Nemluvio is an IL-31 receptor antagonist, which means it blocks the IL-31 receptor, a key player in triggering the itch response. 

Nemluvio: Uses, Dosage, Side Effects, Instructions

In 2024, the U.S. FDA approved Nemluvio (nemolizumab-ilto), a promising treatment for prurigo nodularis, a chronic and severely itchy skin condition. 

Introduction

This breakthrough biologic therapy works by targeting interleukin-31 (IL-31), a cytokine responsible for the intense pruritus and inflammation associated with prurigo nodularis. As more individuals seek effective treatments for this debilitating condition, Nemluvio emerges as a potential solution. Below, we delve into the drug's uses, recommended dosages, potential side effects, and important instructions for safe and effective use.

What is Nemluvio?

Prurigo nodularis, characterized by raised, itchy nodules on the skin, is notoriously difficult to treat with traditional therapies. By targeting the IL-31 receptor, Nemluvio helps to reduce inflammation and the relentless itching that can make life unbearable for those affected.

Indications for Use

Nemluvio is indicated for adults with prurigo nodularis, particularly for individuals who have not responded well to other treatments. Prurigo nodularis leads to the formation of firm, itchy nodules that can cause skin damage and frequent infections. The constant urge to scratch worsens the condition and can severely impact quality of life. By blocking the pathway responsible for this extreme itching, Nemluvio provides much-needed relief and improves the overall skin condition.

Dosage and Administration

The dosage of Nemluvio is determined by a patient’s body weight. The medication is administered subcutaneously, and careful attention should be given to the injection technique and proper reconstitution of the drug. 

The general dosing guidelines are as follows:

For Adults Weighing Less Than 90 kg:

Initial Dose: 60 mg (administered as two 30 mg injections)

Maintenance Dose: 30 mg every 4 weeks (Q4W)

For Adults Weighing 90 kg or More:

Initial Dose: 60 mg (administered as two 30 mg injections)

Maintenance Dose: 60 mg every 4 weeks (Q4W)

Administration Instructions:

Injection Site: Nemluvio should be injected into the front upper thighs or abdomen, avoiding the 2-inch area around the navel. The upper arm may be used for injections but only by a healthcare provider or caregiver.

Injection Technique: Patients who have been trained may administer the injections themselves, while others should have a caregiver or healthcare professional assist. Ensure the site of injection is not tender, inflamed, or scarred to avoid irritation.

Reconstitution and Storage: Before use, Nemluvio needs to be reconstituted. The prefilled dual-chamber pen contains a lyophilized powder and a diluent. Once prepared, the solution should be clear to slightly yellow. The medication should be used within 4 hours of reconstitution.

Side Effects

As with any medication, Nemluvio may cause side effects. However, most of these effects are mild and transient.

Common Side Effects:

Headache

Atopic dermatitis

Eczema (including nummular eczema)

These side effects are generally not severe but can affect patients’ comfort and overall well-being.

Serious Side Effects:

Hypersensitivity Reactions: In rare cases, patients may experience severe allergic reactions, including facial swelling (angioedema), difficulty breathing, or hives. If these occur, it is critical to stop using the medication immediately and seek emergency medical care.

Increased Risk of Infections: Since Nemluvio affects the immune system, it could potentially increase the risk of infections. It is essential to inform healthcare providers of any existing infections or a history of frequent infections.

Other Considerations:

Live Vaccines: Patients should avoid live vaccines during treatment with Nemluvio due to potential interference with the immune system.

Injection Site Reactions: Some patients may experience redness, swelling, or irritation at the injection site. These reactions are typically mild but should be monitored.

Warnings and Precautions

1.Hypersensitivity: Nemluvio is contraindicated for those with known hypersensitivity to the drug or its components.

2.Vaccination Considerations: Ensure all vaccinations are up-to-date before starting treatment. Live vaccines should be avoided during treatment.

3.Pregnancy and Breastfeeding: The safety of Nemluvio during pregnancy and breastfeeding has not been well established. Women should consult their healthcare providers before using Nemluvio in these situations.

Nemluvio is a novel and effective treatment for prurigo nodularis, providing significant relief for patients battling severe itching and skin inflammation. With proper use and monitoring, Nemluvio can improve the quality of life for many individuals who have struggled with this condition. As always, patients should consult with their healthcare providers to determine if Nemluvio is the right choice for their treatment regimen, considering their unique health needs and medical history.
