I have OCD and was a prescribed a low-dose of Lamictal (100mg) which has been working wonders. However, just recently my pharmacy switched to an new manufacturer for Lamictal under Unichem, and I have noticed that my anxiety and intrusive thoughts have been unmanageable since switching over. Is this a possible side effect? I know that just the slightest change in dosage can set it off badly, so that’s why I’m worrying.

Thank you.
