What is Riax?
Benzoyl peroxide has an antibacterial effect. It also has a mild drying effect, which allows excess oils and dirt to be easily washed away from the skin.

Riax may also be used for purposes not listed in this medication guide.
Benzoyl peroxide can cause a rare but serious allergic reaction or severe skin irritation. Stop using Riax and get emergency medical help if you have: hives, itching; difficult breathing, feeling light-headed; or swelling of your face, lips, tongue, or throat.

How should I use Riax?
Riax can cause a rare but serious allergic reaction or severe skin irritation. Before you start using Riax, you may choose to apply a "test dose" to see if you have a reaction. Apply a very small amount of the medicine to 1 or 2 small acne areas every day for 3 days in a row. If there is no reaction, begin using the full prescribed amount on the 4th day.
Use exactly as directed on the label, or as prescribed by your doctor.
Do not take by mouth. Topical medicine is for use only on the skin. Do not use on open wounds or on sunburned, windburned, dry, or irritated skin. Also avoid using Riax on wounds or on areas of eczema. Wait until these conditions have healed before using this medication.
Wash your hands before and after applying this medication.
Clean and pat dry the skin to be treated. Apply benzoyl peroxide in a thin layer and rub in gently.
Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.
You may need to shake the medicine just before each use.
Do not cover the treated skin area unless your doctor has told you to.
