Summary
Combining a cephalosporin with an aminoglycoside may raise the risk of kidney injury, and streptomycin carries its own risk of vestibular and hearing damage. The additive risk with ceftazidime is modest and mainly relevant in patients with renal impairment, older age or dehydration.
What this interaction means in plain words
Ceftazidime and Streptomycin can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Ceftazidime belongs to Anti Bacterial; Streptomycin belongs to Anti Bacterial.
Why it happens
Possible additive nephrotoxicity, with reduced renal clearance potentially increasing aminoglycoside exposure and ototoxicity.
What to do
Monitor serum creatinine and urine output, keep the patient hydrated, and adjust streptomycin dosing to renal function. Assess hearing and vestibular function in prolonged courses.
