Prompt to update BNF App on iOS

We are aware that the BNF app on iOS is currently alerting all users to update their app, via a pop-up which states:

“Update available: A new version of this App is available which contains the latest BNF and BNFC content. Please update to the latest version”.

This is occurring for all users, irrespective of whether they are using the most up-to-date version.

If your app indicates that you are using version 2.1.21, and the October 2019 content update, then this is the most recent content and no update is required. You should choose “Later”, and the pop-up will disappear.

If your app indicates that you are using a version earlier than 2.1.21, or a content update dated earlier than October 2019, then you should update your app so that you are using the most up-to-date content. After updating, you may still be prompted to update again but you can choose “Later” so that the pop-up disappears.

We apologise for any inconvenience.

Celebrating 70 years of the BNF

70 years supporting you make effective decisions

Since 1949 the British National Formulary (BNF) has been the UK’s most trusted and authoritative healthcare resource, helping to ensure the safe and effective use of medicines at the point of care.

Over the past 70 years we’ve never lost sight of what’s important, and looking ahead we will continue to provide unrivalled guidance on prescribing, dispensing and administering medicines.

As part of our 70th celebration we want to share some behind-the-scenes detail about what makes the BNF special.

BNF Interactions

In 2017 the BNF interactions were rewritten to be more consistently structured, allowing users to find interactions more easily, and giving more information about the severity and evidence of an interaction. All interactions are listed under individual drugs. When checking interactions for combination drugs or co-drugs, it is essential to refer to each drug in the combination. The interactions section of the drug monograph clearly states the drugs (or drug classes) that need to be referred to in the interactions (Appendix 1 in print).

Co-trimoxazole

Please note that co-trimoxazole currently has its own entry in print that does not include the interactions for trimethoprim. As stated above, it is essential to refer to both drugs (trimethoprim and sulfamethoxazole, under sulfonamides) to find all relevant interactions for this drug. This inconsistency will be corrected in the upcoming September editions, BNF 78 and BNF for Children 2019-2020. Digital products including MedicinesComplete and the BNF app have been corrected for the June monthly update.

For information on how to use the BNF, see How to use BNF publications. For more information on how to use the interactions content, see Appendix 1 Interactions.

Important notice to users of the iOS and Android BNF and BNFC Apps

Please ensure that you update your BNF app before you access the content. A fix has been made to correct a technical error that was resulting in some content not appearing. Online web versions of the BNF are unaffected.

The correct version to run for the December 2018 monthly update is 2.1.8 (iOS) and 2.1.11 (Android).

Please note that all digital platforms are updated every month. For the most up-to-date content and functionality, please ensure that you are using the latest version.

Clarification of the Doses at extremes of body-weight statement for vancomycin in BNF and BNF for Children

In July, BNF and BNF for Children digital products were updated in line with the SPC to recommend weight-based dosing of intravenous vancomycin. The ‘doses at extremes of body-weight’ section erroneously included a recommendation about dosing based on ideal body-weight. Note that the manufacturer recommends that intravenous weight-based doses for all patients should be based on total [actual] body-weight.

BNF and BNF for Children digital products will be updated to reflect this recommendation in both BNF and BNF for Children in the next scheduled update in mid-August.

Clarification of the parenteral dose of quinine for the treatment of malaria in BNF and BNF for Children

The maintenance dosing recommendations for parenteral quinine for the treatment of malaria have been updated in the BNF and BNF for Children digital publications. The requirement to reduce the maintenance dose to 5–7 mg/kg if parenteral treatment is needed for more than 48 hours has been added to all parenteral dose statements.

These updated recommendations will be present in the June monthly update for all digital products of BNF and BNF for Children; these changes will also be reflected in the print editions for BNF 76 and BNF for Children 2018-2019.

Clarification of dose of tramadol with paracetamol in BNF and BNF for Children

In light of a range of strengths now being available for combination tramadol-paracetamol preparations, the dose in BNF and BNF for Children has been updated in digital products.

The previous dose, expressed as tablets was not appropriate for the highest strength preparation (tramadol 75mg and paracetamol 650mg). The dosing has therefore been updated to express the dose in milligrams.

The new dosing has now been published in the tramadol with paracetamol monograph in digital versions of the BNF Publications.

Palliative care: tell us what you think

BNF Publications are always looking for ways to improve. Currently, we are particularly keen to understand what users think about the palliative care content within our publications.

With that in mind, below is a link to a short survey (approximately 10 minutes) that aims to help us understand how BNF Publications can further support palliative care practice. We thank you in advance for your participation.

Correction of dose of Ironorm® Drops in BNF for Children

The dose of Ironorm® Drops for the treatment of iron deficiency anaemia has been updated in the BNF for Children digital products.

The dose incorrectly stated a maximum volume per dose of 8mL, instead of a maximum volume per day of 8mL.

The correct dose is as follows:

Iron-deficiency anaemia (therapeutic)

By mouth

Child 1 month–5 years
0.12–0.24 mL/kilogram daily in 2–3 divided doses; maximum 8 mL per day.

Child 6–11 years
0.12–0.24 mL/kilogram daily in 2–3 divided doses; maximum 8 mL per day.

Child 12–17 years
4 mL 1–2 times a day.

This updated dose will be present in the October monthly update for all digital products of BNF for Children.
