All four countries, side by side
| What we list | United States · FDA | United Kingdom · MHRA | Australia · TGA | Canada · Health Canada |
|---|---|---|---|---|
| Status | Not approved | Approved | Not approved | Not approved |
| Legal category | Not approved by the FDA | Licensed over the counter as a sore throat lozenge | Not registered | Not approved |
| Note | Ambroxol has never been approved in the United States, for cough or for anything else. | The licensed UK product is a 20 mg lozenge. The Parkinson trials used 525 to 1,260 mg a day, swallowed. That is a different dose, taken a different way, for a completely different purpose. | Not on the ARTG, Australia's register of medicines. | Not approved by Health Canada. |
| Agency | Check FDA directly | Check MHRA directly | Check TGA directly | Check Health Canada directly |
US FDA status: Not approved in the United States for any use. Widely sold over the counter in Europe, Asia and Latin America to loosen mucus. The Parkinson disease work is investigational everywhere, and it uses doses far above the ones used for mucus.. Reviewed Sep 2026.

The full Canada answerAmbroxol in sport and the military
Whether Ambroxol is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status. Before you compete or get tested, look up Ambroxol by name on the Prohibited List, or look up a named product in Global DRO. Under the World Anti-Doping Code, category S0 bans, at all times, any drug-like substance that meets two tests. No other section of the List covers it. And no government health regulator anywhere has a current approval for it as a treatment in people. Many substances that are approved somewhere are banned by name in another section. So approval does not mean a substance is allowed in sport.
