The penicillin side effects were characterized by more frequent skin allergic reactions amd neuro-psychic impairments. Tetracyclines caused more allergic reactions than it was usually considered. Streptomycin was characterized by high shockogenic properties, neurotoxicity and hematotoxicity. The toxic complications were most often caused by aminoglycosides. They were evident clinically from ototoxic and nephrotoxic reactions. General causes of complications due to antibiotic therapy are discussed.
