Same active ingredient — different manufacturer, form, price and FDA recall record. That last one is what our independent score measures.
Only one: Clarinex.

Imprint codes, colour and shape from the FDA’s labelling data. Match the imprint on your pill — or search any imprint.
Combination products containing desloratadine
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.
How long desloratadine keeps
No desloratadine label we read sets a separate limit for after opening, but they do specify how it must be stored — and the stability behind any date assumes those conditions.

From LactMed, the US National Library of Medicine’s Drugs and Lactation Database — quoted, not rewritten.
Full LactMed record for desloratadine: levels in milk, effects in breastfed infants, and the drugs it would consider insteadBecause of its expected low milk levels and lack of sedation and anticholinergic effects, maternal use of desloratadine is unlikely to affect a breastfed infant or milk production. Desloratadine might have a negative effect on lactation in combination with a sympathomimetic agent such as pseudoephedrine.

What people report to the FDA about desloratadine
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 8,999 reports naming desloratadine, and the FDA flagged 92% 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:
- fatigue519 reports
- pruritus464 reports
- dyspnoea435 reports
- nausea433 reports
- urticaria387 reports
- diarrhoea385 reports
- headache384 reports
- rash359 reports
Read these as a signal, not a rate. A report does not mean desloratadine 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 section above.

Frequently asked questions
Can you take desloratadine 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 desloratadine against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.
What forms does desloratadine come in?
Across the brands we track, desloratadine is currently marketed as tablet, 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 desloratadine?
We do not currently list a generic-labelled desloratadine product. That does not always mean none exists — it means none appears under a generic name in the FDA data we track. Ask your pharmacist.
