Patient reassurance is essential once the diagnosis is made. Phytophotodermatitis (PPD) is a self-limited problem that resolves with removal of the offending agent. Patients should avoid the offending agent (furocoumarin).
Cool wet compresses may be used for acute lesions. Topical steroids may be used if the eruption is severe and edematous. Indomethacin (50-75 mg PO qd) may be used for adults.
If a severe case evolves or greater than 30% of the body is affected, then it is recommended for the patient to be admitted to a burn unit for local wound care.
Referral to a dermatologist may be useful.
Use of UV-A sunscreens may help prevent further phototoxic reactions from occurring when exposed to sunlight.
Regular use of UV-A–blocking sunscreens may help to diminish the cutaneous effects of phytophotodermatitis (PPD) if contact with plant psoralens occurs.
Patients should avoid the offending agent.
