The drug you used Risperdal contains Risperidone an atypical antipsychotics and it has an effect on libido, but it will wear off when you stop taking medicine.

Religious constraints. 6. Long term illness. 7. Negative attitude towards your partner. 8. Hormonal issue. 9. Diabetes and hypertension. These are other issues causing low libido. If you can share details regarding the above reason, we can work on your cause.
