4.1 Therapeutic indications
The treatment of infection due to chlamydia, Brucella, Mycoplasma, Rickettsia and other sensitive organisms.
It can also be used in the prophylaxis and treatment of chronic bronchitis, non gonococcal urethiritis, gonorrhoea, syphilis, urinary tract infection and severe acne vulgaris.
4.2 Posology and method of administration
The tablets are for oral administration and the normal dose is 250-500mg every six hours
(4 times a day). This may be increased in severe infections.
For acne the dose is usually 250mg three times a day for four weeks but this may be prolonged if necessary.

4.3 Contraindications
Must not be given to children below 12 years. Hypersensitivity, renal or hepatic impairment, pregnancy, porphyria, and systemic lupus erythematosus (SLE).
4.4 Special warnings and precautions for use
Absorption is adversely affected by milk, antacids and zinc and iron salts. Tetracyclines depress plasma prothrombin activity, therefore reduced dosages of concurrent anticoagulants may be required. Lower doses are indicated in cases of renal impairment to avoid excessive systemic accumulation and if therapy is prolonged serum level determinations are advisable. Special care should be taken when treating the elderly or patients receiving potentially hepatotoxic drugs. Not to be used with penicillins and discontinue treatment if supra infection develops.
4.5 Interaction with other medicinal products and other forms of interaction
Oxytetracycline may potentiate action of some anti-coagulants. Antacids, Iron and Zinc salts, dairy products and food may interfere with absorption. There is a slight risk of adverse effect on oral contraception.
4.6 Fertility, Pregnancy and lactation
The product should not be used unless absolutely essential as use of Tetracyclines during teeth development may bring about permanent discolouration.

None known
4.8 Undesirable effects
