Yes it’s common. Look for uncritical articles about a specific drug, always always always look at people’s affiliations - all interests should be listed in papers. If you’re unsure go into PubMed and look at their other papers and google them. ‘Cast of thousands’ author lists are a giveaway too in biological fields (and totally normal in physics.)
So off label usage isn’t always bad. It can and does save lives, but it’s something that shouldn’t be done lightly and is a big responsibility. By label, we mean the indications that the drug is tested and approved for by the relevant body (FDA in America, MHRA in the Uk.) to get approval for an indication you must conduct trials and present the data to the body and they must approve it.
Pharma companies CANNOT MARKET for indications that are off label. Less of a problem in the UK because you can’t market direct to patient here but huge in the US and where you can.
A prescribing doctor retains responsibility for their prescriptions.
Lots of off label use is legit. For example, if you’re dying and there’s a promising but I tested cancer drug that might give you a few extra months. Or it’s just that the drug has never specifically been tested in kids or pregnancy women (most of the drugs for hyperemesis have never been tested in pregnant women, but they have long useage records with good safety.)
In some cases it’s that the drug has been around forever like aspirin and it’s used for all sorts of stuff without any trials ever being done.
Or things like antidepressants used for anxiety or as mild antipsychotics. That sort of stuff.
The legal stuff is fuzzy. The FDA don’t regulate what the drugs are used for atcthe doctor level - they only say what they have been approved for and can be marketed for. And there has to be a presumption that. Doctors are NOT compelled legally to tell the patient that the use is off label but they can be held responsible for what they prescribe.
That’s the level my knowledge of the legalities stops I’m afraid - it’s a balance between the responsibility of the medic to treat and their responsibility to be ethical.
Where pharma companies push doctors or even provide incentives to get them to prescribe you have an ethics breach. Where they are pushing to prescribe for off label use that breach is even more serious because it creates direct conflict between the interests of the patient and that of the company.
Incidentally, let me see if I can find the ruling... a little drug called Lupron was in 2001 involved in such a case (kickbacks mainly) which was the biggest ever at the time. Scroll down to TAP/Lupron here:

Yes I’m on the sofa and feeling frankly a bit horrid :) thinking of serving an eviction notice on the little bugger ...
