Father in law is an ex-gp and gas been on and off statins. They don't suit everyone, the side effects can be unacceptable, but there are many different sorts and the trick is to find one that works.
The NHS is in need of a major overhaul wrt costs though and over prescription for blame avoidance is endemic, as is sending for blood test, prescribing over the counter medicines to the 97% prescriptions which are free to the patient etc. So yep can beliveve that statins are over prescribed.
Water retention medicines have been the big life savers.
