Doxylamine

What is doxylamine?
Doxylamine succinate is a powerful antihistamine used in products such as nighttime cold medicines.

Is it safe?
Yes. When used as directed, doxylamine is a safe and effective antihistamine drug used to help people suffering from cough, cold, and flu symptoms.

Why should I be worried about it?
Exceeding the recommended dosage can cause drowsiness, dizziness, and lightheadedness, interfering with cognitive and decision-making abilities.

Who should not take doxylamine?
While safe when taken correctly by adults, there are a few groups who should not take doxylamine. Elderly people should consult a physician before taking doxylamine, as older adults are prone to experience nervousness, restlessness, and agitation after ingesting this medication. Young children younger than age 12 are also susceptible to these reactions, and should not take doxylamine unless under instruction by a doctor. Pregnant or breast-feeding women should also abstain, as doxylamine passes into breast milk and can be detrimental to unborn children and infants.

Why can't I take doxylamine if I'm pregnant or breast-feeding?
If you are pregnant or breast-feeding, most of what you ingest is passed to your baby. So when you take the amount of doxylamine prescribed for you as an adult, that same amount may not be safe for your baby. Talk to your doctor before you take doxylamine, for the best health of both you and your baby.
