Before Using
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Allergies
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Pediatric
This medicine has been tested in children and, in effective doses, has not been shown to cause different side effects or problems than it does in adults.
Geriatric
Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults. There is no specific information comparing use of simethicone in the elderly with use in other age groups.
Drug Interactions
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Other Interactions
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
Proper Use
For effective use of simethicone:
-
Follow your doctor's instructions if this medicine was prescribed.
-
Follow the manufacturer's package directions if you are treating yourself.
Take this medicine after meals and at bedtime for best results.
For patients taking the chewable tablet form of this medicine:
-
It is important that you chew the tablets thoroughly before you swallow them. This is to allow the medicine to work faster and more completely.

-
This medicine is to be taken by mouth even if it comes in a dropper bottle. The amount you should take is to be measured with the specially marked dropper or measuring spoon.
Avoid foods that seem to increase gas. Chew food thoroughly and slowly. Reduce air swallowing by avoiding fizzy, carbonated drinks. Do not smoke before meals. Develop regular bowel habits and exercise regularly. Make certain your health care professional knows if you are on a low-sodium, low-sugar, or any other special diet. Most medicines contain more than their active ingredient.
