The Various Causes Of Psoriatic Arthritis

Certain Medications

Certain medications are also linked with triggering psoriatic arthritis. Lithium, which is commonly used to treat a plethora of psychiatric disorders (such as manic depression), aggravates these arthritic symptoms in nearly half of the psoriasis patients who take it. Antimalarials, which are recommended to only be taken for short periods, may also cause these symptoms to flare up. However, the effect is rarely immediate, presenting typically two to three weeks after the medication is taken. Certain heart medications, like quinidine, has been reported to worsen psoriasis, as have some high blood pressure medicines. The nonsteroidal anti-inflammatory drug indomethacin has worsened some cases of psoriasis, but other anti-inflammatory medications can typically be substituted in to reduce side effects.
