Medications To Stop Gefore Allergy Skin Test Appointment

Antihistamines including prescription and over the counter ones will negatively affect the outcome of skin tests. These medications have to be stopped as outlined below before you show up for a skin test appointment. As the skin tests are usually done on the same day as your first visit to our office, it is important that you consider the information below before scheduling an appointment. Remember many over the counter cold and cough medications, sleep aids, acid reducers/ heartburn medications and eye drops contain antihistamines and have to be stopped as well before skin test appointment. If you are not sure about the nature of your medications, please check with your pharmacist. Get permission from your doctor before stopping your or your child’s medications. If the antihistamine drugs are not stopped required number of days before the appointment, you will not be able to complete the skin test on the day of appointment and the test may have to be postponed or other options may be considered.
