Yes, it often takes longer for the rest of the pellet to dissolve up to several weeks. Sometimes the implant disappears before the preset time. Many factors can influence this: inflammation, violation of fibrous capsule formation around the implant in the subcutaneous tissues, of the implant site, accelerated metabolization of the biodegredible polymer enzyme systems of the patient, splitting into small fragments, pellets, increased friction surrounding tissue due to the strong muscle contractions and etc.
Some patients start fighting the implant, some even confessed trying to heat it up with hair dryer, or to melt it with hottie. Others reported crushing the implant in their body. The smart ones have just asked a surgeon to remove it. None know the truth about this, but we can help once again should a patient becomes responsible and corrects their strategy by returning to the Naltrexone maintenance.
