What is Viagra and how does it work?
Viagra is a medication that is used to treat erectile dysfunction (ED) in men. It works by increasing blood flow to the penis, which helps to achieve and maintain an erection. The active ingredient in Viagra is sildenafil citrate, which belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. These drugs work by inhibiting the action of PDE5, an enzyme that breaks down cyclic guanosine monophosphate (cGMP), a chemical that is responsible for dilating blood vessels in the penis. By inhibiting PDE5, Viagra helps to maintain the levels of cGMP, which promotes blood flow to the penis and helps to achieve an erection.
How does Viagra work in the body?
When you take Viagra, it is absorbed into your bloodstream and carried to your penis. Once there, it works by relaxing the smooth muscle cells in the walls of your blood vessels, which allows more blood to flow into your penis. This increased blood flow causes your penis to become erect. However, Viagra does not work on its own. You still need to be sexually aroused in order to achieve an erection.
Who can take Viagra?
Viagra is a prescription medication that is used to treat ED in men. It is not recommended for women or children. If you have a history of heart disease or are taking certain medications, such as nitrates, you should not take Viagra without first consulting your doctor. Additionally, if you have a history of vision problems or have been diagnosed with retinitis pigmentosa, a rare genetic disorder, you should also avoid taking Viagra.
When should you avoid taking Viagra?
You should avoid taking Viagra if you are taking any medications that contain nitrates, such as nitroglycerin, isosorbide dinitrate, or isosorbide mononitrate. These medications are often used to treat angina or chest pain, and they can cause a sudden drop in blood pressure when taken with Viagra. If you experience chest pain, dizziness, or nausea during sexual activity after taking Viagra, you should seek medical attention right away.
How to take Viagra for best results
Taking Viagra correctly is essential to achieving the best results. Here are some tips to help you get the most out of this medication:
Take Viagra on an empty stomach
Viagra is most effective when taken on an empty stomach. This is because food can interfere with the absorption of the medication, making it less effective. If you have eaten a heavy meal, you should wait at least two hours before taking Viagra.
Take Viagra at least 30 minutes before sexual activity
Viagra should be taken at least 30 minutes before sexual activity. This gives the medication enough time to be absorbed into your bloodstream and start working. However, Viagra can be taken up to four hours before sexual activity, so you have some flexibility in when you take it.
Avoid alcohol and grapefruit juice
Alcohol and grapefruit juice can interfere with the absorption of Viagra, making it less effective. If you plan to take Viagra, you should avoid drinking alcohol or consuming grapefruit juice.
Do not crush or chew Viagra tablets
Viagra tablets should be swallowed whole with a glass of water. Do not crush or chew the tablets, as this can interfere with the absorption of the medication.
Do not take more than one dose per day
Viagra should be taken no more than once per day. Taking more than one dose can increase your risk of experiencing side effects.
Recommended dosage for Viagra
The recommended starting dose of Viagra is 50 mg, taken 30 minutes to four hours before sexual activity. Depending on your response to the medication, your doctor may adjust your dose to 25 mg or 100 mg. You should not take more than 100 mg of Viagra per day. It is important to follow your doctor's instructions regarding the dosage and timing of the medication.
What to do if the recommended dose isn't effective?
If you find that the recommended dose of Viagra is not effective, you should talk to your doctor. They may need to adjust your dosage or try a different medication. It is important not to take more than the recommended dose of Viagra, as this can increase your risk of experiencing side effects.
What to expect after taking Viagra
After taking Viagra, you should expect to feel the effects within 30 minutes to an hour. The medication can last up to four hours, although the duration of the effects may vary depending on your individual response to the medication.
