1. What is Cellmune and what is it used for

The active substance in Cellmune, tacrolimus monohydrate, is an immunomodulating agent.

Cellmune is used to treat moderate to severe atopic dermatitis (eczema) in adults who do not respond adequately to or are intolerant of conventional treatments, such as topical corticosteroids.

Once the moderate to severe atopic dermatitis has disappeared or almost disappeared after up to 6 weeks of treatment for a flare, and if you have frequent flares (i.e., 4 or more per year), you can prevent flares from coming back or prolong the time without flares by using Cellmune twice a week.

In atopic dermatitis, the skin's excessive immune reaction causes skin inflammation (itching, redness, dryness). Cellmune modifies the abnormal immune response and relieves skin inflammation and itching.

2. What you need to know before you use Cellmune

Do not use Cellmune

• If you are allergic (hypersensitive) to tacrolimus or any of the other ingredients of Cellmune (listed in section 6), or to macrolide antibiotics (e.g., azithromycin, clarithromycin, erythromycin).

Warnings and precautions

Consult your doctor if:

• you have liver failure.
• you have any skin malignancy(tumors) or if you have a weakened immune system(immunocompromised), regardless of the cause.
• you have a hereditary skin barrier disease, such as Netherton syndrome, lamellar ichthyosis (widespread scaling of the skin due to thickening of the outer layer of the skin), if you have an inflammatory skin disease such as pyoderma gangrenosum or if you suffer from generalized erythroderma(inflammatory redness and scaling of the entire skin).
• you have a skin graft-versus-host disease (an immune reaction of the skin, which is a common complication in patients who have undergone a bone marrow transplant).
• you have inflamed lymph nodesat the start of treatment. If your lymph nodes become inflamed during treatment with Cellmune, consult your doctor.
• if you have infected lesions. Do not apply the ointment to infected lesions.
• if you notice any change in the appearance of your skin; please inform your doctor.

• The safety of using tacrolimus for a long period of time is unknown. A very small number of people who have used tacrolimus ointment have had malignant diseases (e.g., skin or lymphoma). However, it has not been confirmed or ruled out, according to the available evidence, whether there is a relationship with tacrolimus treatment.
• Avoid prolonged exposure of your skin to sunlight or artificial light, such as tanning beds. If you stay outdoors after applying Cellmune, use a sunscreen and wear loose clothing that protects your skin from the sun. Also, consult your doctor for other suitable methods to protect yourself from the sun. If you are prescribed light therapy, inform your doctor that you are using Cellmune, as it is not recommended to use Cellmune and light therapy at the same time.
• If your doctor tells you to use Cellmune twice a week to maintain the disappearance of your atopic dermatitis, your condition should be reviewed by your doctor at least every 12 months, even if it remains controlled. In children, maintenance treatment should be discontinued after 12 months to assess whether there is still a need for continued treatment.
• Patients should be informed not to bathe, shower, or swim immediately after applying the ointment; water may remove the medication.

Children

• Cellmune 1 mg/g ointment is not authorized for children under 16 years of age. Therefore, it should not be used in this age group. Please consult your doctor.
• The effect of treatment with Cellmune on the development of the immune system in children, especially in younger children, has not been established.

Using Cellmune with other medicines and cosmetics

Tell your doctor or pharmacist if you are taking or using or have recently taken or used any other medicines, including those obtained without a prescription.

You can use moisturizing creams and lotions during treatment with Cellmune, but you should not use them during the 2 hours before and 2 hours after applying Cellmune.

The use of Cellmune at the same time as other topical preparations or while taking oral corticosteroids (e.g., cortisone) or oral immunosuppressive medications has not been studied.

Using Cellmune with alcohol

While using Cellmune, alcohol consumption may cause redness or flushing of the skin or face and a feeling of warmth.

Consult your doctor or pharmacist before using any medicine.

3. How to use Cellmune

Follow your doctor's instructions for using Cellmune exactly. If you are unsure, consult your doctor or pharmacist.

• Apply Cellmune as a thin layer to the affected areas of your skin.
• Cellmune can be used on most parts of the body, including the face and neck and in the folds of the elbows and knees.
• Avoid using the ointment inside your nose or mouth, or in your eyes. If ointment gets into any of these areas, you should remove it by gently rubbing and/or rinsing with water.
• Do not cover the treated skin with bandages or other wound dressings.
• Wash your hands after applying Cellmune, unless your hands are also being treated.
• Before applying Cellmune after a bath or shower, make sure your skin is completely dry.
• Do not bathe, shower, or swim immediately after applying the ointment. Water may remove the medication.

Adults (16 years of age and older)

For adult patients (16 years of age and older), two doses of tacrolimus ointment are available (tacrolimus 0.3 mg/g ointment and tacrolimus 1 mg/g ointment). Your doctor will decide which dose is most suitable for you.

Typically, treatment is started with Cellmune 1 mg/g ointment twice a day, once in the morning and once in the evening, until the eczema disappears. Depending on the response of your eczema, your doctor will decide if the application frequency can be reduced or if the lower dose, tacrolimus 0.3 mg/g ointment, can be used.

Treat each affected area of your skin until the eczema has disappeared. Improvement is usually seen within a week. If you do not see any improvement after two weeks, consult your doctor about other possible treatments.

Your doctor may tell you to use Cellmune 1 mg/g ointment twice a week once your atopic dermatitis has disappeared or almost disappeared. Cellmune 1 mg/g ointment should be applied once a day, twice a week (e.g., Monday and Thursday) to the areas of your body that are usually affected by atopic dermatitis. There should be 2-3 days without treatment with Cellmune between applications. If symptoms come back, you should use Cellmune twice a day, as previously indicated, and go see your doctor to review your treatment.

If you accidentally ingest some ointment

If you accidentally ingest the ointment, consult your doctor or pharmacist as soon as possible. Do not try to induce vomiting.

If you forget to use Cellmune

If you forget to apply the ointment at the scheduled time, do so as soon as you remember and then continue as before.

If you have any other questions about using this medicine, ask your doctor or pharmacist.
