Glytrin Sublingual Spray
Glytrin 400mcg Sublingual Spray is used to treat angina at the onset of an attack and can also be used to prevent angina which can be brought on from physical effort, emotional stress, and exposure to cold, etc.
Glytrin 400mcg Sublingual Spray contains the active ingredient glyceryl trinitrate, a nitrate that relaxes the muscle walls of the blood vessels and reduces the workload of the heart.
- Glytrin is not recommended for children.
- Always use Glytrin exactly as explained in this leaflet. You should check with your doctor or pharmacist if you are not sure. Learn how to use Glytrin before the onset of an angina attack, as you 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.
- Keep a spare handy at all times as it can be difficult to tell how many doses are left in the canister.
- Do not use Glytrin if you are near a naked fl ame, e.g. a cigarette.
- 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 fine mist of liquid.
- Practice aiming the spray onto a tissue or similar item so that you will be able to aim it correctly under the tongue when you need to use it. If you do not need to use Glytrin very often, remember to check the spray regularly to see that it still works properly.
- Sit down.
- Hold the canister upright and near your mouth.
- Hold your breath.
- Aim the spray under your tongue.
- Press down the button firmly, once only.
- Close your mouth immediately.
- Do not inhale the spray.
The usual dose is one or two sprays. No more than three doses are recommended at any one time. After using Glytrin, rest for a while. When you stand up, rise slowly, as you may feel faint.
