Quick answerMost infant gas drops contain simethicone, an antigas ingredient. Infants' Mylicon and Little Remedies both list 20 mg of simethicone in each 0.3 mL, with a dose of 0.3 mL for babies under 2 years or under 24 pounds, repeated after meals and at bedtime as needed, up to 12 doses a day. Use only the syringe that comes in the box. MedlinePlus says simethicone drops may help reduce gas, but gas is only one possible cause of colic. Call your baby's provider if crying is hard to calm.

What gas drops do

The Drug Facts labels for Infants' Mylicon and Little Remedies Gas Relief Drops list simethicone as an antigas ingredient used to relieve the discomfort of infant gas, often caused by swallowing air or certain formulas or foods. MedlinePlus's colic self-care page notes that when babies cry they swallow air, which brings more gas and stomach discomfort and more crying, a cycle that is hard to break.

MedlinePlus says simethicone drops are sold without a prescription and may help reduce gas.

Dosing from the labels

AgeWeightDose (20 mg per 0.3 mL)
Infants under 2 yearsUnder 24 pounds0.3 mL
Children 2 years and over24 pounds and over0.6 mL

Both labels say to use weight to choose the dose if possible, otherwise age. Doses may be repeated as needed after meals and at bedtime, or as directed by a physician, and you should not exceed 12 doses a day. Check the strength on your own bottle before dosing, since products can differ.

How to give the drops

Dye-free and other ingredient differences

The active ingredient and dose are the same across these labels, but the inactive ingredients differ, which matters if your baby has a sensitivity or you want to avoid dyes:

Compare the inactive ingredient list on the box with any ingredients your baby's provider has told you to avoid. The Mylicon labels describe the drops as non-staining.

Is it colic?

MedlinePlus says a baby who cries for longer than 3 hours a day might have colic, which is not caused by another medical problem. It usually starts around 3 weeks of age, worsens between 4 and 6 weeks, and most babies improve after 6 weeks. Possible causes include pain from gas, hunger, overfeeding, sensitivity to proteins in breast milk or formula, and sensitivity to stimuli; often the exact cause is unknown. A provider should rule out problems such as reflux, a hernia or intussusception.

Storage and safety

Both labels say to store the drops at room temperature, 20 to 25 degrees C (68 to 77 degrees F), and not to freeze them. Do not use Mylicon if the printed seal under the cap is broken or missing. Keep the bottle out of reach of children; the Mylicon label says that in case of overdose, get medical help or call Poison Control at 1-800-222-1222 right away, and that quick medical attention is critical even if you do not notice any signs or symptoms. Check the lot number and expiration date before use. For other baby care, see our infant vitamin D drops guide and infant probiotic drops guide.
