HEALTH CANADA ADVISORY
February 4, 2014
Health Canada has issued new restrictions concerning the use of perindopril. To read the full Health Canada Advisory, visit Health Canada's web site at www.hc-sc.gc.ca.
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Angioedema: Although not common, angioedema (a serious allergic reaction that causes the area around the throat and tongue to swell) may occur with ACE inhibitors, including perindopril. If you experience swelling of the face, tongue, or glottis, stop taking perindopril at once and seek immediate medical attention. People who have had angioedema caused by other substances may be at increased risk of angioedema while taking an ACE inhibitor such as perindopril.
Diabetes: Perindopril may affect blood sugar control. People with diabetes should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. You may need to test your blood sugar more often when you first start taking this medication.
Fluid and electrolyte balance: Increases in blood levels of potassium may occur as a result of taking perindopril. This rarely causes problems, but your doctor will probably want to monitor your potassium levels regularly with blood tests.
Kidney function: Changes in kidney function have been seen in certain people. The use of diuretics (water pills) may further increase the risk of kidney problems for those already at risk for this. People with kidney disease should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver disease: People with liver disease should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Low blood pressure: Occasionally, blood pressure drops too low after perindopril is taken. This usually happens after the first or second dose or when the dose is increased. It is more likely to occur for those who take water pills, have a salt-restricted diet, are on dialysis, are suffering from diarrhea or vomiting, or have been sweating excessively and not taking in enough fluids. If low blood pressure causes you to faint or feel lightheaded, contact your doctor.
Pregnancy: Perindopril must not be taken by pregnant women. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are taking perindopril, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of the use of perindopril by children have not been established. Its use by this age group is not recommended.
What other drugs could interact with this medication?
There may be an interaction between perindopril and any of the following:
- antidiabetes medications (e.g., insulin, metformin, glyburide)
- diuretics (e.g., spironolactone, amiloride, furosemide, hydrochlorothiazide)
- medications that lower blood pressure (e.g., beta-blockers, amitriptyline, anesthetics, haloperidol, olanzapine)
- nonsteroidal anti-inflammatory medications (NSAIDs; e.g., indomethacin, naproxen)
- other blood pressure medications known as angiotensin II receptor blockers (e.g., candesartan, losartan)
- potassium supplements
- salt substitutes containing potassium
If you are taking any of these medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:
- stop taking one of the medications,
- change one of the medications to another,
- change how you are taking one or both of the medications, or
- leave everything as is.
An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.
Medications other than those listed above may interact with this medication. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.
