How to use benzydamine
There are different ways of using benzydamine.
How to use mouthwash
Gargle with the mouthwash or rinse it around your mouth for about 20 to 30 seconds, then spit it out.
Use the measuring cup that comes with your medicine, so you get the right dose.
Do not swallow the mouthwash.
Wait at least 1 hour and 30 minutes between doses.
How to use mouth spray
There should be a plastic tube called a spray arm at the top of the bottle. This helps a sore throat because the spray can reach the back of the throat to control the pain.
- Hold the bottle in an upright position and gently lift the spray arm so it’s sticking straight out.
- When using the spray for the first time, point the spray arm away from your face and press the plunger at the top of the bottle a few times until a fine mist comes out.
- Aim the spray arm at the sore part of your throat or mouth and press the plunger. Press the plunger the number of spray doses needed. It can go up to 4 times or 8 times for some adult doses.
- Wipe the end of the spray arm with a clean tissue when you've finished. This will stop it becoming blocked.
- Push the spray arm down, to rest against the side of the bottle.
Keep benzydamine away from your eyes.
How to take lozenges
When you have a lozenge, put it in your mouth and allow it to dissolve slowly. Do not chew or swallow it whole.
