Chat with GP about Mounjaro

Told my GP about my Mounjaro journey today. He’s very supportive of it and praises its effects.

He told me he’s on it himself as well, lost 10kg so far, and is using a 15mg pen for 3.75mg doses (15 clicks), meaning he uses the pen for longer than 30 days.

Have I been a sucker sticking to 10mg pens for months for 10mg doses? Now that I’m weaning down to 7.5mg, should I get 12.5mg then 15mg pens to taper down my doses and save money?

I’m also a doctor (not GP), and have been sticking to the product guidelines to avoid complications, but now starting to wonder if the guidance is mainly to prevent economical use of the higher dose pens.
