Viagra: What You Need to Know

Viagra, a well-known medication prescribed for erectile dysfunction (ED), has been a pivotal development in the field of men’s health since its approval by the FDA in 1998. Known generically as sildenafil citrate, Viagra helps men with ED achieve and maintain an erection suitable for sexual activity. This article provides a comprehensive overview of Viagra, including its usage, mechanism of action, recommended dosages, and potential side effects.

What is Viagra?

Viagra is a prescription medication used primarily to treat erectile dysfunction, a condition characterized by the inability to achieve or maintain an erection sufficient for satisfactory sexual performance. It belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. These medications work by increasing blood flow to the penis, aiding in the natural process of arousal.

How Does Viagra Work?

When a man is sexually stimulated, the body releases nitric oxide in the penis. This compound activates an enzyme, guanylate cyclase, which increases levels of cyclic guanosine monophosphate (cGMP). This chemical relaxes smooth muscle cells, allowing blood to flow into the penile tissues, leading to an erection.

Viagra enhances this process by inhibiting the PDE5 enzyme, which breaks down cGMP. By doing so, it ensures that cGMP levels remain high, facilitating prolonged blood flow and a sustained erection. However, Viagra will not cause an erection without sexual arousal.

Indications for Use

Viagra is primarily indicated for erectile dysfunction in men. It is important to note that Viagra is not an aphrodisiac and does not increase sexual desire. It is only effective when accompanied by sexual stimulation.

How to Use Viagra

– Dosage: The recommended starting dose for Viagra is 50 mg, taken as needed approximately 1 hour before sexual activity. However, it can be taken anywhere from 30 minutes to 4 hours prior to intercourse. Depending on effectiveness and tolerance, the dose may be increased to 100 mg or decreased to 25 mg.
– Administration: Viagra should be taken orally with water. It can be consumed with or without food, though a high-fat meal may delay its onset of action.
– Frequency: It should not be used more than once daily.

Possible Side Effects

Like all medications, Viagra can cause side effects, although not everyone experiences them. Common side effects include:
– Headache
– Flushing
– Indigestion
– Nasal congestion
– Dizziness
– Visual disturbances (such as changes in colour vision)

In rare instances, more severe side effects may occur, such as priapism (a prolonged and painful erection), sudden vision loss, or hearing loss. If any of these occur, seek medical attention immediately.

Interactions and Precautions

– Drug Interactions: Viagra can interact with certain medications, especially nitrates (used for chest pain) and some antihypertensives. Such interactions can lead to a dangerous drop in blood pressure.
– Precautions: Individuals with cardiovascular conditions, liver or kidney impairment, or those who have had a recent stroke or heart attack should consult a healthcare provider before using Viagra.
