Paradoxical new-onset intrusive thoughts with beta blocker

Patient is female, mid-30s, pmh of single MDE treated to remission with SSRI, seen in a PCMHI context. Was prescribed the lowest possible dose of a beta blocker (propranolol) for borderline HTN and reported experiencing sudden, new-onset intrusive thoughts after starting it. I know BBs are often used to treat anxiety but have you ever heard of a paradoxical reaction where they cause it? Thanks!
