Viagra 100 Mg

Important information

Some medicines can cause unwanted or dangerous effects when used with viagra 100mg. Tell your doctor about all your current medicines, especially riociguat (Adempas).

Do not take viagra 100mg if you are also using a nitrate drug for chest pain or heart problems, including nitroglycerin, isosorbide dinitrate, isosorbide mononitrate, and some recreational drugs such as “poppers”. Taking sildenafil with a nitrate medicine can cause a sudden and serious decrease in blood pressure.

Contact your doctor or seek emergency medical attention if your erection is painful or lasts longer than 4 hours. A prolonged erection (priapism) can damage the penis.

Stop using Viagra and get emergency medical help if you have sudden vision loss.

Before taking this medicine

You should not use Viagra if you are allergic to sildenafil, or:

• if you take other medicines to treat pulmonary arterial hypertension, such as riociguat (Adempas).

Do not take viagra 100mg if you are also using a nitrate drug for chest pain or heart problems. This includes nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate. Nitrates are also found in some recreational drugs such as amyl nitrate or nitrite (“poppers”).

Taking viagra 100mg with a nitrate medicine can cause a sudden and serious decrease in blood pressure.

To make sure Viagra is safe for you, tell your doctor about your other medical conditions, especially:

• heart disease or heart rhythm problems, coronary artery disease;
• a recent history (in the past 6 months) of a heart attack, stroke, or congestive heart failure;
• high or low blood pressure;
• liver or kidney disease;
• a blood cell disorder such as sickle cell anemia, multiple myeloma, or leukemia;
• a bleeding disorder such as hemophilia;
• a stomach ulcer;
• retinitis pigmentosa (an inherited condition of the eye);
• a physical deformity of the penis (such as Peyronie’s disease); or
• if you have been told you should not have sexual intercourse for health reasons.

Viagra can decrease blood flow to the optic nerve of the eye, causing sudden vision loss. This has occurred in a small number of people taking sildenafil, most of whom also had heart disease, diabetes, high blood pressure, high cholesterol, or certain pre-existing eye problems, and in those who smoked or were over 50 years old. It is not clear whether sildenafil is the actual cause of vision loss.

Tell your doctor if you are pregnant or plan to become pregnant.

It is not known whether sildenafil passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

Do not give Viagra to anyone under 18 years old without medical advice.
