Levitra Side Effects - for the Professional

Levitra

Levitra was administered to over 4430 men (mean age 56, range 18-89 years; 81% White, 6% Black, 2% Asian, 2% Hispanic and 9% Other) during controlled and uncontrolled clinical trials worldwide. Over 2200 patients were treated for 6 months or longer, and 880 patients were treated for at least 1 year.

In placebo-controlled clinical trials, the discontinuation rate due to adverse events was 3.4% for Levitra compared to 1.1% for placebo.

When Levitra was taken as recommended in placebo-controlled clinical trials, the following adverse events were reported.

Table 5: Adverse Events Reported By ≥2% of Patients Treated with Levitra and More Frequent on Drug than Placebo in Fixed and Flexible* Dose Randomized, Controlled Trials of 5 mg, 10 mg, or 20 mg Vardenafil
Adverse Event Percentage of Patients Reporting Event
Placebo
N = 1199
Levitra
N = 2203
*
Flexible dose studies started all patients at Levitra 10 mg and allowed decrease in dose to 5 mg or increase in dose to 20 mg based on side effects and efficacy.
All the events listed in the above table were deemed to be adverse drug reactions with the exception of accidental injury.
Headache 4% 15%
Flushing 1% 11%
Rhinitis 3% 9%
Dyspepsia 1% 4%
Accidental Injury 2% 3%
Sinusitis 1% 3%
Flu Syndrome 2% 3%
Dizziness 1% 2%
Increased Creatine Kinase 1% 2%
Nausea 1% 2%

Back pain was reported in 2.0% of patients treated with Levitra and 1.7% of patients on placebo.

Placebo-controlled trials suggested a dose effect in the incidence of some adverse events (headache, flushing, dyspepsia, nausea, rhinitis) over the 5 mg, 10 mg, and 20 mg doses of Levitra. The following section identifies additional, less frequent events (<2%) reported during the clinical development of Levitra. Excluded from this list are those events that are infrequent and minor, those events that may be commonly observed in the absence of drug therapy, and those events that are not reasonably associated with the drug.

   BODY AS A WHOLE: anaphylactic reaction (including laryngeal edema),
   asthenia, face edema, pain

   AUDITORY: sudden decrease or loss of hearing, tinnitus

   CARDIOVASCULAR: angina pectoris, chest pain, hypertension,
   hypotension, myocardial ischemia, myocardial infarction, palpitation,
   postural hypotension, syncope, tachycardia

   DIGESTIVE: abdominal pain, abnormal liver function tests, diarrhea, dry
   mouth, dysphagia, esophagitis, gastritis, gastroesophageal reflux, GGTP
   increased, vomiting

   MUSCULOSKELETAL: arthralgia, back pain, myalgia, neck pain

   NERVOUS: hypertonia, hypesthesia, insomnia, paresthesia, somnolence,
   vertigo

   RESPIRATORY: dyspnea, epistaxis, pharyngitis

   SKIN AND APPENDAGES: photosensitivity reaction, pruritus, rash,
   sweating

   OPHTHALMOLOGIC: abnormal vision, blurred vision, chromatopsia,
   changes in color vision, conjunctivitis (increased redness of the eye), dim

Side Effects by Body System

Cardiovascular

Cardiovascular side effects have included flushing (vasodilation) in 11% and dizziness in 2% of patients. Consistent with its known effects on the nitric oxide/cGMP pathway, use of sildenafil has been shown to potentiate the hypotensive effects of nitrates, and its administration to patients who are concurrently taking organic nitrates is considered contraindicated. The following cardiovascular side effects have been associated with the use of sildenafil in less than 2% of patients: angina pectoris, chest pain, hypertension, hypotension, myocardial ischemia, palpitation, postural hypotension, syncope, and tachycardia. Congenital or Acquired QT Prolongation: In a study on the effect of vardenafil on QT interval in 59 healthy males, therapeutic (10 mg) and supratherapeutic (80 mg) doses of vardenafil and the active control moxifloxacin (400 mg) produced similar increases in QTc interval. These observations should be considered in clinical decisions when prescribing vardenafil to patients with known history of QT prolongation or patients who are taking medications known to prolong the QT interval.

Dermatologic

Dermatologic side effects have been reported in less than 2% of patients and include photosensitivity reaction, pruritus, rash, and sweating,

Gastrointestinal

Gastrointestinal side effects have included dyspepsia (4%) and nausea (2%). Less common gastrointestinal complaints have included abdominal pain, diarrhea, dry mouth, dysphagia, esophagitis, gastritis, gastroesophageal reflux and vomiting (less than 2% of patients).

Hepatic

Hepatic side effects have included increased creatine kinase (2%). Other hepatic side effects (less than 2%) have included other abnormal liver function tests.

Genitourinary

Genitourinary side effects have been reported in less than 2% of patients and included abnormal ejaculation and priapism (including prolonged or painful erections). In the event of an erection that persists longer than 4 hours, the patient should seek immediate medical assistance. If priapism is not treated immediately, penile tissue damage and permanent loss of potency could result.

Musculoskeletal

Musculoskeletal side effects have been reported in less than 2% of patients. They include arthralgia, back pain, myalgia, and neck pain.

Nervous system

Nervous system side effects have included headache (16%) and dizziness (2%). Other nervous system side effects reported in less than 2% of patients have included hypertonia, hypesthesia, insomnia, paresthesia, somnolence, and vertigo. Seizure and seizure recurrence have been reported postmarketing in temporal association with vardenafil. Transient global amnesia has also been reported postmarketing in temporal association with vardenafil.

Ocular

Non-arteritic anterior ischemic optic neuropathy (NAION), a cause of decreased vision including permanent loss of vision, has been reported rarely postmarketing in temporal association with the use of phosphodiesterase type 5 (PDE5) inhibitors, including vardenafil.

Ocular side effects have been reported in less than 2% of patients and have included abnormal vision, blurred vision, chromatopsia, changes in color vision, conjunctivitis, dim vision, eye pain, glaucoma, photophobia, and watery eyes.

Respiratory

Respiratory system side effects have included rhinitis (9%) and sinusitis (3%). Other respiratory system side effects that occurred in more than 2% of patients have included dyspnea, epistaxis, and pharyngitis.

Other

Other side effects have included tinnitus. Cases of sudden decrease or loss of hearing reported postmarketing in temporal association with the use of PDE5 inhibitors, including vardenafil. In some cases, medical conditions and other factors were reported that may have also played a role in the otologic adverse events. In many cases, medical follow-up information was limited. It is not possible to determine whether these reported events are related directly to the use of vardenafil, to the patient's underlying risk factors for hearing loss, a combination of these factors, or to other factors.

General

General side effects have included accidental injury (3%) and flu syndrome (3%). Other side effects occurring in less than 2% of patients include: anaphylactic reaction (including laryngeal edema), asthenia, face edema and pain.
