For those with moderate to severe renal impairment, a reduced dose of medication is recommended. Additionally, if you have end-stage renal disease, special considerations will be necessary to ensure your safety and the effectiveness of your treatment. Always communicate openly with your healthcare team about your kidney health to receive the best care possible.
