Directions

Before taking Sildenafil, carefully review this leaflet to ensure your understanding of its usage, benefits, and potential risks. Always follow your doctor's instructions and refer to the information provided here for additional guidance.

Ingredients

The active ingredient in Sildenafil film-coated tablets is sildenafil, a member of the phosphodiesterase type 5 (PDE5) inhibitor class of medications. Each tablet contains 25 mg, 50 mg, or 100 mg of sildenafil (as the citrate salt), combined with other components to ensure safe and effective delivery.

Before taking Sildenafil, it's crucial to consider potential interactions and contraindications. Do not use Sildenafil if you are allergic to sildenafil or any of its ingredients. If you are taking nitrates or nitric oxide donors, have certain heart conditions, severe liver issues, or a history of stroke or heart attack, consult your doctor before use.

FAQs

Please read our FAQs page to find out more.

What is Sildenafil used for?

Sildenafil is used to treat erectile dysfunction (ED), commonly known as impotence, in adult men. It helps relax blood vessels in the penis, allowing increased blood flow when sexually aroused, which can lead to a firm and lasting erection.

Can I take Sildenafil if I have other medical conditions?

It's important to consult your healthcare provider before taking Sildenafil, especially if you have a history of certain medical conditions such as heart problems, kidney or liver issues, eye diseases, or seizures. Your doctor will help determine if Sildenafil is safe and appropriate for you.

Can I take Sildenafil with other medications I'm currently using?

Before using Sildenafil, inform your healthcare provider about all medications you are taking, including prescription and over-the-counter drugs. Some medications, particularly nitrates, nitric oxide donors, and certain HIV treatments, may interact with Sildenafil and could lead to adverse effects. Your doctor will guide you on potential interactions.

How quickly does Sildenafil work, and how long does its effect last?

The onset of Sildenafil's effect varies from person to person but usually occurs within 30 minutes to an hour after taking the tablet. The duration of its effect can also vary, but it generally lasts for about four hours. Remember, sexual stimulation is necessary for the medication to work.
