Drug Availability


HPS Pharmacies wish to give notice that Aspen Pharmacare Australia are currently experiencing an interruption to the supply of:

Timentin® Powder for Injection
Ticarcillin 3g/clavulanic acid 0.1g
ARTG 11165

The supply interruption is due to a shortage of the active ingredient. Normal supplies are not expected to resume until 2017.

Piperacillin is the only other penicillin with activity against Pseudomonas aeruginosa. Piperacillin, when used in combination with the beta-lactamase enzyme inhibitor tazobactam, offers a similar spectrum of activity.

In concordance with antimicrobial stewardship recommendations, prescribers are advised to consult the Therapeutic Guidelines: Antibiotic for an appropriate alternative.

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 your pharmacist at HPS Pharmacies, or Aspen Pharmacare Australia on (02) 8436 8300.

Information regarding expected dates for supply may vary subject to delays which are out of our control. HPS Pharmacies does not accept responsibility for such changes but will endeavour to keep our clients updated as information is made available from drug manufacturers or wholesalers.
