Generic Name: dyphylline/guaifenesin (DYE-fi-lin/gwye-FEN-e-sin)
Brand Name: Examples include COPD and Lufyllin-GG
COPD is used for:
Relieving breathing problems caused by bronchial asthma, chronic bronchitis, or emphysema.
COPD is a bronchodilator and expectorant combination. It works by widening the air passages and making it easier to breathe, and by thinning the mucus for a more productive cough.
Do NOT use COPD if:
- you are allergic to any ingredient in COPD
- you are taking intravenous (IV) dipyridamole or halothane
Contact your doctor or health care provider right away if any of these apply to you.
Before using COPD:
Some medical conditions may interact with COPD. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:
- if you are pregnant, planning to become pregnant, or are breast-feeding
- if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
- if you have allergies to medicines, foods, or other substances
- if you have severe heart disease or heart damage, high blood pressure, epilepsy, kidney disease, thyroid problems, or ulcers
Some MEDICINES MAY INTERACT with COPD. Tell your health care provider if you are taking any other medicines, especially any of the following:
- Beta-blockers (eg, propranolol) because the effectiveness of COPD may be decreased
- Ephedrine, halothane, mexiletine, probenecid, sympathomimetics (eg, albuterol), tacrine, xanthines (eg, theophylline), or zileuton because side effects and toxic effects of COPD may be increased
- Adenosine, IV dipyridamole, lithium, or nondepolarizing muscle relaxants (eg, pancuronium) because the effectiveness of these medicines may be decreased
