used for the prevention of angina, which can be brought on from
physical effort, emotional stress, and exposure to cold, etc.

ingredients of this medicine (listed in section 6).

may need to use it in a hurry, or in the dark. Familiarise yourself with
the spray button, which has a finger rest to help you direct the spray.

many doses are left in the canister.

6. Before using Glytrin for the first time, check that the spray
is working by pressing the pump button a few times until it
produces a fi ne mist of liquid. Practice aiming the spray onto a
