Levitra: Uses, risks and how to buy it safely

What Is Levitra?

Levitra is a drug designed to treat erectile dysfunction. Its primary ingredient is vardenafil. Vardenafil has a 15% bioavailability, 95% protein binding, hepatic metabolisation, and a 4.5 hour elimination half-life. Vardenafil’s molecular formula is C23H32N6O4S and it weighs 488.6 grams per mol. Vardenafil is marketed by Bayer Pharmaceutical, GlaxoSmithKline and Schering-Plough. Levitra comes in circular orange tablets stamped with the dosage size, either 2.5mg, 5mg, 10mg, or 20mg. The basic starting dose is 10mg. One tablet should be taken 1.5 hours prior to sexual activity. Never take more than one tablet per day. Vardenafil is similar to other PDE5 inhibitors such as sildenafil citrate and tadalafil. The main difference between vardenafil and sildenafil citrate is the position of the nitrogen atom and the ethyl group that replaces a piperazine ring. Tadalafil shares little with vardenafil in terms of its structure but has a similar effect. Vardenafil has a very short duration, only slightly longer than sildenafil citrate. Vardenafil may be useful for treating premature ejaculation, but this is poorly studied. Vardenafil is sometimes marketed as Staxyn, Levitra, Levitra Soft, or Vivanza.

Side Effects

Levitra is associated with many potent side effects. Nausea is a commonly reported reaction, along with abdominal pain, back pain, photosensitivity, abnormal vision, eye pain, facial edema, hypotension, palpitations, tachycardia, arthralgia, myalgia, rash, and itch. Vardenafil is known to cause fatal heart attacks in extremely rare circumstances. It can also cause priapism, which can escalate to permanent impotence if untreated. If you experience priapism, call a doctor immediately. Vardenafil can occasionally cause deafness as well. The FDA mandated a warning label associated with this last condition in 2007. Vardenafil should never be taken by people using nitrate medications. Nitrate medications and vardenafil can cause immediate lethal hypotension, or extremely low blood pressure. Vardenafil should not be taken in conjunction with drugs that increase the QT interval, such as amiodarone.

Vardenafil can also cause headaches, flushing, hot skin, runny nose, stuffy nose, stomach pain, heartburn, or dizziness. Vardenafil is known to occasionally cause ringing in the ears, chest pain, heavy heart, pain spreading in the arms or shoulders, sweating, ill feeling, swollen hands, swollen ankles, swollen feet, swollen elbows, shortness of breath, fainting, or seizures. If you experience one of these issues, call a doctor immediately as many of them can be lethal if untreated.

Purchasing Options

Vardenafil requires a prescription to purchase. Any stores offering vardenafil without a prescription are offshore. Only buy from reputable merchants. Levitra costs approximately 150 pennies per tablet, with discounts for larger amounts. Remember to thoroughly investigate before buying from a website. Over 60% of websites selling Levitra have also generic tablets. You can also buy from a brick and mortar physical store in Sydney such as Priceline Pharmacy. Just remember, if a merchant’s deal seems too good to be true, it probably is too good to be true.
