Sildenafil brand name: the direct answer
Viagra
Viagra is a brand-name version of sildenafil. It is FDA-approved to treat erectile dysfunction (ED).
Revatio
Revatio is another brand-name version of sildenafil. It is FDA-approved to treat pulmonary arterial hypertension (PAH), which is high blood pressure in the lungs.
Generic sildenafil
Sildenafil is also sold as an FDA-approved generic medication. A generic is the same active ingredient as the brand, but it is not itself a brand name.
How the brand name changes what you see
| Name you may see | Active ingredient | What it is labeled for | What this means for you |
|---|---|---|---|
| Viagra | Sildenafil | Erectile dysfunction (ED) | If your prescription says Viagra, it is sildenafil intended for ED use per the label. |
| Revatio | Sildenafil | Pulmonary arterial hypertension (PAH) | If your prescription says Revatio, it is sildenafil intended for PAH use per the label. |
| Sildenafil (generic) | Sildenafil | Depends on the prescription | If it says sildenafil without a brand, it is the generic name. Your clinician specifies the intended use. |
Same drug, different labeled use
Viagra and Revatio contain the same active ingredient, sildenafil, but they are marketed and labeled for different conditions. That is why the brand name can signal what the prescription is intended to treat.
Do not mix with nitrates
Sildenafil is a PDE5 inhibitor that can lower blood pressure. Using it with nitrates (often used for chest pain) is contraindicated because it can cause a large drop in blood pressure.
Tell your clinician about alpha-blockers
Some medicines for prostate symptoms or blood pressure (alpha-blockers) can also lower blood pressure. Sildenafil may add to that effect, so your clinician may adjust timing or dosing and monitor symptoms.
Avoid certain ED combinations
Do not take sildenafil with other PDE5 inhibitors (for example tadalafil or vardenafil) unless a clinician specifically directs it. Combining similar medicines can increase side effects such as low blood pressure.
ED can be a health signal
Erectile dysfunction can sometimes be linked with cardiovascular disease risk factors. If ED is new, worsening, or comes with chest pain or shortness of breath, it is worth discussing a broader health evaluation with a clinician.
When to talk to a clinician
Chest pain or nitrate use
If you use nitrates for chest pain or have chest pain with sexual activity, do not take sildenafil unless a clinician has specifically evaluated you. Seek urgent care for chest pain or severe symptoms.
Fainting or severe dizziness
Sildenafil can lower blood pressure. If you have episodes of fainting, severe dizziness, or very low blood pressure, ask a clinician whether sildenafil is safe for you and whether other medicines could be contributing.
Vision or hearing changes
Sudden vision loss or sudden decrease or loss of hearing has been reported with PDE5 inhibitors and needs urgent medical evaluation. Do not ignore these symptoms.
Painful or prolonged erection
An erection that is painful or lasts longer than 4 hours is a medical emergency because it can damage penile tissue. Get emergency care right away.
Multiple medical conditions or medicines
If you have heart disease, liver or kidney disease, or you take multiple prescription medicines, a clinician can help confirm whether sildenafil is appropriate and how to use it safely.
Pro tips for searching and comparing names

Check the indication
Viagra is labeled for ED; Revatio is labeled for PAH.
Confirm interactions
Always mention nitrates, alpha-blockers, and blood pressure medicines to your clinician.
Use one PDE5 inhibitor
Do not combine sildenafil with tadalafil or similar drugs unless directed.
