Levitra is an orange, round film-coated tablet that comes in the following dosages: 2.5 mg., 5 mg., 10 mg., 20 mg. This medicine is most commonly used to help men achieve an erection and maintaining it for a period of time long enough to have sex. The most common side effects include headache, upset stomach, back pain, stuffy nose, warmth and redness in your neck, chest and face. More serious side effects are allergic reaction (trouble breathing, swelling the face, lips, tongue or throat, hives), dizziness and nausea, pain and numbness in the chest, tingling in the jaw, arms and neck, painful erection for more than 4 hours, vision changes, shortness of breath and profuse sweating.
If you think you have taken too much of Levitra and experience symptoms such as back pain, vision problems or muscle pain, you need to seek immediate medical help. It's not recommended to take Levitra with grapefruit juice, as well as alcohol, since these drinks may interact with the medication. Discuss the issue of drinking alcohol and using grapefruit products with your doctor before taking Levitra. Do not start using other drugs from impotence unless told so by the doctor who knows your medical history.
