Levitra Patient Information
WHAT IS LEVITRA USED FOR?
LEVITRA is used to treat erectile dysfunction sometimes known as impotence in men. Erectile dysfunction is the inability to obtain and or maintain a hard erect penis for sexual activity.
LEVITRA tablets contain the active ingredient vardenafil (present as vardenafil hydrochloride trihydrate) which belongs to a group of medicines called phosphodiesterase type 5 inhibitors. These work by relaxing the blood vessels in the penis when you are sexually aroused. This allows blood to flow into the penis, allowing you to get an erection in the natural way.
LEVITRA will only work if you are sexually excited. It will not increase your sex drive.
LEVITRA is not approved for use in women.
LEVITRA tablets are not addictive.
BEFORE YOU TAKE LEVITRA
When you must not take it:
Because sexual activity may place a strain on your heart, your doctor will need to check whether you are fit enough to use LEVITRA.

You should not use LEVITRA together with other treatments for erectile dysfunction.
Do not take LEVITRA if you have an allergy to vardenafil or other phosphodiesterase type 5 inhibitors, or any of the ingredients in LEVITRA tablets listed at the end of this leaflet. Some of the symptoms of an allergic reaction may include skin rash, itching, or difficulty breathing.

Examples of alpha-blockers areterazosin, tamsulosin and prazosin.

HOW TO TAKE LEVITRA
Your doctor or pharmacist will tell you how much and how often you should take LEVITRA. Follow the directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.
The dose ranges from 5 mg to 20 mg. Your doctor will determine the correct dose for you depending on your condition and response.
Do not take more than one dose of LEVITRA a day.
Take your dose of LEVITRA 25 to 60 minutes before you wish to have sex. Swallow the tablet whole with a glass of water.
Sexual stimulation is required for a natural response to treatment with LEVITRA.
LEVITRA can be taken with or without food.
The medicine may be taken anywhere between 15 minutes to up to 5 hours before sexual activity. The amount of time LEVITRA takes to start working varies from person to person, but it normally takes between 25 to 60 minutes.
If LEVITRA does not help you get an erection, or if your erection does not last long enough to complete sexual intercourse, tell your doctor. In these cases, your doctor may need to adjust your dose.
Things you must not do:
If you get an angina attack while taking LEVITRA, do not take nitrate medicines to relieve the pain. Tell your doctor immediately. Make sure that your doctor knows you are taking LEVITRA.
Do not take more than one dose of LEVITRA a day. If LEVITRA does not help you get an erection, or if your erection does not last long enough to complete sexual intercourse, tell your doctor.
Do not give your LEVITRA tablets to anyone else, even if they have the same condition as you.
What to be careful of:
Drinking alcohol can temporarily impair the ability to get an erection. To reduce impairment do not drink large amounts of alcohol before sexual activity.
Be careful driving or operating machinery until you know how LEVITRA affects you. LEVITRA tablets may cause dizziness or faintness in some patients. The ability to drive and/or operate machinery may be impaired. If you drink alcohol, dizziness or faintness may be worse.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking LEVITRA. LEVITRA helps most men with erectile dysfunction, but it may have unwanted side effects. Sometimes they are serious, most of the time they are not. You may need to stop taking the tablets or have medical treatment if you get some of the serious side effects.
Tell your doctor if you notice any of the following and they worry you:
headache, flushing, dyspepsia (heartburn), nausea, dizziness or light-headedness, a stuffy or runny nose, sensitivity of the eye to sunlight, high or low blood pressure, stiffness in muscles, pain in the joints, rash, stomach or abdominal pain.
These are the more common side effects of LEVITRA. They are usually mild and short-lived. Very rarely, your erection may persist for longer than usual. If your erection continues for longer than four hours, or if you have a painful erection, you should seek medical attention.
Tell your doctor immediately, or go to the accident and emergency department at your nearest hospital if you notice any of the following: severe chest pain, angina, irregular heart beats, loss of consciousness.
These are serious side effects. You may need urgent medical attention or hospitalization.
Other side effects not listed above may also occur in some patients. Tell your doctor if you notice anything else that is making you feel unwell.
Do not be alarmed by this list of possible side effects. You may not experience any of them.
