I guess the price varies depending on the dose but the box I have in front of me costs 14.70chf for a hundred 75ug tablets so a whole year’s supply would be under 60chf.
It doesn’t seem worth opting for a lower franchise and higher premiums just for that but it might be worth it if you need specialist visits and other tests associated with it throughout the year.

The insurance company won’t reimburse any if the costs until your franchise is reached and you wouldn’t even reach the lowest franchise possible (300chf) just for the tablets. It’s the consultation costs which will be the biggest expense for you.
