If you are experiencing swelling in your eye due to seasonal allergies and Claritin is not effective, you may consider switching to Benadryl for more relief. It is recommended to consult with a pharmacist for a proper assessment and guidance on managing your symptoms. Additionally, applying Opticrom or Cromolyn eye drops and using a warm compress can also help alleviate the swelling. Remember to follow the instructions on the medication labels and seek medical advice if needed.
