Written by Medicover Team and Medically Reviewed by Dr Ramchander Thorrem, Nephrology
Tacrolimus tablet is an immunosuppressive medication primarily used to prevent organ rejection in transplant patients and to treat certain skin conditions like atopic dermatitis. It works by lowering the body's immune response and reducing inflammation. In addition to the tacrolimus tablet 1 mg used in transplants, tacrolimus ointment is commonly applied for skin conditions. Both forms help control immune reactions, with the tablet offering systemic support and the ointment providing targeted relief for dermatological issues.
Tacrolimus is a calcineurin inhibitor that suppresses the immune system. It is commonly used in organ transplant patients (kidney, liver, heart) and to manage skin conditions like eczema when other treatments haven't worked. Tacrolimus tablet 1 mg is typically prescribed for transplant patients, while tacrolimus ointment is applied for eczema and other inflammatory skin issues. Tacrolimus tablet is taken orally under medical supervision to prevent organ rejection and manage immune responses effectively.
Tacrolimus is used to prevent organ rejection after kidney, liver, or heart transplants and to treat moderate to severe atopic dermatitis (eczema). It helps reduce immune system activity and skin inflammation. The uses of Tacrolimus tablets include transplant care, while the use of Tacrolimus capsules is mainly for maintaining organ function. The uses of Tacrolimus ointment focus on treating eczema and other inflammatory skin conditions.
Tacrolimus inhibits the enzyme calcineurin, which is crucial for activating T-cells involved in immune responses. By suppressing this pathway, Tacrolimus reduces inflammation and immune activity, helping prevent transplant rejection and skin flare-ups. It is commonly used in patients who have undergone organ transplants, such as kidney or liver transplants, to help the body accept the new organ. Tacrolimus is also used in some skin conditions like eczema, where reducing immune overactivity helps ease symptoms and prevent flare-ups.
Tacrolimus is available as oral capsules, extended-release tablets, granules, and topical ointment. Dosage varies based on condition and form. It is usually taken twice daily or once daily (extended-release) as directed by your doctor. Topical forms are applied in a thin layer to the affected skin.
If you miss a dose, take it as soon as you remember. If it's close to your next dose, skip the missed one and do not double up.

Yes, there are age considerations when using Tacrolimus tablets. While Tacrolimus is commonly prescribed for adults, it can also be used in children, especially after organ transplants, but only under strict medical supervision. The dosage and safety vary based on age, weight, and medical condition. It is not typically recommended for very young children unless absolutely necessary. Always consult a healthcare provider to determine if Tacrolimus is appropriate for a specific age group and medical need.
