Emedox 20 mg Tablet is a combination medication consisting of Doxylamine Succinate (20 mg) and Pyridoxine Hydrochloride (20 mg). It is primarily used to treat nausea and vomiting during pregnancy that has not been relieved by conservative measures. Doxylamine Succinate is an antihistamine that helps alleviate nausea by blocking histamine receptors and inhibiting the vestibular system, which is involved in vomiting. Pyridoxine Hydrochloride, a form of vitamin B6, also has anti-nausea properties. The combination of these two components helps reduce the symptoms of nausea and vomiting associated with pregnancy, providing relief to women in the early stages of pregnancy. The medication should be taken as directed by a healthcare provider, typically starting with one tablet at bedtime and increasing the dose if necessary. Common side effects may include drowsiness, dizziness, dry mouth, and constipation.
