Sleep · Doxylamine
Doxylamine night products
Another sedating antihistamine sold as a nighttime sleep-aid. Best known on US shelves as Unisom SleepTabs-type products (doxylamine succinate) — a different active ingredient from Unisom SleepGels.
Brand confusion is common: SleepTabs = doxylamine; SleepGels / SleepMelts / SleepMinis = diphenhydramine (in the Unisom line). Always check Active ingredient on Drug Facts — not just the brand name.
What you’ll see on the shelf
- Unisom SleepTabs — typically doxylamine succinate 25 mg per tablet
- Store-brand “doxylamine succinate” nighttime sleep-aid tablets
- Some other night products may use doxylamine — read the label; don’t assume from packaging color
Cautions (same family of risks as other sedating antihistamines)
- Next-day drowsiness; don’t drive if not fully alert
- Extra caution in older adults (anticholinergic burden)
- Don’t mix with alcohol, other sleep aids, or sedatives
- Labels often warn about breathing problems, glaucoma, enlarged prostate
- If sleeplessness continues more than about two weeks, labels say stop and ask a doctor
- Chronic insomnia → clinician; CBT-I is first-line in sleep medicine guidance — this page is not a chronic treatment plan
