SMHeartCard is easy to fill. Put the SMHeartCard flat on a table. Remove the caps. Load four 81mg ASA pills into the ASA wells. Load three fresh Nitroglycerin 0.3 mg pills into the NTG wells. Snap the caps back into place. Done.

The easiest way to refill your Nitroglycerin pills is the refill order on the SMHeartCard home page. However, Nitroglycerin is a schedule 2 drug and you can request your Canadian pharmacist to supply Nitroglycerin  (NitroStat) 0.3 mg tablets to you. ASA 81mg is sold everywhere. To help your pharmacist, you may wish to download and print off this form.
