It is prescribed to help males achieve stronger erection during sexual activity. Levitra works by dilating blood vessels in the penis and thereby causing more blood to rush into it leading to a stronger erection.
Levitra must be taken at least one hour prior to sexual activity with or without food. The drug should not be taken more than once a day.
Take only when required (prior to sexual activity). Do not take a double dose ever.
Store it at room temperature.
Some of the typical symptoms of an overdose include chest pain, back pain, dizziness and irregular heartbeat and abnormal vision. Seek medical attention immediately if you suspect an overdose.
Do not take Levitra if you are taking medications containing nitrates, alpha–blockers. Do not consume alcohol along with the drug. Do not drive or handle heavy machinery until you know how to react to the drug.
