Hello there. It would be better not to give both Fluoxetine and Escitalopram together. You could discuss with your neurosurgeon about your mother being already on fluoxetine and he could give you an alternate suggestion. Alternatively a psychiatrist can be consulted for both fibromyalgia as well as insomnia and they can prescribe medications for both these conditions.
Next Steps
Kindly discuss with your doctor about the prescription. Alternatively consult a psychiatrist for both conditions.
Health Tips
Better to avoid adjusting clonazepam on your own as it can lead to addiction if not used under the guidance of an experienced doctor
