Benzydamine is an anti-inflammatory and painkilling medicine. It reduces pain and discomfort associated with sore throat or mouth conditions such as ulcers and sore throat. It is available as lozenges to suck, a mouthwash which you can gargle with, or as a spray which can be directed towards the sore areas of your mouth.
Benzydamine mouthwash, lozenges and spray are available on a prescription from a doctor or dentist. You can also buy them at a pharmacy, without a prescription.
Before using benzydamine
Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start using benzydamine it is important that your doctor, dentist or pharmacist knows:
- If you are pregnant or breastfeeding. This is because, while you are expecting or feeding a baby, you should only take medicines on the recommendation of a doctor.
- If you have ever had an allergic reaction to a medicine.
- If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.
How to use benzydamine
- Before you start the treatment, read the manufacturer's printed information leaflet from the pack. It will give you more information about benzydamine and will provide you with a full list of any side-effects which you may experience from using it.
- If you are using benzydamine oral rinse (mouthwash), use 15 ml as a mouthwash every 1½-3 hours. The cap of the bottle can be used as a measure. After you have gargled with the liquid for about 20-30 seconds, spit it out - try not to swallow benzydamine. If you find the mouthwash causes some stinging, you can dilute the liquid with an equal amount of water before you use it. This oral rinse is not suitable for children under 13 years of age to use.
- If you are using benzydamine spray, use 4-8 sprays on to the sore area every 1½-3 hours. This is the dose for adults. If you are giving benzydamine to your child, check the label carefully to make sure you are using the correct number of sprays for the age of your child.
- If you are using benzydamine lozenges, the dose for adults and for children over 6 years is one lozenge three times daily. Allow the lozenge to dissolve slowly in your mouth, do not swallow whole and do not chew. Do not use the lozenges for more than seven days.
How to use benzydamine spray
- Hold the bottle upright.
- Lift the nozzle of the spray away from the container until it is horizontal.
- If it is the first time you have used the spray, point the nozzle away from you and press down on the green plunger on the top of the container until you see a fine mist. The spray is now ready to use.
- Aim the spray at the sore area of your mouth or throat and press down on the green plunger to release one spray. Repeat this step to give the correct number of sprays.
- When you have finished using the spray, push the nozzle of the spray back down against the container to store it safely until your next dose is due.
Getting the most from your treatment
- You should expect the soreness to have eased within seven days of using benzydamine. If there is no improvement after this time, you should arrange to see your doctor or dentist for further advice. Do not continue to use benzydamine for longer than seven days unless it is on the advice of a doctor or dentist.
- If you are using the spray, be careful not to get it into your eyes. If this does happen by accident, rinse it out with warm water.
