These five are the most reliable options for sleeping through a cough.

What to look for
cough suppressant
(dextromethorphan, often abbreviated DM) and a **sedating antihistamine** (doxylamine or diphenhydramine). Any formula with both those two actives will help you sleep through coughing. The rest of the formula. decongestant, fever reducer, expectorant. depends on your specific symptom load. Avoid stimulating decongestants like pseudoephedrine in nighttime formulas, as they can counteract the sedative effect.

FAQs
Most nighttime cough formulas use doxylamine succinate or diphenhydramine. both are sedating antihistamines that cause drowsiness while also reducing cough sensitivity. They are paired with dextromethorphan to suppress the cough reflex directly. Together they make it easier to fall asleep and stay asleep despite respiratory irritation.
Nighttime cough medicines with sedating antihistamines are generally intended for short-term use of 7 days or fewer. Extended regular use can lead to tolerance, next-day grogginess, and dependency on the sleep aid component. If you need sleep support for coughing longer than a week, speak to a doctor about the underlying cause rather than relying on OTC night formulas.
No. Sedating antihistamines like doxylamine and diphenhydramine can cause grogginess that persists for 6 to 8 hours after the dose. If you need to drive or operate machinery early in the morning, either take the dose very early in the evening or switch to a non-sedating daytime formula. Always allow a full 8 hours before driving after any sedating medication.
