It is essential to understand how to stay safe to prepare yourself for if you buy Viagra online in Canada.


How Is Viagra Normally Prescribed?

Viagra is prescribed to treat erectile dysfunction or impotence. Most men start with a 50 mg dose that’s taken around 1 hour before sexual activity. Viagra should work well anywhere from 30 minutes to 4 hours before having sex. 


Viagra should only be taken one time a day. You can take your pill with or without food. 

Standard Viagra Dose Adjustments

Depending on your reactions to this medication, your dosage might be raised to 100 mg or lowered to 25 mg. For example, patients over 65 years old or with liver or kidney issues may start with the 25 mg dosage.


Your dose may also need to be adjusted based on specific health situations or drug interactions. Tell your doctor if you take any of the following medications:

  • Nitrates
  • Alpha-blockers
  • Ritonavir
  • CYP3A4 inhibitors
  • GC stimulators

Common Viagra Side Effects

Like any medication, Viagra may cause side effects in some patients. These side effects are rare but can be severe. If you experience any severe symptoms, you should stop using Viagra and contact your doctor.

Cardiovascular Effects From Viagra

Viagra works by increasing blood flow and circulation throughout the body. This effect makes it easier to gain an erection, but it can also impact your cardiovascular system. Therefore, you should only take Viagra if you’re healthy enough to have sex. Patients with pre-existing heart or lung problems can be at risk when taking Viagra. 

If you have one or more of the following conditions, you may not be an excellent candidate to take Viagra:

  • A heart attack (myocardial infarction), stroke, or life-threatening arrhythmia within the past six months
  • High blood pressure
  • Low blood pressure
  • Unstable angina due to cardiac failure or coronary artery disease
  • Left ventricular outflow obstructions (aortic stenosis or idiopathic hypertrophic subaortic stenosis)
  • Impaired autonomic blood pressure control

Prolonged Erections Due To Viagra

In some cases, Viagra can cause lengthy or painful erections. A prolonged erection is an erection that lasts for four hours or longer. Priapism is a painful erection lasting six hours or longer. If you have an erection that lasts for four hours or more, you should immediately seek medical treatment. These conditions can damage the tissues of your penis and cause permanent impotence.

Ask your doctor if Viagra is safe if you have any of the following conditions:

  • Angulated penis
  • Cavernosal fibrosis
  • Peyronie’s disease
  • Other anatomical deformations of the penis
  • Sickle cell anemia
  • Multiple myeloma
  • Leukemia

Viagras Impact On Your Vision

Viagra can cause sudden vision loss in some rare circumstances. This can signify non-arteritic anterior ischemic optic neuropathy (NAION), a rare condition leading to decreased vision due to reduced blood flow to the optic nerve. Some patients experience permanent vision loss. If you’ve already experienced NAION, you’re more likely to have a recurrence when taking Viagra.

Viagra And Hearing Loss

Sudden hearing loss is another slight possibility when taking Viagra. Doctors don’t understand why Viagra can cause hearing loss, but some patients have reported this concern. You might also experience tinnitus, ringing in the ears, or dizziness. Contact your doctor if you notice any of these symptoms while using Viagra.

Low Blood Pressure And Viagra

Viagra can cause your blood pressure to drop. This drop can be a problem in patients who already have hypotension, low blood pressure, or take medicine to lower their blood pressure. If you feel dizzy or lightheaded while using Viagra, you should contact your doctor.

Basic Information For Viagra Patients

What Is Viagra?

Viagra is a prescription medication that treats erectile dysfunction. Viagra makes it easier for men to get an erection when sexually stimulated. This medicine won’t give you an erection on its own. Viagra is not for use by women or children.

What Are The Most Important Things To Know About Taking Viagra?

Viagra can make your blood pressure drop to a dangerous level, especially if you take Viagra in combination with other medications. For example, you should never take Viagra if you take a type of medicine called nitrates. Nitrates treat chest pain or angina. If your blood pressure drops while on Viagra, you could become dizzy, pass out, or have a heart attack or stroke.

Don’t take Viagra if you’re also taking medications called guanylate cyclase stimulators. This medicine class includes treatments for high blood pressure, such as Riociguat or Adempas.

Tell Your Entire Medical Team That You Take Viagra

Healthcare is a team effort. Tell all of your providers that you take Viagra. This includes doctors, nurses, pharmacists, dentists, physical therapists, EMTs, emergency doctors, and anyone who treats you. Viagra is safe when you use it carefully, but it can also cause serious side effects if you take it with other drugs. Your medical professionals can give you the best treatment when they know your whole medical situation.

If you have a medical emergency or heart problems, your healthcare providers will need to know the last time you took a Viagra dose.

Know When To Get Help

Sexual activity puts strain on your heart that can be risky if you’re recovering from heart disease. Contact your doctor or call for emergency assistance if you experience chest pains, nausea, or dizziness while having sex. 

Viagra doesn’t protect you from sexually transmitted diseases or accidental pregnancy. Talk to your partner about reducing risks by making safer sexual choices.

Who Should Not Take Viagra?

Don’t take Viagra if you also:

  • Take nitrate medications
  • Use street drugs known as “poppers”
  • Take guanylate cyclase stimulators

  • Had an erection lasting more than four hours

  • Guanylate cyclase stimulators
  • Alpha-blockers

How Do I Take Viagra?

Follow your doctor’s instructions. Your prescription will have information specific to you, so pay attention to the details. Your doctor will tell you how much Viagra to take and when to take it. If your dosage doesn’t give you the best results, your doctor may change the amount.

Generally, most men take Viagra one hour before sexual activity. However, you can take your dose between 30 minutes and four hours before having sex if desired. You can take Viagra with or without food. However, taking Viagra with a fatty meal may delay its impact.

Don’t take more than one dose of Viagra a day. If you take too much Viagra, call your doctor or go to the emergency room immediately.
