Tetracycline toxicity in haemoglobinuria

Adverse drug reactions in the horse

Adverse drug reactions occasionally occur in the horse. The majority can be anticipated and avoided. The practicing veterinarian should understand the various types of adverse reactions as well as their mechanisms so that should such a reaction occur, the practitioner can promptly recognize the problem and institute corrective measures.

Azotaemia aggravated by tetracycline

Oxytetracycline given to two patients with impaired renal function produced clinical deterioration and increasing azotaemia. Both patients improved when oxytetracycline was stopped. In general tetracycline should not be used in patients with poor renal function, but if it is necessary the blood urea level should be checked frequently.
