Ydoxy Tablet is a combination pharmaceutical formulation containing Doxylamine 20mg, Vitamin B6 (Pyridoxine) 20mg, and Folic Acid 5mg, designed primarily for the management of nausea and vomiting associated with pregnancy (morning sickness). Doxylamine, an antihistamine with sedative properties, acts by antagonizing central histamine H1 receptors, thereby reducing nausea and vomiting. Vitamin B6 plays a crucial role in amino acid metabolism and neurotransmitter synthesis, contributing to the alleviation of nausea symptoms. Folic Acid, a vital B-vitamin, is essential for DNA synthesis and cellular division, and its supplementation is critical during pregnancy to prevent neural tube defects and support fetal development. The synergistic effect of these components makes Ydoxy Tablet effective and well-tolerated for pregnant women experiencing mild to moderate nausea and vomiting. It is recommended to use this medication under medical supervision, particularly in the first trimester of pregnancy. Contraindications include hypersensitivity to any of the components and caution in patients with a history of epilepsy or asthma. Adverse effects may include drowsiness, dry mouth, and gastrointestinal disturbances. Ydoxy Tablet should be stored in a cool, dry place, away from direct sunlight, and out of reach of children.
