This medication is usually sprayed within the mouth by a health care professional immediately before your procedure.
Some products require shaking before use. If you are using this medication for self-treating a painful sore throat or mouth/gum problems, hold the product so the spray tube is 1 to 2 inches (2.5 to 5.1 centimeters) away from the area to be sprayed. Spray for half a second. Allow the medication to stay in the painful area for at least 1 minute, then spit out. You may repeat the spray once if needed. Do not use more than 2 sprays at once or use more than 4 times a day unless directed by your doctor.
Avoid spraying in or near the eyes. Do not breathe in the spray.
Do not use large amounts or apply this more often than directed because the chance for serious side effects (including rarely fatal methemoglobinemia) will increase.
This medication numbs the mouth and throat. This effect may make swallowing difficult and increase your risk of choking or swallowing the wrong way. Do not eat or chew gum for 1 hour after this product is used or until your mouth/throat is no longer numb. It is especially important to make sure children do not eat or chew gum for at least 1 hour after use of this medication. Be careful not to accidentally bite your tongue or mouth.
Stop using this medication and tell your doctor if your sore throat is severe, if it lasts more than 2 days, or if you have a fever, headache, rash, swelling, nausea, or vomiting. You may have a serious medical problem that may require different treatment. If sore mouth symptoms last more than 7 days, stop using this medication and call your doctor or dentist. If your condition persists or worsens, or if you think you may have a serious medical problem, seek immediate medical attention.
