Viagra 100mg is a medication that is used in treatment of erectile dysfunction also referred as male impotence. It assists a person to attain and maintain erection that is sufficient for sexual activity. It works by enhancing the flow of blood into the penis when a man gets aroused sexually. It only works perfectly with sexual stimulation and it does not boost sexual desire. This medicine can be available in different names or in many different forms. It is good to note that the medication may not be effective in treating all the conditions. Your doctor may recommend you to take this drug depending on the condition you might be suffering from and fail to recommend it to others. If you have not discussed this with your doctor and you are not sure why you are taking it, you need to take more advice. If you are already taking it, you should never stop before you consult your doctor. You should also not give this drug to anyone else even if they are suffering from similar symptoms like yours. It can cause side effects if it is taken without the prescription of the doctor.
How to use
You are supposed to take Viagra 100mg approximately thirty to sixty minutes before sexual activity. However, it can be taken any time from four hours to thirty minutes before sexual intercourse. Depending on effectiveness and the side effects, you can decrease the dosage to 50mg to 25mg. You are not supposed to take it more than one dose in a day. It can be taken with or without food.
