Viagra Online Canada: Uses and Dosage

What is Viagra?

Viagra is an oral medication used to treat erectile dysfunction (ED) in men. It belongs to a group of drugs called phosphodiesterase type 5 (PDE5) inhibitors, which work by increasing blood flow to the penis during sexual stimulation. Viagra is available in the form of a tablet, an oral suspension, or an oral solution. It comes in a blister pack, and is taken orally with or without food.

How does Viagra work?

Viagra works by increasing the levels of sildenafil citrate, a PDE5 inhibitor, in the body. It inhibits the enzyme phosphodiesterase type 5, which helps to relax the muscles and increase blood flow to the penis. This helps to achieve and maintain an erection during sexual activity. Viagra is usually taken on an empty stomach, and its effects can last up to 36 hours.

How to take Viagra?

Follow your doctor's instructions about the dosage and usage of Viagra. Swallow the tablet with a glass of water, and take the medication on an empty stomach. It can be taken with or without food, but avoid consuming heavy or fatty meals before taking it. The dose of Viagra can be adjusted depending on the individual's response and tolerance to the drug. The maximum recommended dose of Viagra is one tablet per day, and it should be taken only when needed.

How long does it take for Viagra to work?

Viagra usually starts to work within 30 to 60 minutes of taking it. However, it can take up to four to five hours for Viagra to work, depending on how well it works. It may take up to 6 hours for Viagra to become effective, so it's important to take the medication at the same time each day to maintain the effectiveness of the drug.

What side effects can Viagra cause?

  • Headaches

How long can it take for Viagra to work?

Viagra is typically effective for up to 36 hours after taking it. However, it can take up to 6 hours for Viagra to work, so it's important to take the medication at the same time each day to maintain the effectiveness of the drug.

How should Viagra be stored?

Store Viagra at room temperature, away from heat, moisture and light. Keep it out of reach of children. Viagra should be stored in a cool, dry place away from direct sunlight and heat.

Is there any drug interactions with Viagra?

Sildenafil (Viagra) vs. Tadalafil (Cialis®)

are similar medications, as both are phosphodiesterase type 5 (PDE5) inhibitors.

Both sildenafil and tadalafil take approximately 30 minutes to take effect.3 The duration of effect is what sets the two medications apart. Tadalafil has the longest life of any PDE5 inhibitor and can remain effective for 24 to 36 hours after ingestion. Sildenafil generally only remains effect for approximately four hours but can last up to 12 hours.

Sildenafil (Viagra®) vs. Avanafil (Stendra®)

What sets avanafil apart from sildenafil is the quicker action and lower risk of side effects.

Avanafil takes an average of 15 to 30 minutes to take effect, while sildenafil takes an average of 30 minutes. In a, avanafil showed a minor occurrence of side effects and negative interactions with other drugs.

A common side effect of all PDE5 inhibitors is reducing blood pressure. For some patients, this is a favorable side effect. However, for others, a drop in blood pressure could be dangerous. Avanafil has been shown to have less impact on blood pressure than sildenafil.

Tadalafil (Cialis®) vs.

Choosing between tadalafil and avanafil for erectile dysfunction comes down to choosing speed or endurance. Avanafil is one of the fastest-acting PDE5 inhibitors and takes approximately 15 to 30 minutes for effects to start with a six to 12-hour window of effectiveness. Tadalafil can take approximately 30 minutes to 45 minutes to fully kick in but can remain effective for 24 to 36 hours.

Cost is also a factor when comparing tadalafil and avanafil. Tadalafil has been available in generic forms since 2018 and is available at a lower price point than avanafil.

Vardenafil (Levitra®) vs. Sildenafil (Viagra)

Vardenafil and sildenafil are very similar PDE5 inhibitors with only slight variances. Vardenafil can take up to an hour to take effect, while sildenafil can kick in closer to 30 minutes after ingestion. Both medications generally last around four to five hours.

The main difference between these two ED medication options is the side effects. With sildenafil, some users reported a shift in color perception while under the drug’s influence. No users of vardenafil have reported this unusual side effect. One showed that vardenafil was slightly better tolerated than sildenafil. However, it was by a small margin.

As with many other PDE5 inhibitor comparisons, vardenafil and tadalafil are similar medications, with the main difference being the endurance of the drugs. Tadalafil effects last considerably longer and stay active for up to 36 hours. Vardenafil’s window of effectiveness is four to five hours.

The absorption of these two medications differs slightly as well.
