Clinical trials and medical reports say that most commonly met complaints of patients taking Levitra are headaches, flushing, stuffy or runny nose, an upset stomach, dizziness. Rarely cases of priapism were also reported. Priapism refers to erections that won't go away and may cause severe damage to the penis if it isn't urgently treated. It may even lead to permanent inability of having erections. Also uncommon were vision changes such as confusing colors blue and green or seeing blue tinge to objects.

Contraindications in taking Levitra are very similar to those in taking any other PDE5 Inhibitor. Men taking nitrates commonly used to treat angina should avoid Levitra. Nitrates can also be found in isosorbide dinitrate or isosorbide nitrate and in 'poppers'-recreational drugs. The combination of nitrates with vardenafil is contraindicated because vardenafil potentiates the hypotensive effects of nitric substances.

Men with cardiovascular disease are also not advised to use PDE5 Inhibitors, physicians should pay attention at prescribing vardenafil to incompletely diagnosed patients.
Until further research, patients suffering from unstable angina, orthostatic hypotension, hypertension, myocardial infarction, stroke, cardiac ischemia, life threatening arrhythmia, hepatic impairment, renal disease requiring dyalisis and retinal disorders meet the same contraindications of taking Levitra.
Physicians also recommend avoiding concomitant use of Levitra and indinavir or ritonavir because they are powerful inhibitors of CYP3A4. if they are however used simultaneously the dose of vardenafil should be lowered.

Patients taking alpha-blockers are advised not to use vardenafil. Alpha-blockers may be prescribed for prostate dysfunction or high blood pressure. In the same situation of avoiding Levitra are all men allergic to it or its ingredients.
