I'm sorry :( As dropsy is a symptom not a disease the treatment depends on what exactly is causing it. It could be bacterial or parasites. Some meds work on some strains and others on other strains. In all cases, the meds should go internal or be fed and epsom salts should be used to pull off fluids. Even with the best of intentions and the right meds it's not always curable.

dropsy had no known cure, it is rare for a betta to survive it, what i did was put him/her in a container, put a dark cloth to give no light, and keep him/her warm :( sorry to hear that though, i lost many of the cause of dropsy around 7 or more
and you must catch it early
