more freely through the body—including to the (you guessed it) penis.
Gets you hard
More blood flow to the penis means harder, more satisfying erections once you’re sexually stimulated.
