How Is Levitra Normally Prescribed?

Levitra is a prescription drug that treats erectile dysfunction or impotence. A beginning dose for most patients is 10 mg, taken about 1 hour before starting sexual activity. After that, Levitra should be taken one time at most per day. You can take Levitra with or without food.

Standard Levitra Dose Adjustments

Levitra doses can be raised to 20 mg or lowered to 5 mg, depending on your tolerance and reactions. Some patients, including patients over 65 years of age, may start with the 5 mg dosage.

  • Ritonavir
  • Indinavir
  • Saquinavir
  • Atazanavir

Common Levitra Side Effects

Levitra can cause side effects in some patients. Side effects from taking Levitra are rare, but they can cause significant problems. Therefore, you should pay attention to your body’s reactions whenever you take Levitra. If you notice any severe side effects, stop taking Levitra and contact your doctor immediately.

Cardiovascular Effects Of Levitra

Levitra impacts your body’s cardiovascular system. This medicine improves your blood flow and circulation to make it easier to have an erection. However, this effect also affects the rest of your circulatory system. As a result, patients can experience blood pressure drops and other cardiovascular side effects. Only take Levitra if you’re healthy enough for sex or other vigorous forms of exercise. If you have a heart or lung condition, taking Levitra might put you at risk.

Levitra may not be safe for you to take if you’ve experienced any of the following:

  • Unstable angina
  • High or low blood pressure
  • Left ventricular outflow obstructions such as aortic stenosis or idiopathic hypertrophic subaortic stenosis
  • Impaired autonomic blood pressure control

Prolonged Erections While Taking Levitra

In rare cases, men who take Levitra experience long-lasting, painful erections. These conditions include prolonged erections, which last for four hours or more, or priapism when an erection lasts for six hours or more. You should immediately seek medical treatment if you have an erection lasting for four hours or longer. This condition can permanently damage your penis and cause lifelong impotence.

Check with your doctor if Levitra is safe for you if you have any of the following concerns:

  • Cavernosal fibrosis
  • Peyronie’s disease
  • Angulated penis
  • Other anatomical conditions of the penis
  • Sickle cell anemia
  • Multiple myeloma
  • Leukemia

Levitra And Vision Loss

Levitra has been known to cause sudden vision loss in a few patients. This loss can signify non-arteritic anterior ischemic optic neuropathy (NAION), a rare condition that can cause vision loss. Some patients may experience permanent vision loss. You’re more likely to have a NAION event while taking Levitra if you’re already experienced NAION.

Levitra And Hearing Loss

Some patients also experience sudden hearing loss while using Levitra. Researchers don’t fully understand this side effect or how to prevent it. Other patients have reported ringing in the ears, tinnitus, or dizziness. Contact your medical team if you notice any of these symptoms while using Levitra.

Low Blood Pressure And Levitra

Levitra can cause your blood pressure to drop because it increases blood flow. This side effect can cause problems for patients who already have low blood pressure or are on blood pressure medication. Stop taking Levitra and contact your doctor if you feel dizzy or lightheaded while using this medication.

Basic Information For Levitra Patients

What Is Levitra?

Levitra is a prescription drug that treats erectile dysfunction. Many men find it easier to get an erection from sexual stimulation when taking Levitra. However, Levitra won’t cause you to have an erection without being sexually aroused. Therefore, women and children should not take Levitra.

What Are The Most Important Things To Know About Taking Levitra?

Levitra can make your blood pressure drop to a dangerously low level. As a result, you may become dizzy, pass out, or have a stroke or heart attack. This side effect is a more significant risk if you take Levitra and certain other medicines simultaneously. For example, never take Levitra and nitrates together. Nitrates are drugs to treat angina or chest pain. You should also not take Levitra with the street drug known as “poppers” since these drugs also contain nitrates.

Tell Your Entire Medical Team That You Take Levitra

Think of healthcare as a team sport. You should tell all your medical providers that you take Levitra. This includes doctors, pharmacists, dentists, emergency providers, nurses, EMTs, physical therapists, and anyone who treats you. 

Levitra is safe when used appropriately, but it can also cause you to have serious side effects when combined with other medicines. Your medical providers can give you the best care when they know your entire medical history. You’ll also need to tell emergency providers the last time you took a dose of Levitra if you experience heart problems or another emergency.

Know When To Get Help

If you’re recovering from heart disease, sexual activity can put a dangerous amount of strain on your heart. Get help immediately if you have chest pain, nausea, or dizziness while having sex.

Levitra isn’t male birth control and doesn’t protect against pregnancy or sexually transmitted diseases. You and your partner should still use safer sexual practices to protect yourselves.

Who Should Not Take Levitra

Don’t use Levitra if you:

  • Use nitrate medications
  • Take street drugs known as “poppers.”
