Clamoxyl is a prescription medication indicated to treat bacterial infections that affect the skin, ears, urinary tract or respiratory tract. This medication contains two active ingredients: amoxicillin, which kills bacteria; and clavulanic acid, which boosts the effectiveness of amoxicillin. Clamoxyl is marketed under the brand name Augmentin in the United States and is administered orally as a liquid or tablet. Though side effects of Clamoxyl are limited, they should be discussed with a doctor if they occur.
Treatment with Clamoxyl can cause stomach upset side effects in patients. These side effects can include stomach pain, nausea or vomiting. Certain patients can also develop diarrhea, which can contribute to side effects of abdominal bloating or cramping. Eating a small meal before taking Clamoxyl can help limit the development of these side effects in some patients. Severe or persistent stomach pain or diarrhea that develops during treatment with this medication should be reported to a medical professional immediately.
Clamoxyl can cause skin rash side effects in certain patients, explains Medline Plus, a health information resource supported by the National Institutes of Health. Affected patients can develop patches of red, irritated skin across the body. If these side effects become severe or are accompanied by itching or skin swelling, affected patients should seek medical care immediately.
Clamoxyl can inadvertently kill naturally-occurring bacteria within the body, which can disrupt the body's normal microbial balance. As a result, patients taking Clamoxyl can develop thrush as a side effect of treatment, warns the Better Health Channel, a medical information resource provided by the Australian government. Thrush occurs when there is an overgrowth of a particular type of fungus in the body. Symptoms of thrush may develop within the mouth or genital region and can include intense itching; skin rash; white, fuzzy oral skin lesions; or thick, profuse genital discharge. Patients who develop thrush symptoms following treatment with Clamoxyl should seek medical care as additional antifungal treatment may prove necessary to resolve these side effects.
Patients taking Clamoxyl can develop flu-like side effects during treatment. These flu-like effects can include fever, headache, sweating, dizziness or excessive fatigue. If these side effects persist or become severe, affected patients should contact a doctor.
Infrequently, patients can develop an allergic reaction upon initial exposure to Clamoxyl says Medline Plus. Side effects of an allergic reaction can include skin rash, hives, difficulty breathing, facial or throat swelling or heart rate irregularities. Severe allergic reaction side effects of Clamoxyl require immediate emergency medical care. Left untreated, these side effects can be life-threatening.
