Levitra is a prescription medication that was approved by the FDA in 2003 to treat erectile dysfunction (ED) in men 18 years and older. It contains vardenafil, which increases blood flow to the penis. This helps men achieve and maintain an erection during sexual arousal.

Clinical trials show Levitra can be highly effective for erectile dysfunction. In one study, 85% of men reported improved erections after taking Levitra compared to 45% who took a placebo.

It's important to note that Levitra, like other ED medications, only works when you are sexually stimulated. It will not produce an erection on its own without arousal. It simply improves blood flow so you can get and maintain an erection.

If you have been struggling with ED, talk to your doctor. Let them know about your symptoms and discuss whether a prescription medication like Levitra might help. When it comes time to fill your prescription, using an online Canadian pharmacy like My Drug Center can help you save up to 90% on medication costs.

When you become aroused, your nerves send signals that release nitric oxide, a chemical that increases blood flow to the penis. The surge of blood flow leads to an erection.

However, some chemicals in your body work to reverse this process, like phosphodiesterase type 5 (PDE5). This is perfectly normal and helps regulate erectile function.

For some men, though, the effects of PDE5 happen too quickly, making it difficult to maintain an erection long enough for sex. That's where medications like Levitra come in.

Levitra contains an active ingredient called vardenafil, which belongs to a class of drugs known as PDE5 inhibitors. These work by blocking the effects of PDE5, allowing increased blood flow to the penis to continue so you can sustain an erection.

It's important to keep in mind that Levitra does not directly give you an erection. You still need to become aroused for Levitra to be effective. Levitra only works to maintain the erection by preventing PDE5 from reversing the arousal process too quickly.

Levitra comes in tablet form and is taken orally. It is available in four strengths: 2.5 mg, 5 mg, 10 mg, and 20 mg.

For most patients, the recommended starting dose of Levitra is 10 mg, taken orally about an hour before sexual activity. Your doctor may then adjust your dose based on how well it works and any side effects you experience. The dose can be increased up to the maximum of 20 mg or decreased to 5 mg. Levitra should not be taken more than once a day.

Levitra is generally well-tolerated by most men. However, like any medication, Levitra can cause side effects in some people. It's important to be aware of potential side effects and let your doctor know if any concerning symptoms arise.

Mild Levitra side effects include:

• Flushing (sudden warmth, redness, or tingly feeling)
• Stuffy nose
• Sinus pain
• Headache
• Dizziness
• Upset stomach
• Back pain

Levitra can also cause serious side effects. Seek immediate medical attention if you experience any of the following:

• Ringing in your ears
• Irregular heartbeat
• Swelling in your hands, ankles, or feet
• Shortness of breath
• Feeling light-headed
• Seizures

How long does Levitra last?

Levitra lasts for about four hours. During this time, you can achieve an erection when sexual stimulation occurs.

How long does it take for Levitra to work?

After taking Levitra, it can take 60 minutes for the medication to start working properly. This is because Levitra needs to be absorbed into your bloodstream before it can take full effect.

Can I drink alcohol while taking Levitra?

Both Levitra and alcohol are vasodilators, meaning they relax and widen your blood vessels, which can lower your blood pressure. When taken together, their blood pressure-lowering effects are enhanced, potentially causing your blood pressure to drop more significantly compared to taking either Levitra or alcohol alone.

If drinking is unavoidable, limit your intake to one or two drinks. Keep in mind that Levitra's effects can last up to four hours, and alcohol should be used cautiously in this timeframe.
