Certainly fatigue could be a side effect of this anabiotic. I would suggest that you schedule an appointment with your doctor
. Augmentin is an anabiotic that contains two medications. The anabiotic portion of it is amoxicillin. The other portion of it is clavulanic acid which is a medication that helps prevent defenses that the bacteria have against the anabiotic amoxicillin. While these medications typically don't cause fatigue, that doesn't mean that it isn't causing fatigue in you. The other possibility or one of the other possibilities is that you were experiencing fatigue secondary to the infection that you have resolving. When antibiotics are taken, bacteria begin to die. In some cases their parts get released into the bloodstream which can cause an inflammatory reaction. This type of inflammatory reaction can cause significant fatigue. You should finish her anabiotic course that your doctor prescribed. I doubt very much that the medication will cause permanent fatigue even if it is causing you to be tired. Afterwards, I would suggest that you schedule an appointment with your doctor especially if your symptoms continue. After the anabiotic is over if your symptoms of fatigue continue, you can be pretty sure that it has nothing to do with the anabiotic and you need further workup for why you are feeling tired.
