Before taking this medicine

How should I use Onexton?
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Using more medicine or applying it more often than prescribed will not make it work any faster, and may increase side effects.
Benzoyl peroxide can cause a rare but serious allergic reaction or severe skin irritation. Before you start using this medicine, 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.
Wash your hands before and after applying this medicine.
Wash your face with a mild cleanser (not soap) and pat the skin dry with a clean towel.
Onexton is usually applied twice daily, in the morning and evening.
Avoid getting this medicine in your eyes, mouth, or nose (or in the creases of your nose), or on your lips. If it does get into any of these areas, wash with water. Do not apply this medicine to sunburned, windburned, dry, chapped, irritated, or broken skin.
It may take several weeks before your symptoms improve. Keep using the medication as directed and tell your doctor if your symptoms do not improve.
If you receive more than one supply of Acanya or Duac gel, store the unopened container in a refrigerator until you are ready to start using it. Do not freeze.
Once in use, store the gel at room temperature away from moisture and heat. Do not freeze. Throw away any unused medicine after the expiration date on the label has passed. Duac has an expiration date of 60 days. Acanya has an expiration date of 10 weeks. BenzaClin has an expiration date of 3 months.
What happens if I miss a dose?
Apply the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
Overdose symptoms include bloody or watery diarrhea, which may result if you absorb this medicine through your skin by applying too much.
What should I avoid while taking Onexton?
Avoid using skin products that can cause irritation, such as harsh soaps, shampoos, or skin cleansers, hair coloring or permanent chemicals, hair removers or waxes, or skin products with alcohol, spices, astringents, or lime.
Avoid using other medications on the areas you treat with Onexton unless your doctor tells you to.
Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or bloody, stop using Onexton and call your doctor. Do not use anti-diarrhea medicine unless your doctor tells you to.
Avoid using sunscreen containing PABA on the same skin treated with Onexton, or skin discoloration may occur.
Benzoyl peroxide can bleach hair or fabrics. Do not let this medicine come into contact with clothing, hair, or colored towels or bed linens.
