Male aged 59, 180cm, started at 104kg now 89 kg after 5 months of Saxenda. The Saxenda stopped working, I developed a tolerance, which is common. It happens with phentermine (Duromine) too, I have heard. Today I ordered 60 capsules of Duromine 30mg. I would have preferred to start on the 15mg dose because I react excessively to almost all medications, but I've read a lot of posts on other forums where people open Duromine capsules and take split doses, e.g. 15mg, and use that to titrate up to 30mg. Apparently it's okay to open the capsules because the phentermine is bound to a resin in the little balls inside that are slow release. The capsule dissolves away in the stomach anyway; it's just a vehicle to get the little balls through the mouth and esophagus without spilling. Anyone else opening capsules here?
