Viagra is a drug that relaxes the muscles found on the walls of the blood vessels to accelerate the blood flow to certain parts of the body. Normally, this treats erectile dysfunction in men. Since there are some medicines that can cause serious side effects when taken with Viagra, it is very important that you consult a doctor before using it. For instance, if you are on any drug for heart problems or chest pains, it is not advisable to use Viagra.
Before taking the drug it is important to share with your doctor about your medical history so that he can advise you whether to take it or not. This is because Viagra can also decrease the blood flow going to the optic nerves of the eyes making you partially blind.
How you should take it
When starting on the drug you should take it exactly as the doctor has prescribed it to you. Follow all the guidelines and do not take it for longer or shorter periods than recommended by the doctor. This is a very serious drug and should only be taken when it is needed. In fact, for it to work effectively you should always take it some 30 minutes before the sexual activity. When sexual stimulation occurs Viagra can help you get an erection. However, during the sexual intercourse if you become dizzy, numb or nauseated you should stop and call a medical expert immediately.
Side effects
Some of the side effects that you might experience after taking the drug include stomach upset, headache, and dizziness, among others. If you continue to experience any of these side effects you should immediately consult your doctor. However, to ensure that the effects are not too much, stand up slowly when rising from a sleeping or sitting position. The reason why it is important to consult a doctor is because he will prescribe the drug based on the benefits that you will get and not the side effects. This is why most people who have consulted a doctor do not experience any side effect.
In some instances, sexual activity may also cause a lot of strain on your heart. This is true especially when you have suffered from heart problems before. Ideally, before taking this medication, ensure that you ascertain that you are healthy. This will make you be on a safer side.
