Table of contents:

Lac-Hydrin lotion is a prescription medication used to treat symptoms of dry, scaly, or itchy skin, such as those associated with ichthyosis vulgaris or xerosis. It contains 12% ammonium lactate, which works as an emollient to help hydrate and soften the skin. It has a pH range of 4.4-5.5 and is available in a lotion formulation, which can be prescribed or purchased over the counter.

Uses and Dosage

Use Lac-Hydrin lotion regularly to get the most benefit from it. Most moisturizers need water to work well. Apply the product after bathing/showering while the skin is still damp. For very dry skin, your doctor may instruct you to soak the area before using the product. Check the label for directions about any areas or types of skin where you should not apply the product, such as on the face, any areas of broken/chapped/cut/irritated/scraped skin, or on a recently shaved area of the skin. Consult your doctor or pharmacist for more details.

  1. Before using Lac-Hydrin lotion, shake the bottle well to ensure that the active ingredients are well mixed.
  2. Check the label to see if you need to shake the bottle well before using.
  3. Apply a thin layer of the lotion to the affected areas of skin as needed or as directed on the label or by your doctor.
  4. Rub it in gently.

If you are using Lac-Hydrin lotion for diaper rash, clean the diaper area well before use and allow the area to dry before applying the product.

If you are using Lac-Hydrin lotion to treat radiation skin burns, check with radiation personnel to see if your brand can be applied before radiation therapy.

How often you apply the medication will depend on the product and your skin condition. To treat dry hands, you may need to use the product every time you wash your hands, applying it throughout the day. However, it is recommended to use Lac-Hydrin lotion twice daily or as directed by a physician.
