Retatrutide when Zepbound stops working
I started tirzepatide OVER 3 years ago, and lost weight on it very rapidly (290 down to 190 at my low -- about 15 lbs over my ideal weight, and the lowest I've weighed in 40 years). I titrated up to the max dose pretty quickly. But after about 1.5 years weight started creeping back up... slowly. Now I'm up to nearly 230. Yikes! Not horrible, but the trend is in the wrong direction.
This is a disappointment, but not a shock. It's story with many drugs, and in particular weight loss drugs -- after awhile, they work less well in some cases (some people seem to do fine on a low or intermittent dose).
So, what to do?
-- stop, and hope it's more effective if I return after a break. This risks major weight gain.
-- adjunctive therapy -- ADD something. Possibilities: Phentermine, Topamax, Cagrilinitude...
-- switch to something else.
Has anyone tried switching to Retatrutide when Zepbound becomes less effective? Did you wait a week or more after the last Zepbound dose, then start Retatrutide at the lowest starting dose for that drug? I do not know of any investigations along such lines, since Retatrutide is not yet on the market (and may never be approved for it)
