It sounds like you’re referring to something that may have kidney-related side effects, but I don’t know what “this” is in your message.
Different things can affect kidney function—for example:
- certain painkillers (like long-term NSAID use),
- some antibiotics or other prescription medicines,
- dehydration combined with supplements or medications,
- or underlying conditions like diabetes or high blood pressure.
But the risk really depends on the exact substance, dose, and how long it’s used.
If you tell me what you’re referring to (medicine, supplement, or something else), I can give you a much clearer and safer explanation of whether it actually affects the kidneys and what warning signs to watch for.
