Self-administration: Using Sublingual Sprays

Sublingual sprays are used when immediate drug action is needed. For example, they are used to relieve the symptoms of an angina attack. The drugs are absorbed into the blood through the tongue’s rich supply of blood vessels. This is a much faster route than absorption from the digestive tract, which occurs when drugs are taken orally.

Using the spray

With an open mouth, touch the roof of your mouth with your tongue and spray on to the underside of your tongue. Avoid inhaling through your mouth at the same time as you spray the drug.
