Methoxsalen is a psoralen used in phototherapy protocols that target hyperproliferative and depigmented skin conditions, enhancing the therapeutic effect of UVA exposure.

- Psoriasis: reduces keratinocyte proliferation and improves plaque lesions when combined with UVA (PUVA) therapy. - Vitiligo: promotes repigmentation of depigmented patches by stimulating melanocyte activity under UVA exposure.

Methoxsalen may cause a range of adverse reactions, varying from mild to severe, particularly when combined with UVA exposure.

Common Side Effects: - Nausea: transient feeling of sickness after administration. - Headache: mild to moderate head pain. - Skin erythema: redness at the treated area. - Itching: localized pruritus.

Serious or Rare Side Effects: - Severe phototoxic reaction: blistering and extensive skin damage. - Hepatotoxicity: significant elevation of liver enzymes. - Stevens‑Johnson syndrome: rare severe skin and mucous membrane reaction.

When using Methoxsalen, several precautions should be observed to minimize risks and ensure safe administration.

- Assess liver function: perform baseline hepatic enzyme tests before therapy. - Avoid excessive sun exposure: protect untreated skin from natural UV light. - Monitor blood counts: regular CBC to detect possible hematologic effects. - Review concomitant photosensitizers: discontinue or adjust other UV‑sensitive medications. - Store at ambient temperature: keep in original container, protect from moisture and light.

Methoxsalen can interact with other medicines, altering its efficacy or increasing toxicity; awareness of these interactions is essential.

Major Interactions (Avoid): - Other photosensitizing agents: tetracyclines, sulfonamides, and thiazides may amplify phototoxicity. - Systemic retinoids: isotretinoin can increase skin sensitivity and risk of severe reactions.

Moderate Interactions (Monitor Closely): - Anticoagulants: warfarin may require INR monitoring due to potential hepatic effects. - Oral contraceptives: efficacy may be reduced; consider alternative contraception. - Antifungal azoles: ketoconazole may affect methoxsalen metabolism.
