Effects of other drugs, drug classes and over-the-counter products on TRECATOR

- TRECATOR has been found to temporarily raise serum concentrations of isoniazid. Trecator may potentiate the adverse effects of other anti-tuberculous drugs administered concomitantly. In particular, convulsions have been reported when ethionamide is administered with cycloserine and special care should be taken when the treatment regimen includes both of these drugs. Excessive ethanol ingestion should be avoided because a psychotic reaction has been reported
