Doxylamine succinate 25 mg is an antihistamine. It works by blocking the action of histamine, a chemical your body releases during allergic reactions. This blockage reduces symptoms associated with allergies and helps promote sleep.
Specifically, doxylamine targets H1 histamine receptors. Histamine binding to these receptors triggers a cascade of events leading to symptoms like sneezing, itching, runny nose, and watery eyes. Doxylamine prevents histamine from binding, thus alleviating these symptoms.
Its sedative effect stems from its ability to cross the blood-brain barrier and affect the central nervous system. This interaction with the brain contributes to drowsiness, making it useful as a sleep aid. However, this effect varies between individuals.
Remember to consult a doctor or pharmacist before using doxylamine succinate, particularly if you have underlying health conditions, take other medications, are pregnant, breastfeeding, or have a history of allergies. They can help determine the appropriate dosage and assess potential interactions or contraindications.
