What Is Sildenafil?
Sildenafil (generic Viagra) is a prescription medication used to manage erectile dysfunction. It works by inhibiting phosphodiesterase type 5 (PDE5), which relaxes smooth muscle in the blood vessels of the penis and increases blood flow during sexual stimulation. With the right dose and ongoing monitoring, most men can achieve reliable, satisfying results.

Is Online Sildenafil Treatment Right for You?
Doctronic can help you refill sildenafil for erectile dysfunction if you have an established diagnosis and have previously tolerated the medication. Our licensed physicians review your health history to confirm the refill is appropriate and safe for you.

Frequently asked questions
Sildenafil blocks the PDE5 enzyme, which normally breaks down a chemical called cGMP in penile tissue. By preserving cGMP levels, sildenafil allows the smooth muscle in penile blood vessels to relax and fill with blood during sexual stimulation, producing an erection.
Sildenafil is typically taken 30 to 60 minutes before sexual activity. Its effects generally last 4 to 6 hours. Taking it on a full stomach, especially a high-fat meal, can slow absorption and delay onset.
The most common starting dose is 50 mg, taken as needed. Depending on how you respond and tolerate the medication, your physician may adjust the dose to 25 mg or up to 100 mg. Do not change your dose without guidance from your provider.
Common side effects include headache, facial flushing, nasal congestion, indigestion, and temporary visual changes such as a blue-tinged tint. These are usually mild and short-lived. Seek immediate medical attention if you experience sudden vision or hearing loss, or chest pain.
Sildenafil must never be combined with nitrate medications (such as nitroglycerin or isosorbide) because the combination can cause a dangerous drop in blood pressure. Inform your physician of all medications, including alpha-blockers and blood pressure drugs, before starting or refilling sildenafil.
Sildenafil is generally not recommended for men with severe cardiovascular disease, recent stroke or heart attack, very low blood pressure, or certain hereditary eye conditions. A physician review ensures sildenafil is appropriate for your individual health situation.
