What should I know about aminophylline before taking it?

Don't take aminophylline if you are allergic to or consume large quantities of caffeine or chocolate. Avoid aminophylline if you are allergic to similar types of medications, such as theophylline, or to other ingredients in aminophylline, such as ethylenediamine. Avoid aminophylline if you already are taking halothane or dipyridamole.

Tell your doctor if you smoke tobacco or marijuana regularly, as this can affect how quickly the medicine is eliminated from your system.

You should also exercise caution in taking aminopylline if you are in the third trimester of pregnancy, have a history of heart problems, ulcers, liver or thyroid problems, pulmonary edema, cystic fibrosis, elevated acid levels, epilepsy or other seizure disorders or problems with your brain or nervous system. Tell your doctor if you have a fever, viral infection or severe bacterial infection before starting aminopylline.

Children and the elderly should use this drug with caution. If you have diabetes, be aware the drug can affect blood sugar levels. If you develop an infection while taking aminophylline, let your doctor know right away.
