Getting aroused is the first step to an erection. When you become aroused, your nerves release nitric oxide, which increases blood flow to the penis. This rush of blood leads to an erection.

However, a chemical called phosphodiesterase type 5 (PDE5) eventually reverses this process and causes the erection to go away. This is where Viagra can help.

Viagra contains sildenafil, which blocks PDE5. By inhibiting this chemical, Viagra allows the blood flow to remain increased, keeping the penis erect for longer.

It's important to understand that Viagra doesn't give you an erection on its own - you still need to become aroused first. Viagra simply helps maintain the erection once it has started.

While most people tolerate Viagra well, some men may experience side effects. It's important to be aware of potential Viagra side effects, so you know what to watch out for.

Mild side effects of Viagra may include:

• Headache 
• Upset stomach
• Changes in vision, such as color variations or blurred vision
• Stuffy or runny nose 
• Nausea
• Dizziness
• Muscle aches and pain 

While these side effects are generally mild and temporary, it is important to note that Viagra can also cause more serious side effects, such as:

• An erection lasting over four hours
• Vision loss
• A decrease or loss of hearing

If you are currently experiencing side effects, you may be wondering, “how long do Viagra side effects last?” Fortunately, many side effects tend to subside within a few minutes to a few hours after taking the medication. However, if any side effects are bothersome or persist, it is recommended to seek medical attention.

When you take Viagra, it's important to be patient and allow adequate time for your body to absorb the medication. Typically, it can take 30 to 60 minutes for Viagra to start working properly after you've taken it.

Once Viagra starts working, you'll usually experience peak effects within 1 to 2 hours. The effects tend to last for 4 to 5 hours after taking Viagra. For most men, taking Viagra about an hour before sexual activity produces the best results. However, the exact timing can vary from person to person based on factors like your age, health condition, and metabolism.

The best place to buy Viagra online is through a reputable online Canadian pharmacy like Canada Pharmacy Depot.

Viagra can be quite expensive in the U.S., with just four 50 mg tablets costing around $400. In comparison, Canada Pharmacy Depot offers the same four 50 mg Viagra tablets for only $93.

Canada regulates prescription drug prices to keep them affordable for consumers. Because of this, online Canadian pharmacies can pass on huge savings to their customers.

Both Canada and the U.S. have strict rules to ensure all medications are safe and effective. Because of these thorough processes, you can feel confident that medications from Canada and the U.S. meet the highest standards of quality and safety.

Online Canadian pharmacies also offer generic Viagra for sale. Generic Viagra contains the same active ingredients as the brand-name version but at a much lower price. Generics go through the same strict approval process as brand-name drugs and are equally safe and effective.

It’s important to note that although brand-name Viagra is a diamond-shaped blue tablet, generic Viagra looks different. So, what does generic Viagra look like? Generic Viagra has the same formulation as brand-name Viagra, but it is a round white tablet.

Can you take Viagra and Cialis together?

The short answer is no, you should not take Viagra and Cialis together. While it may seem like taking them together could improve results, it can actually be quite dangerous.

Viagra and Cialis treat erectile dysfunction by relaxing blood vessels to increase blood flow to the penis. This causes your blood pressure to drop slightly. By combining ED medications, your blood pressure can drop to dangerous levels.

If you find that Viagra or Cialis alone is not effective enough for you, the solution is not to take both medications together. Instead, talk to your doctor about adjusting or switching your dosage or prescription. 

Where can I get Viagra?

If you're looking to purchase Viagra, you have a couple of options available to you: you can either head to a U.S. pharmacy or buy Viagra online through an online Canadian pharmacy like Canada Pharmacy Depot.

One of the benefits of buying from a reputable online Canadian pharmacy is the convenience factor- you can place your order entirely online and have your medication delivered right to your doorstep. But beyond that, there's also the added benefit of more affordable medications.

Canada has strict medication approval processes that are similar to those in the U.S., meaning that you can trust the quality and safety of the medications you're purchasing from a reputable online Canadian pharmacy. And with regulations in place that cap prescription drug prices at more reasonable rates compared to the U.S., online Canadian pharmacies can offer substantial savings to their customers.

How many beers can you have with Viagra?

When taking Viagra, it's best to limit your alcohol intake to one or two beers.

Viagra and alcohol both dilate blood vessels, lowering blood pressure. When combined, their effects are amplified, causing your blood pressure to lower even more. This can lead to unwanted and dangerous side effects.

How long after taking Viagra can you drink alcohol?

The effects of Viagra can last up to five hours, so it's important to limit your alcohol intake during this timeframe.

Both Viagra and alcohol relax and open up the blood vessels, which causes a drop in blood pressure. When taken together, these effects are increased, leading to a more significant decrease in blood pressure than if you had taken either Viagra or alcohol by themselves. While an occasional drink is unlikely to cause problems, it's best to be cautious.

Can women take Viagra?

The use of Viagra in women is an area of limited research. While some short-term studies have shown positive results, the effects of Viagra on women are not yet well understood.

The FDA has not approved Viagra for use by women. Without this approval, potential risks and long-term effects remain unclear. However, this does not mean Viagra cannot help some women. In certain cases, doctors may prescribe it off-label to treat sexual dysfunction.

How often can you take Viagra?

When taking Viagra, it's important to follow your doctor's instructions carefully. The recommended starting dose is 50 mg once per day, taken about one hour before sexual activity. While Viagra is generally safe when used as directed, taking it more than once a day increases your risk of side effects.

Common side effects of taking too much Viagra include headaches, upset stomach, dizziness, feeling faint, and prolonged, painful erections. To avoid unwanted side effects, do not exceed the dosage prescribed by your doctor.

What if Viagra doesn’t work?

If Viagra isn't working for you, there are still options. First, talk to your doctor about adjusting your dosage or trying another ED medication altogether. Sometimes, a different dose or drug may be more effective.

It's also important to avoid some common mistakes when taking Viagra to give it the best chance of working:

• Avoid eating a large or high-fat meal before taking Viagra. This can delay its effects.

• Limit alcohol intake. Drinking alcohol can worsen ED, so consider cutting back or eliminating alcohol to see if it helps Viagra work better.

• Be patient. Viagra takes 30 to 60 minutes to absorb into the bloodstream before it starts working.

• Make sure you're sexually aroused. Viagra facilitates an erection but doesn't cause one on its own. You still need to be stimulated for it to work.

What does a Viagra pill look like?

The appearance of a Viagra tablet depends on whether it is brand-name or generic.

• Brand-name Viagra is a blue, diamond-shaped tablet.

• Generic Viagra is a round, white tablet.
