A cough helps clear your airways—but when it steals your sleep, relief becomes a priority. Unfortunately, evidence for many over-the-counter cough remedies is limited, and none cures a common cold. (cdc.gov) The cause matters: lingering coughs can come from allergies, postnasal drip, asthma, acid reflux, or certain blood-pressure medicines. Treating the cause may help more than buying another bottle. If you suspect a medication, ask your clinician about alternatives rather than stopping it yourself.
For a routine cold-related cough, start with rest, fluids, and honey, which may soothe coughing in adults and children at least one year old. Never give honey to an infant. (cdc.gov) Before choosing medicine, ask a pharmacist to check for interactions and duplicate ingredients. Decongestants deserve particular caution if you have high blood pressure or heart disease. (nhs.uk) See your clinician if a cough lasts longer than three weeks; seek urgent care for breathing difficulty, chest pain, or coughing blood. (nhs.uk) Your cough may need attention— but your wallet doesn’t need to catch a cold, too.
