If you take the drug MAR-Amlodipine you are urged to check the bottle.

Health Canada has issued notice of a recall for the 5-milligram tablets. The correct tablets are white to off-white and eight-sided. If your bottle contains any round tablets, return the bottle to your pharmacy for a replacement. Do not take the round tablets.

Health Canada says contact your health care professional or call 911 if you are dizzy, have unusually high blood pressure or slow heartbeats. Seek immediate medical attention if you have chest pain, a sudden headache, an inability to move or feel a part of your body, or impaired speech.

The round tablets are 2.5 milligram Midodrine, marked with ‘M2’ on one side and have a line across the middle on the other side. They are used to treat low blood pressure.
