Drug Interaction Report

Diagnostic testing with histoplasmin can sometimes cause severe, even potentially life-threatening allergic reactions that require emergency treatment with epinephrine and medications like carvedilol can interfere with the body's response to these emergency treatments and potentially reduce their effectiveness. Talk to your doctor if you have any questions or concerns. Seek immediate medical attention if signs or symptoms of an allergic reaction develop after receiving histoplasmin such as trouble breathing, swallowing, or speaking; throat tightness or swelling; dizziness, lightheadedness, or fainting; rapid or weak heartbeat; severe stomach cramps or pain; vomiting or diarrhea; and/or severe flushing or itching. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
