PBS funds Botox to prevent migraines

The PBS has started funding Botox injections to prevent chronic migraines.

The prescription drug, which has various cosmetic and medicinal uses, is subsidised for adults who suffer headaches at least 15 days a month.

They must also have unsuccessfully tried at least three other preventive medications.

A specially trained neurologist gives patients injections into their head and neck every 12 weeks.

These are given with a fine needle in 31 spots, including the forehead, temples and back of the head, says Melbourne neurologist Dr Richard Stark.

Migraine symptoms include visual disturbances such as flashing lights and blind spots along with nausea and vomiting.

The condition can lead to depression and anxiety, largely because of missed work and loss of income.

However, only a small proportion of people with chronic migraines have been diagnosed, says Sydney neurologist Dr Con Yiannikas.

People experiencing multiple headaches a month should ask their GP to refer them to a neurologist to explore preventative treatment options, he says.

The PBS also funds Botox for conditions including cerebral palsy, urinary incontinence and excessive sweating.
