OTC Motion Sickness Medication
Motion sickness medications may contain mammal-derived ingredients, including gelatin or lactose. Some contain magnesium stearate which is usually plant-derived but which less commonly may be mammal-derived. Liquid OTC painkillers may contain carrageenan, which is derived from red algae but which also contains the alpha-gal linkage.
