Detailed Answer:
Hi,
From the details that you have provided, it appears that your daughter has OCD as I mentioned earlier, which responded to
fluoxetine but was followed by antidepressant (fluoxetine) induced mania or
hypomania.
She will need an antidepressant like fluoxetine to control the obsessional thoughts but at the same time she will also need another medicine to prevent fluoxetine induced mania. The best medicines for this are mood stabilizers like lithium and
valproate, but in my opinion, considering her young age and the mildness of symptoms, we can try lighter medicines first. I have assumed that the excessive cheerfulness that she showed was mild and there was no major abnormality in the behavior. On the basis of this, I suggest that she should be given
Risperidone (Sizodon) 0.5 mg at night along with Fluoxetine (Flunil/Prodep) 10 mg in the morning.
I am suggesting a lower dose of fluoxetine this time, hoping that she will respond to this dose also and the lower dose will prevent a switch to mania that occurred at the dose of 20 mg per day. But if her exams are very near and the obsessive thoughts interfering very much with her studies, then she should start 20 mg as last time. You also need to keep in mind that fluoxetine takes a few weeks to start working.
The dose of risperidone is also the lowest possible to prevent any adverse effects. If this dose is sufficient to prevent a switch to mania, it is well and good. But if you notice any increase in cheerfulness and talkativeness like last time, this dose will have to be increased or some other medicine started. In my opinion, we should wait for the situation to arise rather than starting her on a high dose from now itself. But you will need to be very watchful and observant for any changes in behavior, so that the situation is not allowed to go out of control. Risperidone may cause some
stiffness in the body but that is usually seen at higher dosages. If, however, she experiences this side effect, then risperidone will have to be changed to some other medicine.
Propranolol will just lessen her anxiety a bit but will have no effect on her thoughts. She can also continue with the iron tablet but it is liable to cause
constipation.
I have suggested the mildest treatment possible for her. It is possible that some dose hike or other changes may be needed. If required, you can contact me directly at
