If you are not sure if any of the above applies to you, talk to your doctor, dentist or pharmacist before using Benzydamine Spray.
Please tell your doctor, dentist or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription.
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine. You should not use Benzydamine Spray during pregnancy unless clearly necessary and advised by your doctor.
If you need treatment the lowest dose for the shortest time possible should be used.
Do not take this product if you are in the last 3 months of pregnancy as it could harm your unborn child or cause problems at delivery. It can cause kidney and heart problems in your unborn baby. It may affect your and your baby’s tendency to bleed and cause labour to be later or longer than expected. You should not take Benzydamine Spray during the first 6 months of pregnancy unless absolutely necessary and advised by your doctor. If you need treatment during this period or while you are trying to get pregnant, the lowest dose for the shortest time possible should be used. If taken for more than a few days from 20 weeks of pregnancy onward, Benzydamine Spray can cause kidney problems in your unborn baby that may lead to low levels of amniotic fluid that surrounds the baby (oligohydramnios) or narrowing of a blood vessel (ductus arteriosus) in the heart of the baby. If you need treatment for longer than a few days, your doctor may recommend additional monitoring.

Contact your doctor, dentist or pharmacist if your symptoms worsen or they do not improve.
1. To use the spray, hold the bottle in an upright position.
2 Lift the spray-tube through 90° until it is horizontal. Do not raise the spray-tube more than shown in the diagram.
3. The first time you use the spray or after a long period of not using the spray, you need to prime it. Point the spray-tube away from your face. Press down firmly on the plunger at least 3 times until a fine spray appears from the end of the spray tube. The spray is now ready to use.
4. Aim the spray-tube at the sore part of your mouth or throat and press down on the plunger again. One press releases one spray of medicine.
5. After spraying the correct number of sprays according to dosage above, wipe the end of the spray-tube with a tissue. This helps to stop it becoming blocked.
6. Push the spray-tube back down as shown in the diagram. This stops any sprays being accidentally released.
7. Do not push anything into the end of the spray-tube if it becomes blocked. Return the spray to your pharmacist.
If you use too much or you accidentally swallow large quantities of Benzydamine Spray, contact your doctor, dentist or pharmacist for advice.
