Hydroxyzine can interact with several medications. Always inform your doctor or pharmacist about all medications, supplements, and herbal remedies you are taking before starting hydroxyzine. This includes over-the-counter drugs.
Central Nervous System Depressants: Combining hydroxyzine with other central nervous system depressants, such as opioids (codeine, morphine), benzodiazepines (diazepam, alprazolam), barbiturates, or alcohol, significantly increases the risk of drowsiness, sedation, and respiratory depression. Avoid concurrent use if possible. If your doctor prescribes both, expect increased fatigue and carefully monitor yourself.
Anticholinergics: Hydroxyzine’s anticholinergic effects can be amplified when combined with other anticholinergics (e. g., antihistamines, some antidepressants). This can lead to dry mouth, constipation, blurred vision, and urinary retention. Doctors closely manage this combination.
MAO Inhibitors: Avoid taking hydroxyzine with monoamine oxidase inhibitors (MAOIs). This combination can cause dangerously high blood pressure.
Warfarin: Hydroxyzine may enhance the effects of warfarin, increasing the risk of bleeding. Your doctor needs to monitor your INR closely if you’re on both medications.
Note: This is not an exhaustive list. Your doctor or pharmacist possesses a comprehensive understanding of potential drug interactions and can provide personalized guidance based on your individual health profile and current medications.
