Q: Can certain medications make psoriasis worse?

A: A number of medications can make psoriasis worse. The blood pressure medicine propranolol (and related beta-blockers) and a medication used to treat bipolar disorder, lithium, are two medications most closely associated with worsening psoriasis. Other medications include hydroxychloroquine (an anti-malarial drug), indomethacin (a pain medication), and interferon.
