What is this medicine?
Tacrolimus is an immunosuppressant. It works by decreasing your body's immune system. Tacrolimus topical (for the skin) is used to treat severe atopic dermatitis (eczema).
Tacrolimus may also be used for purposes not listed in this medication guide.
What should I tell my health care providers before I take this medicine?
You should not use tacrolimus topical if you are allergic to it.
To make sure you can safely use tacrolimus topical, tell your doctor if you have any of these other conditions:
skin cancer or a skin infection (including herpes or chickenpox);
any genetic skin disorder (such as Netherton's syndrome);
a weak immune system (caused by disease or by using certain medicines);
kidney disease; or
swelling, redness, or irritation of large areas of your skin.
Tacrolimus can lower the blood cells that help your body fight infections. This can make it easier for you to get sick from a virus such as chicken pox or herpes (cold sores or shingles). Tell your doctor if you have been exposed to any illness.
Some people have developed skin cancer or lymphoma after using tacrolimus or pimecrolimus (Elidel). However, it is not known if either of these medicines causes skin cancer or lymphoma. Talk to your doctor about your individual risk.

How should I use this medicine?
Use exactly as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label. If you are using this medicine on a child younger than 16 years old, use only the 0.03% ointment. The 0.1% ointment is for adults and children who are at least 16 years old, but is too strong to use on younger children.
Wash your hands before and after using tacrolimus, unless you are using the medication to treat a hand condition. Apply the medicine in a thin layer, only to skin areas affected by eczema. Do not cover the treated skin with a bandage.
Do not bathe, shower, or swim right after applying tacrolimus topical. Water may wash off the medicine. You may need to use a moisturizing cream or lotion to keep your skin from getting too dry. Ask your doctor about which moisturizer to use.
Tacrolimus is not for long-term use. Stop using the medicine once your symptoms have cleared up, unless your doctor has told you otherwise. Call your doctor if your symptoms do not improve after 6 weeks of treatment, or if they get worse while using tacrolimus. Store at room temperature. Do not freeze. Keep ointment tube tightly closed when not in use.
What if I miss a dose?
Apply the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
