1. WHAT PRESCAL IS AND WHAT IT’S USED FOR
Prescal contains 2.5 mg of the active ingredient isradipine. Isradipine is one of a group of drugs called
calcium channel blockers or calcium antagonists. It works by relaxing the blood vessels so the heart
does not have to pump as hard.
Prescal is used to treat high blood pressure.
2. THINGS TO CONSIDER BEFORE YOU START TO TAKE PRESCAL
Some people MUST NOT take Prescal. Talk to your doctor if:
• You think you may be allergic to isradipine, or other similar calcium channel blockers (e.g.
amlodipine, felodipine, lacidipine, nicardipine, nifedipine), or to any of the other ingredients of
Prescal. (These are listed in Section 6.)
• You have recently (within the last month) had a heart attack.
• You suffer from heart, heart valve or blood vessel disorders other than high blood pressure.
• You have unstable angina.
• You are breast feeding.
You should also ask yourself these questions before taking Prescal. If the answer to any of
these questions is YES, tell your doctor or pharmacist.
• Do you have diabetes?
• Do you have any liver or kidney problems?
• Are you pregnant or trying to become pregnant?
• Do you suffer from episodes of irregular heart beat?
• Do you have low blood pressure?
• Are you taking drugs called beta-blockers?
• Do you have an inherited intolerance to some sugars? These tablets contain a small amount of
lactose.
Are you taking other medicines?
Some medicines can interfere with your treatment or alter blood levels of those drugs you are
currently taking. Make sure your doctor knows if you are taking any of the following:
• Beta blockers (e.g. for heart problems or low blood pressure).
• Medicines to treat stomach ulcers such as cimetidine.
• Macrolide antibiotics (e.g. erythromycin, clarithromycin).
• Rifampicin used to treat e.g. tuberculosis or leprosy.
• Medicines for epilepsy (e.g. phenytoin, carbamazepine and phenobarbital).
• Anti-viral drugs (e.g. ritonavir, indinavir, nelfinavir and delavirdine).
• Oral anti-fungal drugs (e.g. ketoconazole itraconazole, voriconazole).
• Oral baclofen, a treatment for prolonged muscle spasms.
Always tell your doctor about all the medicines you are taking. This means medicines you have bought
yourself as well as medicines on prescription from your doctor.
Will there be any problems with driving or using machinery?
Prescal may makes you feel dizzy, lower your blood pressure too much (hypotension), cause vision
disorder or blurred vision. If you experience these symptoms, you should not drive or use machines.
3. HOW TO TAKE PRESCAL
The doctor will decide what dose of Prescal you should take. Always take the medicine exactly as
your doctor has told you to. The dose will be on the pharmacist’s label. Check the label carefully. It
should tell you how much to take, and how often. If you are not sure, ask your doctor or pharmacist.
Keep taking Prescal for as long as you have been told unless you have any problems. In that case,
check with your doctor.
Swallow the tablets whole with a drink of water. You can take the tablets either before or after food.
Do not take the tablets with grapefruit juice.
The usual dose for adults is:
2.5 mg twice a day.
If your blood pressure is still not controlled after three or four weeks, your doctor may decide either to
increase the dose, or to give you another medicine to take at the same time.
For the elderly, or people with liver or kidney problems, a suitable starting dose is:
1.25 mg (half a tablet) twice a day.
If necessary, the tablets should be broken in half along the scored line.
Prescal is not recommended for children.
What if you forget to take a dose?
If you forget to take a dose, take it as soon as you remember. Then go on as before. Do not take a
double dose.
What if you take too much?
If you accidentally take too much, tell your doctor at once or contact your nearest hospital casualty
department. Take your medicine with you so that people can see what you have taken.
