Klisyri (tirbanibulin) is a topical Src kinase inhibitor employed in dermatologic practice for the management of premalignant skin lesions caused by chronic sun exposure.

- Actinic keratosis of the face: reduces precancerous lesions on facial skin. - Actinic keratosis of the scalp: clears lesions on the scalp area. - Field‑directed therapy for actinic keratosis: treats multiple lesions within a treated area, improving overall lesion burden.

Klisyri may cause local skin reactions, most of which are mild to moderate and resolve after treatment.

Common Side Effects: - Erythema: redness at the application site. - Crusting: formation of a dry scab over treated lesions. - Pruritus: itching of the treated area. - Pain or tenderness: discomfort during or after application. - Swelling: mild edema around the lesion. - Dryness or flaking of skin.

Serious or Rare Side Effects: - Severe allergic reaction: hives, swelling, or difficulty breathing. - Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Bullous dermatitis: blister formation. - Secondary skin infection at the site. - Persistent ulceration or necrosis. - Uncontrolled pain requiring medical attention.

Before using Klisyri, consider the following safety measures.

- Pregnancy: safety not established; avoid use unless clearly needed. - Breastfeeding: unknown risk; weigh benefits against potential exposure. - Application site: apply only to intact skin; avoid eyes, mucous membranes, and open wounds. - Surface area: do not exceed the prescribed treatment area or duration. - Monitoring: discontinue and seek medical advice if severe local reactions develop. - Store at room temperature: keep in the original container, protect from light and moisture.

Klisyri has limited systemic absorption, but certain topical or systemic agents may influence its safety or efficacy.

Major Interactions (Avoid): - Concurrent use of other topical chemotherapeutic agents on the same area: may increase irritation. - Systemic immunosuppressants: could impair wound healing.

Moderate Interactions (Monitor Closely): - Topical corticosteroids applied to the same site: may reduce tirbanibulin efficacy. - Phototherapy or intense UV exposure: may heighten skin sensitivity. - Co‑application with other keratolytic agents: may enhance local irritation.
