Hi,
It can occur due to infection,
hormonal imbalance, cancer, psychological conditions, drug induced and several other causes. Considering his age, psychological morbidity and treatment following are possible causes which need to rule out in his case:
-Hot sleeping environment: Hope it is not in his case.
-Residual
anxiety and depression
-Hyperthyroidism: It is also associated with anxiety.
For evaluation get his serum T3/T4/
TSH done on empty stomach.
-Autonomic over-activity: common in anxiety and hyperthyroidism.
-Substance use like alcohol and heroine
Although
night sweats can occur with
Sertraline but in clinical population it is rare. It is better to rule out above condition first as a cause for night sweats.
Hope my answer was helpful. If you have further queries feel free to contact me again.
Wish you all the best.
