Cilazapril with hydrochlorothiazide: Discontinuation

Cilazapril with hydrochlorothiazide is a medicine used for the treatment of patients with hypertension who are not adequately controlled on monotherapy. This medicine may also be used for other indications.

What's changing?

Apotex, the supplier of cilazapril with hydrochlorothiazide has informed PHARMAC it will no longer be able to supply this medicine in New Zealand. The current supply is likely to run out by the end of 2020.

Apo-Cilazapril/Hydrochlorothiazide is the only Medsafe registered brand of cilazapril with hydrochlorothiazide tablets in New Zealand. This means cilazapril with hydrochlorothiazide will no longer be available to patients once the current supply runs out. New patient initiations will be restricted.

Please note that this discontinuation does not apply to cilazapril tablets without hydrochlorothiazide.

When will cilazapril with hydrochlorothiazide be unavailable?

  • From 1 March 2020, cilazapril with hydrochlorothiazide will no longer be funded for new patients.
  • From the end of 2020, current cilazapril with hydrochlorothiazide stocks are likely to run out.

From 1 March 2020, prescribers will need to endorse any prescriptions for cilazapril with hydrochlorothiazide for patients who were taking this medicine prior to 1 March 2020.

Pharmacists may annotate the prescription as endorsed where there exists a record of prior dispensing of cilazapril with hydrochlorothiazide.

People taking cilazapril with hydrochlorothiazide will need to talk to their health care professional about alternative treatments.

When changing patients to another fixed dose combination it is recommended to monitor blood pressure and renal function (creatinine and electrolytes).

A fixed dose combination would be the preferred alternative to cilazapril with hydrochlorothiazide, although some people may prefer to change to two separate medicines (i.e. an ACE inhibitor and a separate diuretic). Currently cilazapril is used infrequently or not at all in other countries and we are aware of only one manufacturer of the active ingredient internationally. For this reason, alternative treatment agents should be considered. There are a number of different funded ACE inhibitors and one of these could be prescribed together with a funded thiazide or thiazide-like diuretic.
