A blood pressure medication mix-up has led to a Canada-wide recall.


Health Canada has recalled MAR-Amlodipine 5 mg tablets, which treat high blood pressure and chest pain, as some bottles may contain the wrong drug.


Marcan Pharmaceuticals Inc. says certain bottles labelled as MAR-Amlodipine may actually contain midodrine 2.5 mg tablets, a medication used to treat low blood pressure.

Taking midodrine instead of amlodipine could lead to serious health risks, including dangerously high blood pressure, dizziness, fainting, slow heartbeats, and potential organ damage, according to the agency.

Additionally, children may face a higher risk of harm if they take the incorrect medication.

What to look for
To discern the difference in medications, the correct MAR-Amlodipine tablets have eight sides, are white to off-white in colour, and have the numbers “210” and “5” printed on one side (pictured above, on the left).

Meanwhile, Midodrine 2.5 mg tablets (pictured above, on the right), which were mistakenly put in the bottles, are round in shape and are marked with “M2.”


The affected product is MAR-Amlodipine 5 mg, DIN 02371715, from lots 2472021 and 2472021A, with an expiry date of July 2027, according to the public advisory.

Consumers with questions can contact Marcan Pharmaceuticals Inc. directly, and health-care professionals are being asked to carefully check bottles before dispensing and report any issues.

What to do if you have or have taken wrong meds
If your bottle of MAR-Amlodipine contains the wrong tablets, do not take them and return them to your pharmacy.

If you accidentally took the wrong medication, see a health-care professional or call 911 if you feel dizzy, have unusually high blood pressure or a slow heartbeat, Health Canada advises.

If you are experiencing chest pain, a sudden headache, impaired speech or are unable to move or feel part of your body, seek immediate medical attention.
