What is Boudreaux's Butt Paste?

Boudreaux's Butt Paste contains zinc oxide. When applied to the skin zinc oxide forms a temporary barrier protecting the skin from external irritants. It also decreases inflammation and reduces bacterial growth in injured skin.

Boudreaux's Butt Paste is used to treat diaper rash and other minor skin irritations.

Boudreaux's Butt Paste may also be used for purposes not listed in this medication guide.


Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

How should I use Boudreaux's Butt Paste?

Use Boudreaux's Butt Paste exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

Do not take by mouth. Boudreaux's Butt Paste is for use only on the skin.

Apply enough of this medication to cover the entire area to be treated. Zinc oxide often leaves a thin white residue that may not be entirely rubbed in.

To treat chapped skin, minor burn wounds, or other skin irritations, use the medication as often as needed. Apply a thin layer to the affected area and rub in gently.

To treat diaper rash, use Boudreaux's Butt Paste each time the diaper is changed. It is especially important to apply the medication at bedtime or whenever there will be a long period of time between diaper changes.

Keep the diaper area clean and dry to prevent worsening of skin rash. Change wet diapers as soon as possible. Allow the skin to dry thoroughly before putting on a fresh diaper.

Store at room temperature away from moisture and heat. Keep the tube cap tightly closed when not in use.
