Sildenafil Citrate Information

SILDENAFIL (sil DEN a fil) is used to treat erection problems in men.

This medicine may be used for other purposes; ask your health care provider or pharmacist if you have questions.

Viagra® works to treat erectile dysfunction by improving blood flow to the penis. By taking Viagra®, you can get and keep an erection well enough to have sex. The medicine starts to work 30 to 60 minutes after taking the dose. Take the medicine only when you are about to have sex, but do not take more than one dose each day. Viagra® is not supposed to be taken every day as a routine medicine.

Take your dose up to 4 hours before sex and still get and keep an erection. Viagra® only starts to work when you are sexually stimulated. Viagra® works best if you take it on an empty stomach about an hour before sex. The effect lasts for as long as 6 hours after taking the dose.

Erectile dysfunction can be caused by many things, but most people have physical problems that cause their condition. Examples of physical conditions include heart disease, high cholesterol, high blood pressure, and diabetes. Anxiety, stress, smoking, and alcohol use, can also contribute to problems with sexual performance.

Before you start taking Viagra from a Canadian Prescription Referral Service or any pharmacy, talk to your doctor about all your medical conditions and stressors to see if you have an underlying problem that can be treated to correct your erectile dysfunction.

Other prescription drugs that treat erectile dysfunction include:

Some men cannot take the drugs, or the drugs may not work for them. As an alternative to buying Viagra online other treatments are available for men that cannot take medicines for erectile dysfunction.

A medicine called alprostadil is available as a self-injection and is marketed under two brand names, Caverject® and Muse®. Alprostadil is also made in a suppository form that is inserted into the penis. Do not mix Viagra® with alprostadil.

Other options to treat erectile dysfunction include testosterone replacement medications and penis pumps. Surgical options include penile implants and blood vessel surgery.

Besides treating erectile dysfunction, sildenafil can be used to improve exercise ability and delay worsening of symptoms in people that have some forms of pulmonary arterial hypertension. People with this illness take sildenafil on a regular basis, which is different than people that use this medicine for erectile dysfunction. The dose is also different in treating pulmonary arterial hypertension. The brand name for sildenafil for this use is called Revatio®.

Each Viagra prescription from our Canadian Prescription Referral Service comes with a printed medication guide. Always take time to read the medication information in the guide to be sure you are reviewing the most recent information about your medicine.

A less expensive and safe generic alternative to Viagra may be available. By using a Canadian Prescription Referral Service, we can help you find a licensed Canadian or international pharmacy that can provide you with safe generic products and the best possible dollar savings. As an added safety measure, we recommend purchasing your medicines from a pharmacy that is a member of the Canadian International Pharmacy Association.

Some drug interactions can be life-threatening. Other interactions can cause unwanted side effects or make the medicines more or less effective. Sometimes drug interactions can cause a medicine to exceed safe levels in the blood, similar to taking an overdose. This can happen all at once or gradually over time. A drug interaction happens when one drug causes another drug to change how it works in the body.

Many processes are at work in your body that handle drugs. Interactions can happen at different places and for different reasons. Some processes involve how your gut absorbs the medicine, others involve the way your liver works to alter medicines. Some interactions occur at the exact place in your body where the drugs connect to do their job, and others involve changes with the way the drug is eliminated from your body.

Viagra® is no exception. There are many medicines that interact with Viagra®, or sildenafil, including alcoholic beverages and herbal products like St John's wort.

Some examples of medicines that may become stronger when combined with Viagra® are listed here. This can mean that you may have side effects or an unwanted increase in the effect of the medication.

For you safety, the pharmacists at your Canadian Prescription Referral Service need to know about all your medicines. Be sure they have a complete list of prescription medicines, over-the-counter medicines, vitamins, supplements, and herbal products you take.
