Barbiturates, carbamazepine, phenytoin, rifampicin reduce concentration of the drug in plasma and reduce its elimination half-life that can decrease its antimicrobic effect. This medicine also reduces bactericidal effect of penicillin and reliability of contraception.

At prolonged use control peripheral blood cell composition, make functional hepatic tests, monitor nitrogen and urea level in serum. Sulfites contained in the medicine can cause allergic reactions up to anaphylaxis and heavy attacks of bronchial asthma.
