  • tell your doctor and pharmacist what other prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
  • tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding. If you become pregnant while using ammonium lactate, call your doctor.

Ammonium lactate comes as a cream and a lotion to apply to the skin. It is usually applied to the affected skin area twice daily. Apply ammonium lactate at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Apply ammonium lactate exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.
Shake the lotion container well before each use to mix the medication evenly.

To use ammonium lactate topical, apply a small amount of cream or lotion to cover the affected area of skin and rub it in gently.

This medication is only for use on the skin. Keep ammonium lactate topical away from your eyes, mouth, and vaginal area, and do not swallow it.

If your skin condition becomes worse with treatment, contact your doctor.


Keep all appointments with your doctor.

Do not let anyone else use your medication. Ask your pharmacist any questions you have about refilling your prescription. If you still have symptoms after you finish your ammonium lactate topical, call your doctor.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
