Vexlimus Special Precautions

Exposure of the skin to sunlight should be minimised and the use of ultraviolet (UV) light from a solarium, therapy with UVB or UVA in combination with psoralens (PUVA) should be avoided during use of Tacrolimus ointment. Physicians should advise patients on appropriate sun protection methods, such as minimisation of the time in the sun, use of a sunscreen product and covering of the skin with appropriate clothing. Tacrolimus ointment should not be applied to lesions that are considered to be potentially malignant or pre-malignant.
The development of any new change different from previous eczema within a treated area should be reviewed by the physician.
The use of tacrolimus ointment is not recommended in patients with a skin barrier defect, such as Netherton's syndrome, lamellar ichthyosis, generalized erythroderma or cutaneous Graft Versus Host Disease. These skin conditions may increase systemic absorption of tacrolimus. Oral use of tacrolimus is also not recommended to treat these skin conditions.
Post-marketing cases of increased tacrolimus blood level have been reported in these conditions.
Care should be exercised if applying Tacrolimus ointment to patients with extensive skin involvement over an extended period of time, especially in children. Patients, particularly paediatric patients should be continuously evaluated during treatment with Tacrolimus ointment with respect to the response to treatment and the continuing need for treatment. After 12 months this evaluation should include suspension of Tacrolimus ointment treatment in paediatric patients.
The potential for local immunosuppression (possibly resulting in infections or cutaneous malignancies) in the long term (i.e. over a period of years) is unknown.
Tacrolimus ointment contains the active substance tacrolimus, a calcineurin inhibitor. In transplant patients, prolonged systemic exposure to intense immunosuppression following systemic administration of calcineurin inhibitors has been associated with an increased risk of developing lymphomas and skin malignancies. In patients using tacrolimus ointment, cases of malignancies, including cutaneous (i.e. cutaneous T Cell lymphomas) and other types of lymphoma, and skin cancers have been reported. Tacrolimus ointment should not be used in patients with congenital or acquired immunodeficiencies or in patients on therapy that cause immunosuppression.
Patients with atopic dermatitis treated with Tacrolimus ointment have not been found to have significant systemic tacrolimus levels.
Lymphadenopathy was uncommonly (0.8%) reported in clinical trials. The majority of these cases were related to infections (skin, respiratory tract, tooth) and resolved with appropriate antibiotic therapy. Transplant patients receiving immunosuppressive regimens (e.g. systemic tacrolimus) are at increased risk for developing lymphoma; therefore patients who receive Tacrolimus ointment and who develop lymphadenopathy should be monitored to ensure that the lymphadenopathy resolves. Lymphadenopathy present at initiation of therapy should be investigated and kept under review. In case of persistent lymphadenopathy, the aetiology of the lymphadenopathy should be investigated. In the absence of a clear aetiology for the lymphadenopathy or in the presence of acute infectious mononucleosis, discontinuation of Tacrolimus ointment should be considered.
The effect of treatment with Tacrolimus ointment on the developing immune system of children aged below 2 years has not been established.
Tacrolimus ointment has not been evaluated for its efficacy and safety in the treatment of clinically infected atopic dermatitis. Before commencing treatment with Tacrolimus ointment, clinical infections at treatment sites should be cleared. Patients with atopic dermatitis are predisposed to superficial skin infections. Treatment with Tacrolimus ointment may be associated with an increased risk of folliculitis and herpes viral infections (herpes simplex dermatitis [eczema herpeticum], herpes simplex [cold sores], Kaposi's varicelliform eruption). In the presence of these infections, the balance of risks and benefits associated with Tacrolimus ointment use should be evaluated.
Emollients should not be applied to the same area within 2 hours of applying Tacrolimus ointment. Concomitant use of other topical preparations has not been assessed. There is no experience with concomitant use of systemic steroids or immunosuppressive agents.
Care should be taken to avoid contact with eyes and mucous membranes. If accidentally applied to these areas, the ointment should be thoroughly wiped off and/or rinsed off with water.
The use of Tacrolimus ointment under occlusion has not been studied in patients. Occlusive dressings are not recommended.
As with any topical medicinal product, patients should wash their hands after application if the hands are not intended for treatment. Tacrolimus is extensively metabolised in the liver and although blood concentrations are low following topical therapy, the ointment should be used with caution in patients with hepatic failure.
