What Enablex is used for

Enablex is used to decrease the urgency and the frequency of urination.

Enablex works by relaxing the bladder smooth muscle and helps to decrease muscle spasm. This delays the initial desire and the urge to urinate.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

This medicine is available only with a doctor’s prescription. It is not addictive.

Enablex is not recommended for use in children because there have been no studies of its effects in this age group.

How to take Enablex

Follow all directions given to you by your doctor and pharmacist carefully. These instructions may differ from the information contained in this leaflet.

If you do not understand the instructions on the label, ask your doctor or pharmacist for help.

How much to take

The usual starting dose is one 7.5 mg tablet once a day.

If necessary, your doctor may increase your dose to one 15 mg tablet once a day, as early as two weeks after starting therapy.

If you have a problem with your liver or are taking certain medicines, your doctor may limit your dose to one 7.5 mg tablet once a day.

How to take it

Swallow the tablet whole with a glass of water. Do not chew, crush or divide the tablet.

You can take the tablet with or without food.

When to take it

Take Enablex at about the same time each day. Taking your tablet at the same time each day will have the best effect. It will also help you remember when to take it.

If you forget to take it

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.

Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.

If you are not sure what to do, ask your doctor or pharmacist.

If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

How long to take it

Continue taking this medicine for as long as your doctor tells you to. Enablex helps control your condition, but does not cure it. Therefore, you must take this medicine every day.

If you take too much (overdose)

Immediately telephone your doctor or pharmacist or the Poisons Information Centre (telephone 13 11 26), or go to accident and emergency at your nearest hospital, if you think that you or anyone else may have taken too much Enablex. Do this even if there are no signs of discomfort or poisoning.

Keep the telephone numbers for these places handy.

Tell any other doctors, dentists, and pharmacists who are treating you that you are taking Enablex.

Things you must not do

Do not give this medicine to anyone else, even if their condition seems similar to yours.

Do not take it to treat any other complaints unless your doctor tells you to.
