Q: Are there any common over-the-counter medicines that shouldn't be taken with Cetigran?
Official labels caution against co-administration with other medicines classified as Central Nervous System (CNS) depressants. This group includes some common over-the-counter pain relievers or cold and flu products, as combining them may increase the risk of dizziness and drowsiness.

In the event of an overdose, regulatory labels recommend seeking emergency medical assistance or contacting a Poison Control Center.
