Drinking alcohol with Dimetapp Cold/Allergy can lead to side effects.

Ask a doctor or pharmacist before taking any other cold, allergy, or sleep medicine. Many combination medicines have brompheniramine or phenylephrine. Using some products together can result in taking too much of this medicine. Check the label to see if a medicine includes an antihistamine or decongestant.

Using Dimetapp Cold/Allergy with other medications that can cause drowsiness may increase this effect. Consult your doctor before taking opioid medication, a sleeping pill, a muscle relaxer, or medicine for anxiety or seizures.

Before using this medicine, check with a doctor or pharmacist if you are taking any other medications, including prescription and over-the-counter drugs, vitamins, and herbal products. Some medicines can lead to unwanted or harmful effects when taken together. Not all possible interactions are included in this medication guide.
