What is Viagra?
Viagra is an oral prescription medication that is FDA-approved to treat erectile dysfunction (ED) in males aged 18 years and older.
Viagra contains the active ingredient sildenafil, which belongs to a class of drugs known as PDE5 inhibitors. Sildenafil works by increasing blood flow to the penis, helping individuals maintain a firm erection. However, it's important to note that Viagra only works when sexual arousal is present.
Numerous studies have shown Viagra to be effective for improving erectile function. If you're struggling with ED, have a discussion with your doctor about whether Viagra could help. They can determine if it's a good match for your symptoms.
When you're ready to fill your Viagra prescription, consider using a reputable online Canadian pharmacy like My Drug Center. Online Canadian pharmacies can offer savings of up to 90% on brand name Viagra compared to U.S. pharmacies.
How Does Viagra Work?
Getting aroused sets off a chain reaction in your body. Your nerves release nitric oxide, which boosts blood flow to the penis. The increased blood flow causes the penis to become erect.
However, eventually, a chemical called phosphodiesterase type 5 (PDE5) reverses the process, causing you to lose the erection.
This is where Viagra comes in. Viagra contains sildenafil, which belongs to a class of drugs called PDE5 inhibitors. These drugs work by blocking PDE5 so the erection can last longer.
It's important to understand that Viagra doesn't give you an erection - it only maintains the erection. You still need to become aroused on your own for Viagra to work.

Viagra Dosages
Viagra comes in tablet form and is taken orally. It is available in three different strengths: 25 mg, 50 mg, and 100 mg.
The typical recommended dose of Viagra for erectile dysfunction is 50 mg. You should take this dose about an hour before you plan to engage in sexual activity. Viagra works best when taken 30 minutes to four hours ahead of sex, but for most men the optimal time is one hour before.
It is important not to take Viagra more than once per day. Taking too much Viagra in a single day can increase the likelihood of side effects such as headaches, indigestion, dizziness, fainting, and painful erections.
FAQs
How long does it take Viagra to work?
When you take Viagra, it can take 30 minutes to one hour for the medication to start working properly. This is the time needed for the drug to absorb into your bloodstream to take full effect. To ensure Viagra works on time, it's best to avoid eating fatty or heavy meals around the time you take your tablet. Fatty foods can slow down the absorption of Viagra.
How long does Viagra last?
Viagra typically lasts for two to three hours before it starts to wear off. However, depending on your metabolism and dosage, Viagra can stay in your body for five hours or more.
Can I combine Viagra with other ED medications?
No, erectile dysfunction medications should not be combined. ED medications work by relaxing blood vessels to increase blood flow, which can lower blood pressure. Combining multiple ED medications can result in a dangerous drop in blood pressure.
If you feel the need to take more than one ED medication, your dosage may be too low for you. Talk to your doctor about adjusting your dosage for more effective results.
Can I drink alcohol with Viagra?
It’s important to be cautious when mixing Viagra and alcohol. Both substances relax and widen your blood vessels, which lowers your blood pressure. When combined, their effects are amplified, causing your blood pressure to decrease more substantially than if you consumed either one alone.
If avoiding alcohol is not possible, limit your intake to one or two drinks. The effects of Viagra can last up to five hours, so keep this timeframe in mind if you do have alcohol.
