It’s fat soluble so the more body fat there is, the more it’s absorbed along the way and the efficacy drops, but you would probably benefit from talking to a provider/pharmacist about possibly having a larger dosage or looking into other options that may be more beneficial to you. The more detailed the discussion about your health, history with medication, etc., the better off you’ll be in finding options that are best for you!
I’m quite obese and know my medications have had to be adjusted as a result, but I’m not on BC (trans) so I can’t give definitive advice outside of what I read. But I do highly recommend meeting with a provider to discuss your options regardless! Always going to be more tailored to you than what you’d find from any of us.
