New article: Cervical cancer - early detection and referral

In the first article of our gynaecological cancer series, supported by Te Aho o Te Kahu, Cancer Control Agency, we discuss the latest guidance on prevention, early detection and referral of patients for investigation for cervical cancer.

The risk of cervical cancer is significantly reduced through HPV vaccination and cervical screening programmes, however, there are still 168 new diagnoses and 53 deaths caused by cervical cancer on average each year in New Zealand. Upcoming changes to the cervical screening programme in New Zealand in 2023, including moving to HPV primary screening, are predicted to further reduce the burden of cervical cancer.

Accuretic stock to be withdrawn on 31 October, 2022

The supplier of Accuretic (quinapril + hydrochlorothiazide) has advised that all remaining stock will be withdrawn from distributors on 31 October, 2022. As first reported in Bulletin 53, patients taking Accuretic require a change in anti-hypertensive treatment due to contamination issues.

Prescribers can currently still claim for first consultation costs in relation to transitioning patients to an alternative medicine. The cost of follow-up consultations is not reimbursed. Accuretic will be delisted from the Pharmaceutical Schedule on 1 December, 2022.

Alternative brand of pregabalin to cover supply issue

Pharmac has been notified of a potential supply issue with Pregabalin Pfizer, in November 2022. Both the 25 mg and 75 mg capsules may be out of stock for a short period.

To minimise disruptions, Mipharm pregabalin 25 mg and 75 mg capsules will be funded from 1 November, 2022. Mipharm pregabalin is not approved for use in New Zealand by Medsafe and will need to be prescribed and supplied under Section 29. Patients should be advised the packaging and capsules will appear different.

Consultation to fund new medicines for inflammatory bowel disease

In Bulletin 59 it was reported that Pharmac was seeking feedback on a proposal to fund a new medicine for inflammatory bowel disease (IBD). There is now a proposal to fund another new medicine for IBD, ustekinumab (Stelara) and to extend funding of infliximab (Remicade) to people with IBD-associated arthritis. Submissions are due by 4 pm, Wednesday 26 October.


Do not prescribe vildagliptin and dulaglutide concurrently

There have been recent reports to the NZF of patients taking vildagliptin (alone or formulated with metformin) concurrently with dulaglutide. In some cases, patients have experienced adverse effects, although it is unknown if this was due to an individual medicine or the combination of treatment. Using these medicines concurrently is not recommended as they have a similar mechanism of action. Vildagliptin must be stopped before initiating dulaglutide.

Potential safety signal: gestational diabetes in association with quetiapine

Due to metabolic adverse effects, quetiapine and some other atypical antipsychotics can increase the risk of gestational diabetes if used during pregnancy. This issue was discussed at the most recent meeting of the Medicines Adverse Reactions Committee (MARC) in September, where it was recommended that the pregnancy section of the quetiapine data sheet should be updated to reflect this risk.

MARC also discussed the results from a 2018 study in New Zealand which suggested that quetiapine is widely prescribed for unapproved uses including sleep and anxiety, and use is increasing over time. This is a concern as prescribing quetiapine for an unapproved indication, without evidence of effectiveness and safety data, impacts the risk-benefit balance, particularly in pregnant women. Prescribers should take this into consideration when discussing treatment choices.

In response to this concern, bpacnz will publish an article on the metabolic adverse effects of atypical antipsychotics, including effects in pregnancy and discuss use of quetiapine for unapproved indications.


Reminder: be aware of medicine interactions with statins

We are reminding prescribers to be aware of medicine interactions when prescribing statins, particularly atorvastatin and simvastatin.

Statins can have serious interactions with some medicines, particularly potent CYP3A4 inhibitors such as macrolide antibiotics (e.g. erythromycin, clarithromycin), azole antifungals (e.g. itraconazole, ketoconazole) and ciclosporin, which can result in myopathy and/or rhabdomyolysis.

Check for medicine interactions prior to prescribing a statin to reduce the risk of adverse effects: https://www.nzf.org.nz/

Eating and drinking habits in New Zealand: report released

Manatū Hauora, The Ministry of Health, has published reports on the dietary habits of adults and children (aged 2 – 14 years) in New Zealand. The reports are based on information provided as part of the New Zealand Health Survey in 2018/19 and in 2019/20, therefore reflect eating habits prior to the COVID-19 pandemic.

The results were not unexpected; the eating habits of people in New Zealand often fall short of the Eating and Activity Guidelines for New Zealand Adults 2020. Consider any opportunity where you can incorporate healthier eating and lifestyle advice into interactions with patients, their caregivers and whānau.


Specialise as a GP webinars

The Royal New Zealand College of General Practitioners are running webinars to provide doctors interested in general practice an opportunity to find out further details on the profession and the General Practice Education Programme.

The next webinar will be held on Wednesday 9th November, from 6.30 – 7.30 pm: register here. The transcript from the session held earlier this week will be available online: register here to view.

Call for GP participants in sports-related concussion study

Researchers at AUT are investigating general practitioners’ knowledge and perceptions of return to play care following sports-related concussions. Identifying obstacles general practitioners are currently facing can guide future approaches to concussion care.

Participation involves a 60 – 90 minute in-person or online interview discussing your knowledge of return to play guidelines, considerations when managing patients recovering from concussion and thoughts regarding multi-disciplinary working relationships with physiotherapists. Researchers are especially interested to hear from general practitioners who identify as Māori or work in rural communities given the current healthcare workforce shortages and issues facing ngā kiritaki hauora Māori (Māori health consumers) in Aotearoa/New Zealand.

For further information about the study, contact Colin Hancock at colin@greatlakephysio.co.nz or Phone: 027 697 0466

Paper of the Week: Our wearable future

A recently published two-part Medscape series discusses the future of wearable technology for health monitoring. While most wearable technology has a long way to go before it becomes part of clinical practice, this series provides an interesting look into these possibilities.
