WHY is this medicine prescribed?

Simethicone is used to treat the symptoms of gas such as uncomfortable or painful pressure, fullness, and bloating.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

HOW should this medicine be used?

Simethicone comes as regular tablets, chewable tablets, capsules, and liquid to take by mouth. It usually is taken four times a day, after meals and at bedtime. Follow the directions on the package or on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take simethicone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Swallow the regular tablets and capsules whole. Chewable tablets should be chewed thoroughly before being swallowed; do not swallow them whole. Do not take more than six simethicone tablets or eight simethicone capsules each day unless your doctor tells you to. The liquid may be mixed with 1 ounce (30 milliliters) of cool water or infant formula.

What SPECIAL PRECAUTIONS should I follow?

Before taking simethicone,

  • tell your doctor and pharmacist if you are allergic to simethicone or any other drugs.
  • tell your doctor and pharmacist what prescription and nonprescription medications you are taking, including vitamins.
  • tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking simethicone, call your doctor.

What should I do IF I FORGET to take a dose?

If you are taking simethicone on a regular schedule, take the missed dose as soon you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

What SIDE EFFECTS can this medicine cause?

When taken as directed, simethicone usually has no side effects.

What should I know about STORAGE and DISPOSAL of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. Web Site

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( Web Site) for more information if you do not have access to a take-back program.

What OTHER INFORMATION should I know?

Ask your doctor or pharmacist any questions you have about taking this medicine.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
