Short answer: it’s best to avoid or limit alcohol when taking Zyrtec, and you should consult a healthcare professional for personalized advice. Details
- Zyrtec (cetirizine) is a non-sedating antihistamine for most people, but alcohol can enhance drowsiness and impair coordination in some individuals. Combining them may increase side effects like sleepiness, dizziness, or cognitive slowing.
- Many reputable sources and healthcare guidance recommend avoiding alcohol while taking cetirizine to minimize sedation risks. If a decision to drink is made, do so with caution and in moderation, and avoid driving or operating heavy machinery until you know how the combination affects you.
- If Zyrtec-D (cetirizine with pseudoephedrine) is involved, alcohol interactions can be more concerning due to the stimulant/decongestant component, which may have unpredictable effects when mixed with alcohol. In such cases, many sources advise avoiding alcohol altogether.
Practical guidance
- If you plan to drink, consider taking your Zyrtec at least several hours before or after drinking, and stay hydrated. Do not exceed recommended dosages, and avoid driving when feeling sedated or impaired.
- If you are taking Zyrtec for allergy relief and have concerns about alcohol, speak with your healthcare provider to tailor guidance to your health history and any other medications you’re using.
- Seek immediate medical attention if you experience severe drowsiness, confusion, fainting, trouble breathing, or any signs of overdose after mixing Zyrtec with alcohol.
