Why is Levitra prescribed?
Levitra helps men with erectile dysfunction to achieve and sustain an erection. It is one of several drugs that may be prescribed to treat erectile dysfunction.
How long does Levitra last?
Levitra can be effective for 4-6 hours
How long does Levitra take to work?
Levitra should take effect within 60 minutes.
What does Levitra do to the body?
Levitra blocks an enzyme called PDE5. This allows muscles in the walls of blood vessels to relax, increasing blood flow that’s required to achieve and sustain an erection.
Is it safe to take Levitra with alcohol?
Drinking alcohol can actually contribute to erectile dysfunction, and may make Levitra less effective. Because both alcohol and Levitra can lower blood pressure, mixing the two increases the likelihood of side effects including dizziness and fainting.
How many times a day can I take Levitra?
Levitra should not be taken more than once daily.
Will Levitra affect my blood pressure?
Levitra can lower your blood pressure. Men who currently have low or high blood pressure should consult their doctor before taking Levitra. If you use nitrate drugs to treat chest pain, taking Levitra can cause a dangerous drop in blood pressure.

Yes, Levitra is only available with a prescription.
