What’s the difference between citalopram and citalopram HBr?
“HBr” means hydrobromide. So “citalopram HBr” is citalopram supplied as the hydrobromide salt form, the way many brands and generics are labeled for prescription use. The active drug is citalopram either way; the salt form is about how it’s formulated and absorbed, not a different medication.
Are citalopram and citalopram HBr the same medicine?
Yes. They refer to the same active ingredient (citalopram), with “HBr” indicating the salt form (hydrobromide) used in the product labeling.
Does the “HBr” label change the dose someone should take?
In practice, prescribers and pharmacists dose by the amount of citalopram (the active ingredient), not by the salt name alone. Salt forms can affect the weight of the tablet, but dosing is standardized to the citalopram content. If you’re switching between products or formulations, follow the prescriber’s written dose and the pharmacy label.
Why do some labels say “citalopram” and others say “citalopram HBr”?
Product labeling often reflects the manufacturer’s naming conventions and the exact chemical form of the active ingredient (for example, “citalopram hydrobromide”). Both labels point to the same antidepressant.
Is there any clinical or side-effect difference between citalopram and citalopram HBr?
No meaningful side-effect differences are expected just from the HBr salt labeling, because the active drug is still citalopram. Differences that matter clinically are more likely due to the exact product (tablet strength, release formulation), dose, and patient factors than the “HBr” part of the name.
