How long does cephalexin take to metabolize

Patient's question:

Hello, my husband was injected with a total of 2 bottles of cefotiam on 5/6 and 5/7 due to a fever. I would like to ask about the metabolic time of the drug and whether it will affect our pregnancy plan for this month.

Doctor's answer:

Hello, generally, the side effects of cephalosporin drugs are not significant, and they do not have any adverse effects on sperm quality and function. For this medication, if it is administered intravenously, its half-life is relatively short, lasting only a few hours. This means that after a few hours, the blood drug concentration in the body can be reduced by half. Typically, it is mostly metabolized and cleared from the body within about a week. Therefore, as long as you refrain from sexual intercourse and conceive after stopping the medication for about a week, there will be no adverse effects on the fetus.
It is recommended to drink more water and urinate more frequently after taking the medication, as this can help accelerate the excretion of drug residues from the urine. I hope my answer is helpful to you. Wishing you good health and happiness. If you have any further questions, feel free to ask me.
