How Viagra gives you power
Viagra is a medication that enables you to have sexual relations again, because Viagra works with your body, your blood stream, to help your body produce an erection when you are sexually excited. Without being sexually excited Viagra is not going to change anything about your body.
Viagra is not for everyone
Ask your doctor if your heart is healthy enough for sexual activity.
If you are taking any medicines that contain nitrates – either regularly or as needed – you should never take Viagra. Keep in mind that if you take Viagra with any nitrate medicine or recreational drug containing nitrates, your blood pressure could suddenly drop to an unsafe level. You could get dizzy, faint, or even have a heart attack or stroke. Nitrates are found in many prescription medicines that are used to treat angina (chest pain due to heart disease) such as:
nitroglycerin (sprays, ointments, skin patches or pastes, and tablets that are swallowed or dissolved in the mouth);
isosorbide mononitrate and isosorbide dinitrate (tablets that are swallowed, chewed, or dissolved in the mouth).
