Viagra is the brand name for the drug Sildenafil. Sildenafil is a type of medication used to treat erectile dysfunction, a condition where men find it difficult to get or maintain an erection.

Viagra works by increasing blood flow to the penis so you can get and keep an erection.

You can take Viagra as needed although you should only use it once in any 24 hour period. Viagra is available as a pill in 25mg, 50mg and 100mg, depending on what you and your doctor determine to be most suitable for your needs.

Usually, Viagra will start to work within 30 to 60 minutes. If you’re wondering when to take Viagra, you can take it up to four hours before sexual activity.

Viagra is not a treatment for premature ejaculation, so it usually won’t impact the amount of time you can have sex for before you ejaculate.

Viagra won’t make you hornier or help you feel sexually aroused when you otherwise wouldn’t be interested in sex. Viagra simply makes it easier to get an erection when you’re already sexually aroused.

If you have erectile dysfunction and normally find it difficult to get or maintain an erection, Viagra might cause your erection to feel bigger but it will not make your penis physically larger than its regular size.

Common Viagra side effects include flushing, lightheadedness, headache, runny nose, or nausea.

If you develop an erection that lasts longer than 3 hours please go to the emergency department - this is a rare but dangerous side effect called priapism.

There have been exceedingly rare reports of non-arteritic anterior ischemic optic neuropathy - a condition that impacts sight - although most experts do not believe this to be related to ED medications.

It is recommended that you see a doctor in person for this issue, for a full physical exam and blood work to determine if there is an underlying cause like diabetes, vascular disease or low testosterone

Viagra isn’t for everyone. You should not take Viagra if any of the following conditions apply to you:

• You have previously experienced an allergic reaction to sildenafil (Viagra) or any other medicines in the past
• You are taking medicines called nitrates for chest pain
• You are currently taking take any guanylate cyclase stimulators, like riociguat (adempas)
• You are using drugs such as amyl nitrate or amyl nitrite, and butyl nitrate, also known as poppers. 
• You have a serious liver or heart problem
• You have low blood pressure or a condition that may lower blood pressure like aortic stenosis or hypertrophic obstructive cardiomyopathy
• You have recently had a heart attack or stroke
• You are taking other medication for erectile dysfunction, such as Cialis.

In Canada, Viagra is not available over the counter, so you will always need a prescription from a doctor first.

If you are experiencing the symptoms of erectile dysfunction and are seeking a prescription for Viagra, talk to a doctor about whether it is the right solution for you.

There are other medication options besides Viagra such as Tadalafil, also known as Cialis.

Beyond medication, consider addressing potential lifestyle causes of erectile dysfunction, including diet, alcohol consumption and exercise levels.

Yes, Viagra does expire. Once a year has passed since your prescription was dispensed, the Viagra is considered to have expired. After this time it starts to become less effective, and is therefore not recommended.

The difference between Cialis and Viagra and other ED medications is that it tends to be longer lasting. While Viagra works for three to five hours, a typical dose of Cialis keeps working for 24 to 36 hours in your body.

To get Viagra pills in Canada you need a prescription from a healthcare practitioner. You can get that from your family doctor, or if you don’t have one you can get a prescription online from Felix. Getting a prescription from Felix is simple and you don’t have to deal with waiting rooms or pharmacy lines. All you need to do is create a Felix account, complete your medical profile information, and fill out a medical assessment. A healthcare practitioner will review your assessment and approve or deny your request for Viagra based on your medical profile. You’ll also have the chance to ask them questions about Viagra and have access to 24/7 secure messaging any time you need to talk to them.

To get a prescription for Viagra you’ll need to talk to a healthcare practitioner who can assess your situation and write the prescription. In Canada, only licensed healthcare practitioners are legally allowed to write prescriptions. Your family doctor can do this, or you can use an online health provider like Felix and get your prescription online, without having to visit the doctor’s office. Since Viagra and other PDE5-inhibitors are safe and widely used, you shouldn’t have any issues getting a prescription if you’re experiencing symptoms of erectile dysfunction. The most common symptoms of ED are difficulty getting an erection and difficulty maintaining a firm enough erection for long enough to have a satisfying sexual encounter. Once your prescription is written, you can go to a pharmacy to get it filled. If you’re using an online healthcare provider like Felix, it’s even easier. You can skip the pharmacy and order your Viagra online. It’ll be delivered to your home discreetly and on a schedule that works for you, so you’ll never be without it when the mood strikes.

You can buy Viagra online through an online healthcare provider like Felix. As it is a prescription drug that is not available over the counter, you can’t order it at regular retail stores. Since many people take Viagra only occasionally as it’s needed, it can be easy to forget that you need to buy more and find yourself in a situation where you wish you had it. Instead of ruining the mood by interrupting date night to go to a pharmacy, you can have Viagra regularly delivered to your doorstep so that you always have it when you need it. Buying it online not only helps you avoid running out when you need it most, but it also saves you the first trip to the doctor to get your prescription and the second trip to the pharmacy to get it filled. If you see other pills online that don’t require a prescription but that claim to have benefits similar to Viagra for those suffering from symptoms of ED, it’s a good idea to skip those. There are lots of unregulated products online, and some of these may not be safe. If you’re buying Viagra online, make sure you're buying it from Felix or another platform that adheres to all Canadian regulations, where licensed healthcare practitioners write prescriptions and registered pharmacists fill them.
