Most coughs come from a cold, flu, or another viral infection and clear up on their own within a few weeks (the NHS notes a cough usually settles within about 3 to 4 weeks), so the goal is usually self-care and symptom relief — rest, fluids, and honey help, and over-the-counter cough medicines can make you cough less but won't cure the cough. The right product depends on whether your cough is dry (suppressant) or chesty/productive with mucus (expectorant).
Available without a prescription — follow each label.
dextromethorphan Robitussin DM, Delsym Cough suppressant (antitussive) | Best for a dry, hacking cough that disrupts sleep or rest. It quiets the cough reflex. Coughing is a protective reflex that helps keep your throat and airways clear, so it is generally best to suppress a cough only when it is keeping you from sleeping or causing a lot of discomfort. |
Mucinex, Robitussin Expectorant | Best for a chesty, productive cough. It is intended to thin and loosen mucus in the airways so it is easier to cough up and clear. Drink plenty of fluids alongside it. |
honey Soothing demulcent (home remedy) | A simple, evidence-supported soother for cough and sore throat, taken on its own or in a hot lemon-and-honey drink. NEVER give honey to a baby under 1 year old, because of the risk of infant botulism. |
Tylenol Pain reliever / fever reducer | Does not treat the cough itself but eases the aches, sore throat, and fever that often come with a cold or flu. Do not combine with multi-symptom cold products that also contain acetaminophen — many cold and cough products share ingredients, and doubling up risks a dangerous overdose. |
A doctor may prescribe these — not for self-treatment.
Tessalon Perles Non-opioid antitussive (cough suppressant) | A doctor may prescribe benzonatate for a persistent, troublesome cough (it is prescription-only in the US, approved for ages 10 and older). It numbs stretch receptors in the airways to reduce the cough reflex. Capsules must be swallowed whole, never broken, sucked, or chewed (this can numb the mouth and throat and cause choking); overdose can be rapid and fatal, especially in children, so it must be stored in a child-proof container out of their reach. |
codeine or hydrocodone cough syrup Opioid cough suppressant (prescription) | A doctor may, in select cases, prescribe an opioid-containing cough medicine. The FDA limits these prescription opioid cough products to adults 18 and older because of serious risks (slowed or difficult breathing, misuse, abuse, addiction, and overdose). These are controlled prescription drugs — never take or share them on your own. |
albuterol inhaler Ventolin, ProAir Short-acting bronchodilator | If a cough is driven by asthma or wheezing rather than a simple cold, a clinician may prescribe an inhaler to open the airways. A new cough with wheeze or breathlessness should be evaluated by a clinician rather than self-treated with a cough syrup. |
antibiotics Antibacterial (prescription) | Most coughs are viral, and antibiotics do not help — the NHS is explicit that antibiotics only work for a bacterial infection, not a cold. A doctor may prescribe them only when they diagnose a bacterial cause such as pneumonia or whooping cough. |
Match the medicine to the cough. For a dry, tickly cough that won't let you sleep, a suppressant like dextromethorphan helps you cough less; for a chesty cough with phlegm, an expectorant like guaifenesin is meant to loosen the mucus so you can clear it. For nearly everyone, honey (only for those over 1 year), fluids, rest, and steam from a shower are a reasonable first step, with acetaminophen or ibuprofen for the accompanying aches and fever. A crucial safety point: many cold-and-cough products are combinations containing several ingredients at once, so read every label and never stack two products that share an ingredient (especially acetaminophen) or you can accidentally overdose. For children, follow strict age rules — the FDA cautions against giving over-the-counter cough and cold products to young children, and says children under 2 should not be given these products without a health care provider's advice because of serious, even fatal, side effects; many experts and manufacturers extend that caution to under 4. Instead, use a cool-mist humidifier, saline nose drops, fluids, and honey only if the child is over 1.
Get an urgent appointment or call a nurse line (in the UK, NHS 111) if your cough is severe or quickly getting worse, you feel very unwell, you have chest pain, the side of your neck feels swollen and painful, you are short of breath or finding it hard to breathe, or you are coughing up blood. See a clinician non-urgently for a cough lasting more than 3 weeks, a cough with unexplained weight loss, or any cough if you have a weakened immune system or a chronic lung condition. Seek emergency care immediately for serious trouble breathing, blue or gray lips or face, or chest pain with breathlessness. Babies, very young children, older adults, and pregnant people should have a doctor weigh in sooner rather than later.
General reference, not medical advice, and not a substitute for your doctor or pharmacist. The right choice depends on your symptoms, health conditions, age, and other medicines — always read each label and confirm before taking anything.
| An alternative to acetaminophen for the aches and fever accompanying a cough. Take with food; not suitable for everyone (e.g. stomach ulcers, certain kidney or heart conditions) — ask a pharmacist if unsure. |
diphenhydramine Benadryl Antihistamine (sedating) | For a cold-related cough that comes with a runny nose and sneezing, a sedating antihistamine may help dry secretions and ease the cough. It causes drowsiness, so it is best used at night. Avoid stacking it with multi-symptom products that already contain an antihistamine. |
