Drug Availability

HPS Pharmacies wish to give notice that Clinect is experiencing a supply interruption for Imdur^® and Monodur^® as follows:

Imdur^® Durules
Isosorbide mononitrate 120mg
ARTG 62795 

Monodur^® Durules
Isosorbide mononitrate 120mg
ARTG 64284

Normal supplies of Imdur^® and Monodur^® 120mg tablets are expected to resume by 19 December 2022.

The Therapeutic Goods Administration (TGA) has made a Serious Scarcity Substitution Instrument (SSSI) to help manage this long-term out of stock situation. The SSSI allows pharmacists to substitute registered medicines containing 60mg of isosorbide mononitrate in a modified-release tablet while the 120mg tablets are unavailable.

This SSSI expires on 19 December 2022, unless revoked earlier by the TGA. Points to consider during this time include:

• The quantity supplied to a patient under the SSSI must match the total dose prescribed;
• The SSSI may not be used to substitute medicines if the prescriber has indicated on the prescription that substitution is not permitted; and
• The patient, or the person acting on their behalf, must consent to the substitution.

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 Clinect on (03) 9918 5555 or your pharmacist at HPS Pharmacies.
