Tacrolimus ointment: Uses, How to Use it, Side Effects, Interactions

Tacrolimus ointment belongs to a broad class of medications known as immunosuppressants. It works by decreasing the activity of the immune system to prevent it from attacking the transplanted organ. Tacrolimus ointment is used to treat the symptoms of eczema (atopic dermatitis; a skin disease that causes the skin to be dry and itchy and to sometimes develop red, scaly rashes) in patients who cannot use other medications for their condition or whose eczema has not responded to another medication.

How tacrolimus ointment works

People with eczema tend to have an over-reactive immune system. When triggered by a substance inside or outside the body, the immune system responds by producing inflammation. It is this inflammatory response that causes the itchy, painful, rash-like symptoms common to several types of eczema. Tacrolimus is in a sub-class of medications called topical calcineurin inhibitors. It works by stopping the immune system from producing substances that may cause eczema.

How effective is tacrolimus ointment for eczema?

Studies have shown that both tacrolimus strengths (0.03% and 0.1%) ointments are superior to low-potency topical corticosteroids, whereas tacrolimus 0.1% has similar effectiveness to moderate- to high-potency topical corticosteroids. A mild, self-limited, local burning sensation is common with use.

How should tacrolimus ointment be used?

Tacrolimus comes as an ointment to apply to the skin. It is usually applied twice a day to the affected area. To help you remember to apply tacrolimus ointment, apply it at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use tacrolimus exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.

To use the ointment, follow these steps:

• Wash your hands with soap and water.
• Be sure that the skin in the affected area is dry.
• Apply a thin layer of tacrolimus ointment to all affected areas of your skin.
• Rub the ointment into your skin gently and completely.
• Wash your hands with soap and water to remove any leftover tacrolimus ointment. Do not wash your hands if you are treating them with tacrolimus.

You may cover the treated areas with normal clothing, but do not use any bandages, dressings, or wraps.

Be careful not to wash the ointment off of affected areas of your skin. Do not swim, shower, or bathe immediately after applying tacrolimus ointment.

What should I do if I forget a dose?

Apply the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not apply extra ointment to make up for a missed dose.

What if I overdose?

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can’t be awakened, immediately call emergency services at 911.

What are the side effects of tacrolimus ointment?

Tacrolimus ointment may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:

• acne
• flu-like symptoms
• headache
• increased sensitivity of the skin to hot or cold temperatures
• itching
• muscle or back pain
• nausea
• skin burning, stinging, redness or soreness

Tacrolimus ointment may cause other side effects. Call your doctor if you have any unusual problems while taking this medication.

If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration’s (FDA) MedWatch Adverse Event Reporting program online (http://www.fda.gov/Safety/MedWatch) or by phone (1-800-332-1088).
