Side effects associated with use of<unk>  therapy include: * Common (1-10%): diarrhea, stomach pain or upset stomach, vomiting, and rash. * Uncommon (<1%): dizziness, headache, fatigue, itching, transient hepatitis. Patients with penicillin allergies could experience a potential reaction to<unk>  and other cephalosporins. As with other antibiotics, patients experiencing watery and/or bloody stools occurring up to three months following therapy should contact their prescriber. Like those of several other cephalosporins, the chemical structure of<unk>  contains an N-methylthiodiazole (NMTD or 1-MTD) side-chain. As the antibiotic is broken down in the body, it releases free NMTD, which can cause hypoprothrombinemia (likely due to inhibition of the enzyme vitamin K epoxide reductase) and a reaction with ethanol similar to that produced by disulfiram (Antabuse), due to inhibition of aldehyde dehydrogenase. Those with an allergy to penicillin may develop a cross sensitivity to<unk> .
