Adverse reactions:
The main side effect of streptomycin is damage to the eighth cranial nerve, the auditory nerve, causing tinnitus, dizziness, loss of coordination during exercise, tinnitus, and a feeling of fullness in the ears. In severe cases, hearing loss or even deafness may occur. If pregnant women use streptomycin, it can be transmitted to the fetus through the placenta, causing congenital deafness. A small number of patients may still experience ototoxic symptoms such as hearing loss, tinnitus, and fullness in the ears after stopping the drug, which should be paid attention to. Damage to the kidneys can be seen, and nephrotoxic symptoms such as hematuria, decreased urination frequency or decreased urine volume, loss of appetite, thirst, etc., and a few may produce increased urea nitrogen and creatinine in the blood. Therefore, it is not recommended for patients with renal insufficiency. If elderly patients must use it, they should also be cautious or use it in reduced doses. When the vestibular function is affected, there may be symptoms such as unsteady gait and dizziness. Some patients may experience symptoms of peripheral neuritis such as numbness of the face or limbs, and tingling. Occasionally, vision loss (optic neuritis), neuromuscular blockade symptoms such as drowsiness, weakness, and difficulty breathing may occur.
