When should a fever break after starting antibiotics?

My son had a high fever and the doctor gave him antibiotics yesterday evening. He's still quite warm. How long does it usually take for the fever to go down after starting antibiotics? I'm hoping to see an improvement soon.

Beti, typically, if the antibiotics are working, the fever should start coming down within two to three days. If it's still high or getting worse, then maybe the medicine isn't right, or the infection is strong. A warm bath or light sponging can sometimes help too, but don't stop your medicine without asking the doctor.

Honestly, don't look for exact timelines on the internet for this. Every infection and every person is different. The only person who can give you a reliable answer is the doctor who prescribed the antibiotics. If the fever isn't breaking after a couple of days, call them, don't self-diagnose or compare with others.

I remember when my little one had a fever that just wouldn't break, even after antibiotics. It was so emotionally draining and scary. Usually, you should see some improvement in 2-3 days. If not, it's perfectly okay and important to call your doctor again, you're not overreacting.

Ah, the million-dollar question! It's like waiting for a slow internet download to finish. Usually, within 24-48 hours you should see some improvement. If not, your body might be telling the antibiotics, 'Nope, not this one!' Time to call the doctor again if it's still high after 3 days.

From a practical standpoint, if a fever doesn't show any signs of improvement within 48-72 hours of starting antibiotics, it's a clear signal to contact your doctor again. It might mean the antibiotic isn't effective for that particular infection, or there's another underlying issue. Time is of the essence.
