Combination products containing chlorpheniramine
A combination is a different drug — different dosing, different warnings. It is listed here so you can find it, not so you can substitute it.
Chlorpheniramine recalls
From the FDA Enforcement database. A recall covers specific lots — not the drug as a whole.
Chlorpheniramine and breastfeeding
From LactMed, the US National Library of Medicine’s Drugs and Lactation Database — quoted, not rewritten.
Full LactMed record for chlorpheniramine: levels in milk, effects in breastfed infants, and the drugs it would consider insteadSmall (2 to 4 mg), occasional doses of chlorpheniramine are acceptable during breastfeeding. Larger doses or more prolonged use might cause effects in the infant or decrease the milk supply, particularly in combination with a sympathomimetic such as pseudoephedrine or before lactation is well established. Single bedtime doses after the last feeding of the day may be adequate for many women and will minimize any effects of the drug. The nonsedating antihistamines are preferred alternatives, though.
National Institute of Child Health and Human Development, record revised April 15, 2026. LactMed states its information is not a substitute for professional judgement.
What people report to the FDA about chlorpheniramine
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 6,815 reports naming chlorpheniramine, and the FDA flagged 91% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:
- nausea640 reports
- diarrhoea559 reports
- dyspnoea470 reports
- fatigue465 reports
- pyrexia454 reports
- vomiting447 reports
- pneumonia319 reports
- neutropenia304 reports
Read these as a signal, not a rate. A report does not mean chlorpheniramine caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label.

Frequently asked questions
Can you take chlorpheniramine with other medicines?
It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run chlorpheniramine against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.
What brand names is chlorpheniramine sold under?
We track 3 chlorpheniramine-containing products in the U.S.: Teldrin, Chlorpheniramine Maleate and Chlor-Trimeton. They are the same active ingredient; they differ in form, manufacturer, price and FDA recall record.
What forms does chlorpheniramine come in?
Across the brands we track, chlorpheniramine is currently marketed as capsule, extended release, tablet, tablet, extended release and injectable, per the FDA's National Drug Code Directory. Each form is dosed differently — follow the label for the exact product you were prescribed.
Is there a generic chlorpheniramine?
Yes. Our catalog lists 1 generic chlorpheniramine product alongside the brand versions. A generic has the same active ingredient and must meet the FDA's bioequivalence standard; it usually costs less. Ask your pharmacist which one your plan covers.
Has chlorpheniramine been recalled?
The FDA's Enforcement database lists 1 recall record whose product description mentions chlorpheniramine. The most recent: Chlorpheniramine Maleate 4 mg tablets (Oct 21, 2024). A recall applies to specific lots, not to the drug as a whole — check the record for the affected lot numbers.
