How much can medications help OCD?
This varies by individual but generally a 30% decrease in symptoms can be expected. The medications may take from six to twelve weeks to start showing an effect. The initial mechanism of these medications is to increase the availability of the neurotransmitter serotonin at the synapses (connections between brain cells) in the brain. This leads to other brain changes over several weeks which may be more related to improvement in OCD symptoms.
