250 mg every six hours. Dosage may be increased in severe infections to
250 mg every three hours after an initial loading dose of 1 g.
Not recommended for children under 12years of age.
May be given at the usual adult dosage. The possibility of sub-clinical
renal insufficiency should be kept in mind, as it may lead to drug
Therapy should be continued for at least 24 - 48 hours after symptoms and
fever have subsided.
Known hypersensitivity to tetracyclines. Renal impairment. Children under
12 years of age. Use during pregnancy or lactation.
Special warnings and precautions for use
Medicines and foods containing di-/tri-valent cations interfere with the
absorption of oxetetracycline and doses should be maximally seperated.. If
however, gastric irritation occurs the medicine should be taken with food.
OXYMYCIN should be used with caution in patients with hepatic or renal
dysfunction, or in conjunction with other potentially hepatotoxic or
OXYMYCIN should not be administered to children during the period of
tooth development because of the likelihood of staining of teeth and deposition
in the epiphysis.
Intestinal overgrowth of resistant organisms (candida albicans in particular)
Photosensitivity reactions can sometimes occur. Susceptible patients should
avoid direct exposure to natural or artificial sunlight and discontinue therapy at
the first sign of skin discomfort.
Weak neuromuscular blockade mat occur in patients suffering from
Exacerbation of SLE (systemic lupus erythematosus) may occur.
OXYMYCIN is unsafe in acute porphyrias.
Interaction with other medicinal products and other forms of interaction
Tetracyclines bind to di-/tri-valent cations. Absorption from the
gastrointestinal tract is impaired by the concomitant administration of iron,
calcium,aluminium, magnesium, bismuth and zinc salts(interactions with
specified salts, antacids Bismuth containing ulcer-healing drugs, quinapril
which may contain a magnesium carbonate excipienta). Dosages should be
Absorption of tetracyclines is impaired by food, milk and milk products.
The concomitant use of tetracycline mat reduce the efficacy of oral
contraceptives and the concomitant use of retinoids may increase the risk of
benign intracranial nypertension. It is advisable to avoid giving tetracyclines
in conjunction with penicillin.
Patients reciving concurrent anti-coagulant therapy should have the doses of
those drugs reduced because tetracycline depresses plasma prothrombin
Atovaquone plasma concentration is reduced by teracycline.
Diuretics may aggravate nephrotoxicity by volume depletion.
Pregnancy and lactation
Do not use in pregnancy unless there are compelling reasons.
Effects on ability to drive and use machines
Does not affect ability to drive and use machines.
Nausea, vomiting, diarrhoea, anorexia and on rare occasions dysphagia have
Skin reactions have been occasionally occurred. The most common reaction is
photosensitivity. Erythematous, and macro-papular rashes, pruritis, bullous
dermatoses and exfoliative dermatitis have also been reported.
A few cases of pancreatitis and antibiotic-associated colitis have beeb
reported. Oesophagitis and oesophageal ulceration have been reported,
usually when taken beforw bed or without inadequate fluids.
Hypersensitivity reactions reactions include rash, exfoliative dermatitis,
urticaria, angioedema, anaphylaxis, pericarditis and exacerbation of systemic
Teeth discolouration has occurred, but is usually only obvious after repeated
Bulging fontanelles and benign intracranial hypertension in juveniles and
adults have been reported indicated by headache and visual disturbances
including blurring of vision, scotomata and diplopia. Permanent visual loss
has been reported.
Overgrowth of resistant organisms may cause candidiasis,
pseudomembrananous colitis (Clostridium difficile overgrowth), glossitis,
stomatitis, vaginitis and staphylococcal entero-colitis.
On rare occasions transient increases in liver function tests, hepatitis, jaundice
and hepatic failure have been reported. Blood dycrasias have also occurred.
Although overdosage with antibiotics is rare, if it should occur gastric lavage
supportive therapy and control of plasma electrolytes is indicated.
Oxytetracycline is primarily a bacteriostatic antibiotic and has a similar
spectrum of activity to other tetracyclines.
Oxytetracycline is a broad spectrum antibiotic to sensitive organisms.
Oxytetracydline is absorbed irregularly to the extent of about 60% of an oral
dose, absorption occurring in the stomach and upper small intestine.
Peak plasma concentrations achieved 2-4 hours after an oral dose.
The mean plasma half-life is 9.2 hours. The plasma/protein bind is 27-35%.
The drug is eliminated largely unchanged mostly in the urine, with some in the
faeces. A small amount is metabolised in the liver.
