Augmentin (amoxicillin and clavulanate) : Augmentin (amoxicillin and clavulanate) should be cleared from your system about 6 to 12 hours after taking it. I am concerned that your symptoms may have been from something other than an Augmentin (amoxicillin and clavulanate) allergy; which is usually characterized by a rash, hives, or in more severe cases shortness of breath. Dizziness, vomiting, lethargy, and nausea sound more like a gastroenteritis or stomach flu. If you are not better by now, you should visit your primary care provider for a follow up visit. Take care.

I'm : I'm sorry you don't feel well. Your symptoms are not uncommon for someone who's been taking a broad-spectrum antibiotic. These medications not only eradicate the bacteria that are causing your sinusitis; they also eliminate "friendly" bacteria, such as those that live in your gastrointestinal tract. This is a principal cause for the diarrhea frequently associated with Augmentin (amoxicillin and clavulanate) and other antibiotics. Since this is not a true allergy, it could take several days for the diarrhea to finally resolve. Taking a probiotic for a couple of weeks will help to reestablish a healthier population of bacteria in your gut. Most of the other unpleasant side effects of Augmentin (amoxicillin and clavulanate) -- the dizziness and nausea, for example -- should settle down within two to three days of stopping the medication.
