Viagra Knock Off

What You Should Know About Viagra

Viagra (sildenafil) is an oral medication that treats erectile malfunction in men. It works by blocking certain naturally occurring enzymes in the body, causing blood vessels to dilate and improve blood flow to the penis.

It takes an hour for the drug to work, but it will only help you if you are sexually aroused. It must be taken on an unfilled stomach as a fatty food can slow down the drug’s absorbtion.

Dosage

Viagra is a unique medication that only works when you are sexually aroused. The medication helps with the muscle movements needed to create and sustain an erection by increasing blood flow through the penis, or corpora cavernosa.

It begins to work about an hour after taking the tablet. However, it can take longer or less time depending on what you eat. You typically only take Viagra once a day, and it works best when taken about an hour before sex.

Your doctor will probably start you on 25mg of Viagra, which is the lowest dosage for most people. It’s the lowest dose that has been proven effective in clinical studies. The lower dosage may reduce the risk of side-effects, such as visual disturbances or a blue haze. You can also choose this option if you suffer from health conditions or are taking drugs that interact negatively with Viagra.

Side effects

Besides helping men get and keep an erection, Viagra also helps blood vessels around the body to relax. This can help with heart conditions like angina pectoris, a type of chest pain caused by cardiovascular problems.

In some cases, Viagra can cause mild side effects such as headache or a runny or blocked nose. It can also make you feel dizzy or lightheaded. If this happens, you can either lie down or remain seated until your symptoms improve.

Viagra may not be safe for you if you have certain health problems, such as blood cell disorders (such as sickle cell anemia or multiple myeloma), or a history of Peyronie’s disease. It can also be dangerous if you take nitrate medications such as nitroglycerin for chest pain or high blood pressure. The pill’s effectiveness can be affected by consuming a fatty food, and alcohol can reduce the duration of the effect. Talk to your doctor before you take this medication.

Precautions

Taking Viagra can cause a sudden drop in blood pressure that can make you feel dizzy or faint. This is more likely to happen if you combine Viagra with certain drugs that treat high blood pressure, enlarged prostate or alcohol. Talk to your doctor if you have these conditions before taking Viagra.

You should also avoid drinking a lot of alcohol while taking Viagra. Some side effects, such as flushing and headaches, can be made worse by alcohol.

You should not take Viagra if you have a heart condition or a history of stroke, or if you are taking nitrate drugs (such as nitroglycerin or isosorbide dinitrate/mononitrate, used to treat chest pain). Nitrates can block the action of Viagra. This medication can also cause a long-lasting and painful erection, called priapism. Priapism may damage your penis, resulting in permanent ED.

Other Drugs

If a person takes Viagra for a long period of time, it may affect their ability to induce an erection naturally. This can lead to a psychological dependence on Viagra, and a desire for it to be taken even when there isn’t a sexual need. This can also lead to relational problems and distress.

Viagra should not be taken by people who have certain eye conditions such as non-arteritic anterior ischemic optic neuropathy (NAION) or hereditary retinitis pigmentosa because it can cause sudden loss of vision in one or both eyes. It should be used with caution by people who have low pressure, as it can cause blood pressure to drop to unsafe levels.

Other medications, including over-the-counter drugs such as ibuprofen and alpha-blocker medication such as doxazosin and terazosin (used to treat high blood pressure and a condition called benign prostatic hyperplasia), can interact with Viagra. These interactions can lead to a decrease in the effectiveness of the medication or can cause side effects.
