The Pharmacist’s Take By · Clinical pharmacist · Written

Dextromethorphan, the “DM” on many cough syrups, is a familiar over-the-counter cough suppressant that calms the brain’s cough reflex, meant for short-term relief of cough from a cold or inhaled irritants; it has been on the market since about 1957 and is widely available as a generic. Most people tolerate it well, though nighttime formulas can cause marked drowsiness and children may become excitable. Never take it with an MAOI (certain drugs for depression, psychiatric conditions or Parkinson’s disease) or within 2 weeks of stopping one. See a doctor if the cough lasts more than 7 days, comes back, or brings fever, rash or a lasting headache.

Clinical pearls

  • Many multi-symptom cold and flu products already contain dextromethorphan, so read every label before stacking two cough or cold medicines.
  • Dosing differs by product (Delsym-type suspensions run about every 12 hours), so shake well and use only that product’s dosing cup.
  • Delsym-type 12-hour suspensions are labeled not for children under 4, and every product belongs out of children’s reach.
  • Nighttime versions can cause marked drowsiness, so skip alcohol and check before combining them with sedatives or tranquilizers.

What Dextromethorphan is used for

▾

Dextromethorphan is used for short-term cough relief. Uses vary by product.

  • Temporarily relieves cough from minor throat and bronchial irritation, as with the common cold or inhaled irritants (many oral liquid, suspension and tablet products).
  • Reduces the urge to cough to help you get to sleep (for example, Delsym products and Delsym Cough tablets).
  • Helps reduce the intensity of coughing (for example, Mucinex Instasoothe lozenge and Giltuss DM).
  • Helps loosen phlegm (mucus) and thin bronchial secretions (for example, Honey Works syrup, Premier Value Tussin Cough and CVS Long Acting Cough).

Dextromethorphan dosage

▾

Dextromethorphan is mostly taken by mouth. Dosing depends on the product and the person's age.

  • Extended-release suspensions such as Delsym: shake well, measure with the cup provided, and dose every 12 hours. Not for children under 4.
  • Giltuss Honey DM Cough: dosed every 6 to 8 hours, no more than 4 doses in 24 hours. Consult a doctor for children under 4.
  • Don't use a dosing cup from another product.

Follow the directions on your product or from your prescriber or pharmacist.

Dextromethorphan: pharmacist answers to common questions

Quick, plain-English answers to the questions patients ask most about Dextromethorphan — the kind of thing our pharmacy team would talk through with you at the counter.

What is this medicine for?

▾
It's a cough suppressant. It temporarily relieves cough from minor throat and bronchial irritation, like with a cold or inhaled irritants. Some products also help you sleep by calming the urge to cough.

How often can I take it?

▾
It depends on the product. Extended-release suspensions like Delsym are labeled for every 12 hours, while Giltuss Honey DM Cough is every 6 to 8 hours with a 4-dose daily limit. Check your label and use the dosing cup that came with it.

Can I take it with my antidepressant?

▾
Be careful. Don't use it if you take a prescription MAOI, or within 2 weeks of stopping one. If you're not sure whether your medicine is an MAOI, ask me or your doctor before taking it.

What side effects should I expect?

▾
Nighttime products can cause marked drowsiness, and children may become excitable. Avoid alcohol and be careful driving.

When should I see a doctor about my cough?

▾
See a doctor if the cough lasts more than 7 days, comes back, or comes with fever, rash or a headache that lasts. Also check first if you have a chronic cough from smoking, asthma or emphysema, or a lot of phlegm.

Is it safe in pregnancy or for kids?

▾
If you're pregnant or breastfeeding, ask a health professional first. For children, some products aren't for kids under 4, so follow the age directions on the label.

Is Dextromethorphan available over the counter?

▾
Yes. The Dextromethorphan products listed with the FDA are sold over the counter, without a prescription (the oral suspension, oral solution, extended-release oral suspension, capsule, tablet and lozenge forms). Follow the package directions. Your pharmacist can tell you which product is right for you.

When was Dextromethorphan first available?

▾
The earliest FDA record we hold for Dextromethorphan is from 1982: its first approval in Drugs@FDA or its earliest product listing in the NDC Directory, whichever is older. Many older medicines were in use before their first formal FDA approval, so this is the earliest date on record, not necessarily when Dextromethorphan was first used.

Who makes Dextromethorphan?

▾
64 companies currently list Dextromethorphan products in the FDA's NDC Directory, including Haleon US Holdings LLC, Reckitt Benckiser LLC, Amazon.com Services LLC. That count includes repackagers and distributors as well as manufacturers (companies that sell only the raw ingredient are not counted), so fewer companies actually make it; the label on your bottle names the one that supplied yours.

How widely Dextromethorphan is used (Medicaid data)

A general measure of how commonly Dextromethorphan is prescribed, based on Medicaid — one of the largest public drug programs. The figure below is prescriptions filled in Q1–Q4 2025, summed across every form and brand of the drug.

Think of this as a proxy for how widely Dextromethorphan is used, drawn from freely available public data. Medicaid is just one program — these numbers don’t include Medicare, other government coverage, or commercial and cash-pay prescriptions, so real-world use is higher than what’s shown here.

Shares are of the Medicaid prescriptions shown here. Product grouping follows RxNorm (the National Library of Medicine’s drug terminology), so “one product” means one strength & dosage form regardless of manufacturer. Dollar figures are gross Medicaid reimbursement before mandatory rebates — rebates (often large, especially for brand-name drugs) are confidential, so actual net cost to Medicaid is lower than shown.

A general popularity signal; it excludes Medicare, commercial insurance and cash prescriptions, so it is not total U.S. use.
