Hello, Thanks for choosing health care magic for posting your query. I have gone through your question in detail and I can understand what you are going through. olimelt 2.5 mg and sertraline 25 mg will not help her with OCD. The treatment of OCd essentially requires the medications in high dosages. Lower dosage wont help. OCD is a very common illness and effects many. It can be mild and some times unrecognizable and sometimes it can be severe. You certainly need to be treated for OCD. Although there are plenty of options available like clonil, fluoxetine, escitalopram, fluvoxamine, sertraline etc all in high dosage my best option for my patients is fluoxetine in higher dosages. If at all sertraline is used , it has to be used above 200mg. Also there is an option of cognitive behavioural therapy. This therapy is taken by either a psychologist or a psychiatrist in which the therapist identifies impaired cognitions (Thoughts) and try to correct them. They are 15-20 min weekly session and there should be around 8-10 sessions to help you with your illness. Hope I am able to answer your concerns. If you have any further query, I would be glad to help you.
