Ammonium Lactate

Ammonium Lactate Lotion is indicated for the treatment of dry, scaly skin (xerosis) and ichthyosis vulgaris and for temporary relief of itching associated with these conditions.

Ammonium Lactate Lotion is contraindicated in those patients with a history of hypersensitivity to any of the label ingredients.

Sun exposure to areas of the skin treated with Ammonium Lactate Lotion, 12% should be minimized or avoided (see PRECAUTIONS section). The use of Ammonium Lactate Lotion should be discontinued if hypersensitivity is observed.

Pregnancy Teratogenic effects Animal reproduction studies have been performed in rats and rabbits at doses up to 0.7 and 1.5 times the human dose respectively (600 mg/kg/day, corresponding to 3600 mg/m 2 /day in the rat and 7200 mg/m 2 /day in the rabbit) and have revealed no evidence of impaired fertility or harm to the fetus due to ammonium lactate formulations. There are, however, no adequate and well-controlled studies in pregnant women.

Because animal reproduction studies are not always predictive of human response, Ammonium Lactate Lotion should be used during pregnancy only if clearly needed.

The most frequent adverse experiences in patients with xerosis are transient stinging (1 in 30 patients), burning (1 in 30 patients), erythema (1 in 50 patients) and peeling (1 in 60 patients). Other adverse reactions which occur less frequently are irritation, eczema, petechiae, dryness and hyperpigmentation. Due to the more severe initial skin conditions associated with ichthyosis, there was a higher incidence of transient stinging, burning and erythema (each occurring in 1 in 10 patients).
