A number of medications can exacerbate psoriasis; therefore, avoidance of these agents may help to prevent or minimize flare-ups. Lithium and withdrawal from systemic corticosteroids are well known to cause disease flare-ups.
Other drugs that have been implicated include beta-blockers, antimalarials (although, as previously mentioned, evidence suggests that hydroxychloroquine does not exacerbate skin lesions), and NSAIDs. If skin lesions worsen with an NSAID, switch to a different family of NSAID.
Prevention includes rest and exercise. Joint protection, including splints, braces, and other supports, may be helpful. No definitive prevention exists because this is a chronic disease that can wax and wane.
