What are Viagra Tablets?
Viagra tablets are a medication used to treat erectile dysfunction (ED) in men. They contain the active ingredient sildenafil, which works by increasing blood flow to the penis, helping to achieve and maintain an erection. Viagra tablets should be taken orally about 30 minutes to an hour before sexual activity.
How does it work?
Viagra (sildenafil) works by relaxing the blood vessels in the penis, which allows more blood to flow into the area and helps to create and maintain an erection. Specifically, it inhibits the enzyme phosphodiesterase type 5 (PDE5), which breaks down cyclic guanosine monophosphate (cGMP), a chemical that is responsible for relaxing the smooth muscles in the penis and increasing blood flow. By blocking the action of PDE5, Viagra increases cGMP levels and enhances the effects of nitric oxide, a chemical that is naturally produced in the body and also helps to increase blood flow to the penis. However, sexual stimulation is still required in order for Viagra to work effectively.

How to take it?
Viagra tablets are typically taken orally, about 30 minutes to 1 hour before sexual activity. Here are some general guidelines for taking Viagra:
- Take the tablet with a full glass of water. You can take it with or without food, but it may take longer to work if taken with a high-fat meal.
- Follow the dosage instructions provided by your healthcare provider. The standard dose of Viagra is 50 mg, but it may be adjusted up or down based on individual response and tolerability. The maximum recommended dose is 100 mg per day.
- Do not take more than one dose of Viagra in a 24-hour period.
- Do not crush, chew, or break the tablet. Swallow it whole.
- Remember that sexual stimulation is still required in order for Viagra to work effectively.
If you have any questions or concerns about how to take Viagra, talk to your healthcare provider.
Side Effects
Like any medication, Viagra can cause side effects. Not everyone experiences side effects and their severity can vary, but some of the most common ones include:
- Headache
- Flushing (redness, warmth)
- Indigestion
- Nasal congestion
- Dizziness
- Blurred vision
- Rash
- Back pain or muscle pain

Most of these side effects are mild and go away on their own within a few hours. However, some people may experience more serious side effects, such as sudden vision or hearing loss, or an allergic reaction, which requires immediate medical attention. If you experience any of these symptoms, stop taking Viagra and seek medical help right away.
It's important to talk to your healthcare provider about your medical history and any other medications you are taking before using Viagra, as it can interact with certain drugs and may not be appropriate for everyone.

Precaution
