How Does Sildenafil Work?
Sildenafil is the active ingredient contained in most erectile dysfunction medications. It is best known for being the active ingredient in Viagra. However, it is today found in a variety of generic medications. Understanding how the medication works in treating erectile dysfunction (male impotence) could help you be more at ease when using it.

How sildenafil works?
Under the name Viagra, sildenafil is available in blue tablets. It is available in different dosages which range from 25 to 100mg. The doctor will prescribe the right dose based on your age, health, and other drugs you are using.

When using sildenafil, you need to swallow the tablet with a full glass of water. You should avoid taking alcohol or high fat meals before or after taking the medicine. Alcohol and high fat meals will hinder the absorption of the drug into the body. Take the recommended dose 30 minutes before engaging in sexual activity.

Sildenafil is quickly absorbed into the blood stream and you will start noticing the effects in 30 to 45 minutes. Sildenafil is a phosphodiesterase 5 inhibitor. It works by relaxing muscles in the walls of blood vessels. This increases the flow of blood to certain areas of the body. In this case, the drug will increase the flow of blood to the penis. This enables you to achieve a sturdy and long lasting erection. However, for this to happen, you will need sexual stimulation.

How to use the drug
All medications for treating erectile dysfunction are meant only for use in men with male impotence. Get a prescription first. Although the drug is not meant for use in women and children, it is not expected to cause harm to the unborn or breastfeeding baby. Use the drug when needed and as prescribed.

The tablets need to be swallowed with plenty of water at least 30 minutes before the planned sexual activity. For the oral suspension, shake the liquid thoroughly for at least 15 seconds before measuring the prescribed dose using a dose measuring cup or spoon.

Precaution
Sildenafil may cause dizziness, vision changes, and hearing changes. Report to your doctor any serious side effects like heart attack like symptoms and a painful erection or one lasting longer than 4 hours. If you feel nauseated or dizzy during sexual activity, or get any other heart attack like symptoms, stop the activity and seek emergency medical help. Never take more than one dose within 24 hours.
