What is Tacrolimus?
Tacrolimus is an immunosuppressant that helps calm your immune system to treat chronic conditions like vitiligo. Vitiligo is a skin condition that causes depigmentation, resulting in discolored white patches across your body.
Although the patches arenโt painful, their appearance can impact someoneโs self-esteem. By reducing the effects of an overactive immune system on skin pigmentation, Tacrolimus can help prevent further depigmentation and improve the symptoms of vitiligo.
Tacrolimus ointment is used off-label for vitiligo, although itโs FDA-approved for atopic dermatitis. Off-label prescribing is a common practice, and your doctor will only recommend this medication if they believe it will be safe and effective for you.
How does Tacrolimus work?
Tacrolimus works by calming the immune system. Vitiligo is caused by an overactive immune system that mistakenly targets your body’s cells as dangerous. It destroys melanocytes, the cells that produce melanin, resulting in skin discoloration.
By inhibiting the release of immune cells, Tacrolimus can help prevent further skin discoloration and repigment skin.1
Does Tacrolimus cause side effects?
You may experience side effects while taking Tacrolimus, although not everyone will. Common side effects include:
- Redness
- Pain
- Skin sensitivity
- Skin tingling
- Rash
- Local skin reaction
These side effects should be mild and tolerable, but if they worsen or persist, contact your doctor. They may lower your dose or suggest an alternative treatment.
Is Tacrolimus a steroid?
No, the active ingredient tacrolimus isnโt a steroid, although it works in a similar way. Tacrolimus is a topical calcineurin inhibitor that calms your immune system to stop it from attacking your own body cells. While this action is similar to that of a steroid, it belongs to a different drug class.
What doses of Tacrolimus are there?
Tacrolimus comes as a 0.1% dose. Itโs applied to the affected areas twice daily.
