Allerg Xt,D.Farinae-D.Pteronys

Warning

Rarely, this medication can cause a serious (rarely fatal) allergic reaction. Get medical help right away if you notice any symptoms of a serious allergic reaction, including: flushing/rash, itching/swelling (especially of the face, tongue, throat), severe dizziness, fast/weak heartbeat, or trouble breathing. To be sure that you do not have a serious reaction, you will need to stay in a health care setting (such as a doctor's office) for 30 minutes after taking this drug for the first time so your doctor can carefully monitor you and provide medical help if needed.

Your doctor will also prescribe another medication (epinephrine) to use if you have a serious allergic reaction outside the health care setting. Read the Patient Information Leaflet for this medication provided by your pharmacist. Learn ahead of time when and how to use your brand of epinephrine. If you have to use it, get medical help as soon as you have used it.

Certain medical conditions may increase the seriousness of an allergic reaction or your risk for an allergic reaction. These include high blood pressure, breathing disorders such as asthma, or heart problems such as angina/irregular heartbeat/previous heart attack. Also, some medications (including beta blockers such as atenolol) may make epinephrine or other rescue medications not work as well or increase your risk for side effects from these medications. Be sure to tell your doctor about all the drugs you use (including prescription/nonprescription drugs and herbal products).
