Tacrolimus injection is used together with other medicines to prevent the body from rejecting a transplanted organ (eg, kidney, liver, or heart). This medicine may be used with steroids, azathioprine, or mycophenolate mofetil. Tacrolimus belongs to a group of medicines known as immunosuppressive agents.

When a patient receives an organ transplant, the body's white blood cells will try to get rid of (reject) the transplanted organ. Tacrolimus works by suppressing the immune system to prevent the white blood cells from trying to get rid of the transplanted organ.

Tacrolimus is a very strong medicine. It can cause side effects that can be very serious, such as kidney problems. It may also decrease the body's ability to fight infections. You and your doctor should talk about the benefits of this medicine as well as the risks of using it.

This medicine is to be given only by or under the direct supervision of a doctor.

Adjunct in the cessation of cigarette smoking.

USPHS guideline for the treatment of tobacco use and dependence recommends varenicline as one of several first-line drugs that may reliably increase long-term smoking abstinence rates.

In clinical studies, varenicline therapy increased continuous abstinence rates compared with placebo or active comparator (e.g., bupropion). Also reduced urge to smoke.

In studies in patients with stable, documented cardiovascular disease and patients with mild to moderate COPD, efficacy of varenicline was comparable to that in the general smoking population without these conditions.

Also evaluated in patients with stable major depressive disorder in a postmarketing study; benefits also observed in this population without evidence of increased neuropsychiatric effects. (See Neuropsychiatric Symptoms and Suicidality under Cautions.)

Efficacy and safety of varenicline given in conjunction with other smoking cessation therapies (e.g., bupropion, nicotine replacement therapy) not established.
