If you have noticed this  weight gain happening post taking the medicines , then it could be a side effect. Need to understand your body condition and  other past mental history to recommend a suitable solution. However as  you are aware, medicines are just one part of any psychic treatments as it just control your neurotransmitters. In parallel you need to  adopt certain lifestyle changes , excersise, self therapies, counseling session, dietary etc to see a improvement. In your case thyroid is also a concern. Sometimes, natural body type, lifestyle, digestion issue , depression also play a role. So there are various factors influencing the body weight.
