HPS Pharmacies wish to advise that Pfizer is experiencing a supply interruption for potassium chloride ampoules as follows:

Sterile Potassium Chloride Concentrate (Pfizer)
10 mmol (750 mg) of potassium chloride in 10 mL
ARTG 10793

Normal supplies are expected to resume in early October 2023.

Potassium Chloride (Juno) 10 mmol (750 mg) ampoules are currently available and may be used as an alternative. As concentrated potassium chloride ampoules are a high-risk medication, a risk assessment should be conducted prior to switching brands.

Key points to consider are:

  • Potassium chloride ampoules should only be stored in authorised clinical areas;
  • Ampoules should be stored in their original container until immediately before use; and
  • Ampoules must be physically separated from other ampoules of similar appearance.

Retain this notice in a prominent position, including in other related business units until supplies return to normal. Report any problems identified with medicines, vaccines or medical devices to the TGA.

Should you require further information regarding this matter, please contact Pfizer Australia on 1800 675 229 or your pharmacist at HPS Pharmacies.
