For older people and frail people, the long-term benefit of medicines reduces and the potential for harm from adverse effects increases. When the benefit–risk balance changes in this way, medicine review and optimisation are important to simplify the therapeutic regimen, reduce inappropriate medicines and minimise risks. In this article, pharmacist prescriber Linda Bryant uses two case studies to illustrate important considerations during medicine reviews

it almost looks like you are peering over the edge of a collapsed volcanic crater
Prepare to be gobsmacked when you emerge from a 10-minute bush walk to find yourself at the top of the Wairēinga/Bridal Veil Falls near Raglan.
As someone who has driven up and down this country many times, scouring the guidebooks for hidden treasures in the nooks and crannies of our awesome geography, I hadn’t even come across a photo of this spectacular sight, which made it even more impressive on first viewing.
A track follows alongside the Pakoka River to a clearing in the bush, where it disappears over a drop.
At first sight, it almost looks like you are peering over the edge of a collapsed volcanic crater, but actually the river has been flowing over the top of hard basalt rock, which has resisted erosion.
When the river comes to the end of the band of basalt, it falls down onto much softer sandstone. The resulting erosion has created a huge amphitheatre, with a striking classic waterfall, dropping 55 metres to the pool below.
The track to the top of the falls is wide and can be traversed by wheelchair. Beyond this point, a staircase with 261 steps leads to two further viewing platforms and bridge and shelter at the base of the falls.
It is about a 15-minute drive from Raglan to the start of the track.
