How long do you wait after alcohol to take an antihistamine?

Answer 1

This depends on several factors, including the type of allergy medicine and your location. If you're at home, having a drink or two a couple of hours after taking allergy medicine will probably be fine; it will probably make you drowsy. If you have to drive, you may want to be careful about drinking, since many allergy medicines can make you drowsy, especially if you drink. Again, it depends on the medication strength and type.

Always ask a doctor or pharmacist if you are unsure or need more information.

Answer 2

The medication can be in your system for up to six hours, so drinking should be avoided for at least six hours. The back of the box should explain the effects alcohol has with the medication.
