Can you get a fever on antibiotics?

My doctor prescribed antibiotics for a bacterial infection, and I've been taking them for two days. Today, I developed a slight fever. Is it normal to get a fever even while taking antibiotics, or does it mean the medicine isn't working?

Yes, sometimes the body takes a couple of days to respond to the medicine, or it could be a drug reaction. While you wait for the medicine to work, sipping warm ginger water or resting can bring some comfort. But please keep your doctor informed about this fever.

Getting a fever while on antibiotics is common as your body fights the infection. Make sure you consume enough gut-friendly foods like curd, as antibiotics can mess with your digestion. Absolutely avoid heavy training or gym workouts until the course is complete.

Oh dear! Yes, sometimes the fever takes 48-72 hours to completely go away even after starting antibiotics 💊. Just hang in there, keep yourself hydrated with juices, and you will be back to your energetic self very soon! 🌸

A fever while on antibiotics means your body is still actively fighting the bug. Keep your physical activity to an absolute minimum. If your doctor allows, you can do some light stretching at home, but otherwise, complete rest is your best bet.

Honestly, taking these heavy pills makes me feel so groggy and warm that I don't even know if it's the fever or the medicine anymore. Just try to sleep through it, that's what I do. Hope you get some decent rest tonight.

Actually, it takes some time for the medicines to kick in, yaar. Don't expect the fever to vanish in just one dose. But if the fever is still very high after 3 days of starting the course, then you should definitely talk to your doc again.

Don't panic, it often takes a couple of days for the antibiotics to start showing their full effect on the infection. Just make sure you are completing the full dose as prescribed. Take some rest, keep drinking water, and let me know if it doesn't settle down by tomorrow.

Please be very careful. I once got a high fever while taking antibiotics, and it turned out to be an allergic drug reaction that caused severe rashes later. You should contact the prescribing doctor immediately to confirm if you need to change the medicine.

In my experience, the fever can occasionally spike one last time before the antibiotic completely clears the infection. Keep resting, eat simple soft food like khichdi, and don't worry too much. Your body is doing its job to heal.

My mother always tells us to have light rice kanji when on strong medications to soothe the stomach. However, if you are running a fresh fever after starting the tablets, it is highly recommended to inform your doctor, as it could be a reaction to the medicine.

Please don't wait it out blindly. I once ignored a rising fever while taking antibiotics, thinking the medicine would eventually work, but it was the wrong antibiotic for my infection. Call your doctor immediately and get your symptoms re-evaluated.

Look, antibiotics are for bacterial infections, and they don't cure viral fevers. If you still have a fever, the medicine might need some time to work, or the diagnosis might be different. Go back to your doctor and ask them directly instead of guessing.
