Methoxsalen is used in PUVA photochemotherapy for several dermatologic conditions.

Psoriasis: reduces plaque formation and scaling by inhibiting keratinocyte proliferation. Vitiligo: promotes repigmentation by modulating melanocyte activity and immune response. Cutaneous T‑cell lymphoma: induces apoptosis of malignant skin‑resident T cells. Other PUVA‑responsive skin disorders: improves clinical outcomes in conditions such as eczema or lichen planus.

Methoxsalen may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects: - Nausea or gastrointestinal discomfort. - Headache. - Mild erythema or skin reddening at treated sites. - Pruritus (itching). - Transient hyperpigmentation. - Phototoxic skin reactions with excessive UVA exposure.

Serious or Rare Side Effects: - Severe phototoxic burns or blistering. - Development of cutaneous squamous cell carcinoma or melanoma. - Hepatic dysfunction or elevated liver enzymes. - Severe allergic reactions, including anaphylaxis. - Persistent erythema or ulceration of treated skin.

Before using methoxsalen, several safety considerations should be observed.

Pregnancy: contraindicated due to fetal risk (Category D). Breastfeeding: avoid as drug may be excreted in milk. Photosensitivity: protect skin from UVA exposure outside controlled therapy. Renal or hepatic impairment: dose adjustment may be required; monitor function. Concomitant photosensitizing drugs: avoid simultaneous use. Store at ambient temperature: keep below 25 °C, in original container, protect from moisture and light.

Methoxsalen can interact with several medicines, influencing its efficacy or safety.

Major Interactions (Avoid): - Thiazide diuretics: increase photosensitivity risk. - Tetracyclines: potentiate phototoxic reactions. - Retinoids (e.g., isotretinoin): heighten cutaneous adverse effects.

Moderate Interactions (Monitor Closely): - Antifungal azoles: may alter methoxsalen metabolism. - Systemic corticosteroids: may reduce therapeutic response. - Anticoagulants: monitor for bleeding if skin injury occurs.
