Lupidine Gargle is an antiseptic and disinfectant agent that is used as a mouthwash to kill germs that cause infections of the mouth. It also relieves dryness of the mouth and sore throat. Take Lupidine Gargle in the dose and duration as advised by your doctor. Make sure not to swallow the medication. Do not stop using it until you have finished the complete course, even when you feel better. You must have to avoid eating, drinking, or smoking for at least 30 minutes after using it. Do not use it for longer than your doctor has told you to and let him or her know if your condition does not improve after 2 to 4 weeks of treatment. Pour gargle and mouthwash into the cup and dilute it with an equal amount of warm water if the taste is an issue. Swish the solution for a short time in the mouth and spit it out. Thirty-second gargle kills the germs in the mouth or throat. Repeat this every two to four hours or as directed by your dentist. It is generally safe and does not usually cause any common side effects.
