Medicine shortages

mercaptamine (cysteamine) bitartrate

Current shortage

The TGA records this medicine as being in shortage now. A shortage often affects some brands, strengths or pack sizes and not others, so a supply of the medicine may still be available. Your pharmacist can tell you what is in stock and what alternatives exist.

The TGA has assessed this shortage as critical impact. That is a judgement about how hard the medicine is to substitute in clinical care, not a prediction about any one person. If you take this medicine, speak to your pharmacist or doctor about what is available. Do not stop or change how you take it on your own.

1 product record on the Australian Register of Therapeutic Goods, listed in full below. The TGA last updated this information on 12 June 2026. Not medical advice.

The TGA does not publish a reason for a shortage, so Voxsanity cannot show one. Nothing on this page is an explanation of why supply is affected — that information is not in the source and is not inferred here.

This is national information. The TGA records shortages for Australia as a whole. There is no state, territory or pharmacy-level stock information in this data, and Voxsanity cannot tell you whether a particular pharmacy has a medicine in stock. Your pharmacist can.
