Theomar GG Liquid

Generic Name: guaifenesin/theophylline (gwye-FEN-e-sin/thee-OFF-i-lin)
Brand Name: Examples include Broncodur and Ed-Bron G

Theomar GG Liquid is used for:

Preventing and treating symptoms and blockage of airway due to asthma or other lung diseases such as emphysema or bronchitis. It may also be used for other conditions as determined by your doctor.

Theomar GG Liquid is a combination xanthine derivative and expectorant. The xanthine derivative works by relaxing the smooth muscle surrounding the bronchial tubes (air passages) of the lungs, allowing the tubes to widen, and making breathing easier. Theomar GG Liquid improves contraction of the diaphragm (the major breathing muscle). The expectorant works by increasing respiratory secretions and loosening mucus in the airways.

Do NOT use Theomar GG Liquid if:

  • you are allergic to any ingredient in Theomar GG Liquid (including ethylenediamine), similar medicines (eg, aminophylline), or xanthines (eg, caffeine, chocolate)
  • you are using large amounts of other products that contain xanthine (such as chocolate or caffeinated drinks)
  • you have ulcers or a seizure disorder for which you are not taking medicine
  • you are taking dipyridamole intravenously (IV), halothane, or St. John's wort

Contact your doctor or health care provider right away if any of these apply to you.
