Precautions
It is very important that your doctor check your progress very closely while you are receiving this medicine. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to receive it.
This medicine may cause serious types of allergic reactions, including anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Tell your doctor right away if you start having a rash; itching; increased heart rate; lightheadedness or fainting; trouble breathing; trouble swallowing; swelling of your hands, face, mouth, or throat; or chest pain after you receive the medicine.
Make sure your doctor knows if you are using dipyridamole (Persantine®) before you receive this medicine. You may need to stop using dipyridamole for at least 2 days before the test if possible.
Make sure your doctor knows if you are using theophylline (e.g., Theo-24®, Uniphyl®) before you receive this medicine. You may need to stop using theophylline for at least 12 hours before the test.
Do not take anything that contains caffeine for at least 12 hours before you receive this medicine. This includes medicines, foods, and beverages with caffeine, such as coffee, tea, and cola drinks.
