Safely Buy Viagra ( Sildenafil ) from Canada Prescriptions Plus.

Indications

Viagra is a medication used to treat erectile dysfunction in men.

Sildenafil is a phosphodiesterase 5 (PDE5) inhibitor with smooth muscle relaxation and vasodilation effects that help treat erectile dysfunction. Another brand of sildenafil is used to treat hypertension thanks to its ability to increase blood flow.

This medication is generally well-tolerated with a lower incidence of adverse effects. When taken orally, Viagra is also easily absorbed so it can start working quickly.

Cautions

Avoid drinking alcohol while taking Viagra to avoid an increase in adverse effects.

Avoid grapefruit or grapefruit juice; this may interact with sildenafil and cause unwanted side effects.

Don’t use any other medication for impotence such as alprostadil or yohimbine without first consulting your doctor.

Some medications may interact with sildenafil and can cause unwanted or dangerous effects. Tell your doctor about all the medications you take, including over the counter, vitamins, and herbal products, but especially nitrates and riociguat.

Tell your doctor if you use any of the following medications:

• Drugs for high blood pressure or a prostate disorder
• Antibiotics (clarithromycin, erythromycin, or telithromycin)
• Antifungal medicine (ketoconazole or itraconazole)
• HIV/AIDS medication (atazanavir, indinavir, ritonavir, or saquinavir)

• Medications for pulmonary artery hypertension

Do not take Viagra if you use a nitrate drug for chest pain or heart problems because they can cause your blood pressure to drop suddenly. These drugs include nitroglycerin, isosorbide dinitrate, and more.

If you have an erection that is painful or lasts longer than 4 hours, contact your doctor immediately. A prolonged erection can damage the penis.

Stop using Viagra and seek immediate medical attention if you have a sudden loss of vision.

To ensure this medication is safe for you to take, tell your doctor if you have ever had any of the following:

Sildenafil can decrease the blood flow to the optic nerve in your eye which can cause sudden vision loss. This is a rare effect that has happened in a few people who also had heart disease, diabetes, high blood pressure, high cholesterol, or pre-existing eye problems in those 50 years or older as well as those who smoked.

While having sex, if you become dizzy or nauseated, or have pain, numbness, or tingling in your chest, arms, neck, or jaw, stop and call your doctor, these could be signs of a serious sildenafil side effect.
