Litfulo 50 mg/1 (Ritlecitinib CAPSULE) 50 mg/1

Litfulo is primarily used to treat severe alopecia areata, a condition that causes significant hair loss. It works by targeting specific inflammatory proteins involved in the immune response that attacks hair follicles.

• Alopecia areata: Reduces hair loss and promotes hair regrowth in adults and adolescents 12 years and older.
• Severe alopecia areata: Helps achieve significant scalp hair coverage, including eyelash and eyebrow regrowth.
• Immune-mediated hair loss: Targets the underlying inflammatory processes that contribute to hair loss.

• Litfulo works by selectively inhibiting Janus kinase 3 (JAK3) and TEC family kinases. These kinases are critical in signaling pathways that regulate immune cell activity and cytokine production. By blocking these kinases, Litfulo disrupts the communication that prompts immune cells to attack hair follicles, thereby reducing inflammation and allowing hair follicles to recover and regrow hair.

Litfulo can cause various side effects, ranging from common to serious. Common side effects include mild to moderate symptoms, while serious or rare side effects are less frequent but more severe.

Common Side Effects

• Headache: A frequent side effect reported by users.
• Diarrhea: May occur during treatment.
• Acne: Skin-related side effects are possible.
• Rash: Including urticaria and atopic dermatitis.
• Fever: Mild to moderate fever may be experienced.
• Dizziness: Some users may feel lightheaded.

Serious or Rare Side Effects

• Serious infections: Increased risk of infections due to immune system suppression.
• Blood clots: Higher rate of blood clot formation.
• Cancer: Increased risk of developing certain types of cancer.
• Heart attack and stroke: Higher rate of cardiovascular events.

Litfulo should be used with caution and under the supervision of a healthcare provider. Important precautions include monitoring for infections, cardiovascular events, and other serious side effects.

• Infections: Monitor for signs of infection and seek medical attention if symptoms occur.
• Cardiovascular events: Regularly check for signs of heart attack or stroke.
• Cancer: Be aware of the increased risk of cancer and report any unusual symptoms.

Litfulo can interact with other medications, potentially affecting its efficacy or increasing the risk of side effects. Major interactions should be avoided, while moderate interactions require close monitoring.

Major Interactions (Avoid)

• Immunosuppressants: Avoid concurrent use with other immunosuppressants to prevent excessive immune suppression.
• Anticoagulants: Avoid concurrent use to prevent an increased risk of bleeding.
• Biologics: Avoid concurrent use to prevent excessive immune suppression.

Moderate Interactions (Monitor Closely)

• NSAIDs: Monitor for increased risk of gastrointestinal side effects.
• Corticosteroids: Monitor for increased risk of infections and other side effects.
• Antidiabetics: Monitor blood sugar levels closely.
