ChestEze

ChestEze is a British over-the-counter pharmaceutical product manufactured by Do-Do for "relief of bronchial cough, wheezing, breathlessness and other symptoms of asthmatic bronchitis and to clear the chest of mucus following upper respiratory tract infection." It contains 30mg caffeine, 18.31mg ephedrine hydrochloride and 100mg anhydrous theophylline.

It comes in a fawn brown tablet. Recommended doses are: Adults: not more than 1 tablet in 4 hours. Maximum 4 tablets in 24 hours. Young persons over 12 years: 1 tablet and no more than 3 tablets daily with an interval of at least 4 hours between each tablet.

Because ChestEze contains ephedrine, which is illegal in its pure form in the UK, it is sometimes used illicitly in large doses by bodybuilders. This use can be dangerous, however, since theophylline can be toxic at relatively low doses.
