I'm on amitriptyline for migraines although I know it is predominantly used for an antidepressant (hence posting in this topic).
10mg no longer prevents my migraines so I now take 25mg. I used to be prescribed 84 x 10mg (so 3 months worth). Since starting 25mg I've been told by the doctor they're not 'allowed' to give me 3 months worth.
Apart from the cost, the inconvenience and the current Covid risk of getting a prescription filled every 2 months instead of 3 months, what I'm most frustrated by is not understanding why they aren't 'allowed' to give me 3 months of 25mg when they've happily given me 3 months of 10mg for a couple of years. Is it to do with the overdose risk? Because I'm taking them for migraines not depression I assume common sense would prevail.
