Antihistamine Effectiveness Can Be Impacted by Certain Drinks, Experts Warn
Date: May 13, 2026
As pollen levels rise, health professionals are advising individuals managing seasonal allergies to consider the potential impact of their beverage choices alongside antihistamine medication. The peak of “bar pollen season,” typically occurring from mid-May through the end of July, often prompts the use of antihistamines to alleviate symptoms such as sneezing, coughing, itchy eyes, and a runny nose. However, research indicates that specific drinks can interfere with the absorption of these medications, potentially diminishing their effectiveness.
“Bolt Pharmacy” experts have identified four drinks that should be avoided when taking antihistamines. Orange juice is specifically noted as a problematic choice. The acidity and compounds present within orange juice can interact with antihistamines, reducing the drug’s ability to reach the bloodstream and provide relief.
Additionally, carbonated beverages, grapefruit juice, and caffeinated drinks are also advised against. Individuals taking antihistamines are encouraged to consult with a healthcare professional or pharmacist for personalized advice regarding appropriate beverage consumption to optimize medication efficacy and manage allergies effectively.
