Colchicine: ongoing caution needed

In the latest edition of Prescriber Update, Medsafe reminds clinicians about the risks associated with colchicine. Between 2016 and January, 2021, 56 colchicine poisoning incidents were reported to the National Poisons Centre. Reasons for the incidents included young children finding and taking the medicine, errors in dosing (it is not stated whether the medicine was prescribed in error or the patients took the medicine inappropriately) and intentional overdose. Prescribers are reminded that colchicine has a narrow therapeutic index and that there is no effective treatment for colchicine poisoning.

N.B. We are currently updating our two-part series on gout, including information on colchicine dosing – watch this space, and a gout topic is also available in our Primary Care Update Series.

Nitrofurantoin prescribing

The June edition of Prescriber Update includes a reminder about prescribing nitrofurantoin by brand. We also highlighted this issue in Bulletin 20. Most clinicians prescribe generically but to avoid confusion and minimise prescribing errors it is safer for some medicines to be prescribed by brand. There are now two funded formulations of nitrofurantoin: 50 and 100 mg immediate release tablets (Nifuran) and 100 mg modified release capsules (Macrobid). A regimen of 100 mg nitrofurantoin modified release, twice daily, is indicated for the treatment of acute uncomplicated urinary tract infection and is likely to improve treatment adherence.

NZF updates for June

New sections added to the NZF in the June, 2021, release include:

No new patients to be prescribed oxybutynin: liquid to be discontinued

Oxybutynin is indicated for the treatment of urinary frequency, urgency and incontinence. Due to the supplier of oxybutynin in New Zealand (Apotex) withdrawing from the market, this medicine is now in short supply and no suitable alternatives have been able to be sourced. As of 1 June, only patients previously prescribed oxybutynin tablets or liquid can receive a new prescription (pharmacists can endorse the prescription). It is anticipated that stock of oxybutynin oral liquid will run out by October, 2021, after which it will be discontinued. PHARMAC is still seeking an alternative supply of 5 mg tablets, but tablets may also need to be discontinued in the future. PHARMAC has received clinical advice that solifenacin may be a suitable alternative for some patients.

Opportunity to participate in research on mental health in ethnic Chinese patients

[Human Ethics Committee Reference Number: D21/174]

We are undertaking a research project around the experiences of ethnic Chinese patients who have accessed mental health therapy in New Zealand. As a primary healthcare provider and first port of call for many patients seeking help, we would appreciate your insight into this topic. We would like to invite you to participate in a 13-question survey regarding your experience around mental health consultations with ethnic Chinese patients. The survey takes around 5 minutes to complete. As a token of gratitude, we will distribute the results of this project to all participants of this survey, as soon as they are available (expected to be in the first half of 2022).

With thanks,
Denzel Chung, Student Researcher and Dr Katherine Hall, Senior Lecturer

Paper of the week: The news is not good for drinkers

Emerging evidence from two different studies has cast further doubt on what constitutes a safe level of alcohol consumption. In the first study, the authors analysed data from the UK Biobank, which includes neuroimaging results and clinical data from over 40,000 people. They found that alcohol consumption had a negative linear association with global brain grey matter volume and widespread negative associations with white matter microstructure. Higher blood pressure and body mass index and binge-drinking increased the risk of alcohol-related harm to the brain. However, no safe level of alcohol consumption was found in terms of adverse effects to the brain structure.

In the second study, presented at the American College of Cardiology 2021 Scientific Session, the authors found that as little as one alcoholic drink in a person with atrial fibrillation (AF) doubled the risk of an episode of AF occurring within the following three to four hours. The greater the volume of alcohol consumed, the higher the risk.

Given the growing bank of evidence of association between alcohol consumption and detrimental effects on cardiovascular health, liver and other major organs, and association with several different types of cancer, it may just be time to call the last round. At the least, we should be consuming alcohol sparingly, rather than considering the current recommendations for upper limits of alcohol intake as a target to meet. There is no such thing as no-risk drinking, but low-risk drinking aims to balance the risk of negative health outcomes with the benefits of socially acceptable levels of consumption that many people enjoy.
