As with all drugs Levitra has risky side effects that you need to be well informed of before you start taking this medication. If you experience a loss of vision you need to contact emergency medical care immediately. Other side effects include shortness or loss of breath, swelling in your feet, legs or hands, headache, nausea, tingling or numbness in your face, arms, chest or neck. You might also experience being light headed, ringing in the ears or sweating. If your erection last for longer than 4 hours or becomes painfully you need to cease all sexual activity and call your physician right away.

There are also a few less serious side effects that you should be aware of. These less serious side effects of the Levitra drug include back pain, stuffy or runny nose, redness or a warmth in your neck, face, chest or shoulders and stomach upset. If you experience any of these less serious side effects from taking Levitra you should slow down in your sexual activity but you do not need to cease activity.
