lifestyle
2

Sun avoidance and photoprotection

Strict avoidance of sunlight and use of broad-spectrum sunscreens, protective clothing, and UV-blocking films. Essential for photosensitive porphyrias causing cutaneous manifestations.

lifestyle
3

Beta-carotene supplementation

Oral beta-carotene to increase skin's resistance to phototoxicity. Helps reduce photosensitivity reactions and allows limited sun exposure in some patients.

medication

Additional treatment options

Red blood cell transfusion

Chronic or intermittent transfusion regimen to suppress erythropoiesis and reduce porphyrin precursor production. Used in severe erythropoietic forms.

procedure

Hematin/heme arginate

Intravenous heme preparation that suppresses ALA synthase and reduces toxic porphyrin precursor accumulation in acute porphyrias. Reserved for acute neurovisceral attacks.

medication

Dietary modifications

Appropriate nutritional support with adequate calories and carbohydrate intake. Some porphyrias improve with dietary changes and avoiding fasting.
