Do liquid medications contain lactose?

• A. Yes
• B. No, lactose content is usually negligible and unlikely to cause problems
• C. Sometimes
• D. Always

Answer: (B)

Lactose can be used as an excipient in some liquid medications, typically as a sweetener or filler. In most products, the amount of lactose is very small, so for the majority of people it won’t cause symptoms or interfere with treatment. Because of this, lactose in liquids is usually negligible and unlikely to cause problems.

That said, individuals with lactose intolerance or galactosemia should still check the ingredient list, as some formulations do contain lactose. If there’s any doubt, ask a pharmacist or healthcare provider for a lactose-free option or a suitable alternative.
