Sublingual (Under the Tongue) Pills
These can be used at the first sign of an attack of angina, or prior to exercising or activities that may bring on an attack of angina.
A patch applied to the skin can help to prevent angina attacks. It's worn for about 12 hours and removed for 12, depending on your Dr.'s orders.
As an angina attack begins, you use the spray on or under the tongue - using no more than 3 doses in 15 minutes. Sprays can be used in advance of exercising or activities that may bring on an attack of angina.
The amounts used will depend on your Dr.'s prescribed amount. It's put on in 'inches'. You apply it in a thin even layer and like the patches, it's only used for a prescribed amount of time during the day.
Sustained-Release Capsules or Tablets
Usually you would use the smallest effective amount taken 2-3 times a day at 8-12 hours, or as prescribed.
