Understanding Viagra: Uses, Dosages, and Side Effects

Viagra, the brand name for sildenafil citrate, is a well-known medication used to treat erectile dysfunction (ED) in men. First approved by the FDA in 1998, it has since become a staple in the treatment of ED. This guide aims to provide comprehensive information about Viagra, its uses, dosages, and potential side effects.

What is Viagra?

Viagra is a medication that falls under the category of phosphodiesterase type 5 (PDE5) inhibitors. It works by increasing blood flow to the penis, helping men achieve and maintain an erection during sexual activity. This effect is achieved by relaxing the blood vessels in the penis, allowing for improved circulation.

How to Use Viagra

– Consultation: It’s essential to consult a healthcare professional before starting Viagra. A doctor will evaluate your medical history and determine if Viagra is suitable for you.

– Dosage: Viagra is typically available in 25mg, 50mg, and 100mg tablets. The recommended starting dose is 50mg, taken as needed about one hour before sexual activity. Depending on efficacy and tolerance, the dosage may be adjusted.

– Administration: Take Viagra with water, with or without food. However, a high-fat meal may delay its effectiveness.

Mechanism of Action

Viagra works by inhibiting the PDE5 enzyme, which is responsible for regulating blood flow in the penis. By blocking this enzyme, Viagra enhances erectile function. This action only occurs with sexual stimulation, ensuring that erections are not spontaneous but rather occur in response to sexual arousal.

Indications for Use

Viagra is primarily indicated for the treatment of erectile dysfunction in men. It is not intended for use by women or children. Some off-label uses include treatment for pulmonary arterial hypertension, but this should only be pursued under a doctor’s guidance.

Possible Side Effects

Like any medication, Viagra may cause side effects. Common side effects include:

– Headaches
– Flushing
– Indigestion
– Nasal congestion
– Dizziness

Rare but serious side effects may include:

– Sudden vision loss
– Hearing loss
– An erection that lasts more than four hours (priapism)

If you experience any severe side effects, seek medical attention immediately.
