Berdazimer Topical

pronounced as (ber daz′ i mer soe′ dee um)

Why is this medication prescribed?

Berdazimer topical is used to treat molluscum contagiosum (MC; infection caused by a virus that causes little bumps to form on skin anywhere on the body) in adults and children over the age of 1 year. Berdazimer is in a class of medications called nitric oxide releasing agents. How it works to treat MC is not fully understood.

How should this medicine be used?

Berdazimer comes as a gel to be applied to the affected areas of the skin. It is usually applied to each MC skin lesions once daily for up to 12 weeks. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use berdazimer exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.

Berdazimer comes as two tubes and a dosing guide. Squeeze out an equal amount from each tube onto the dosing guide. Follow the directions on the dosing guide for how much berdazimer to apply to the dosing guide. Replace the caps on both tubes tightly and mix together on the dosing guide. Apply berdazimer as a thin layer on all MC lesions. Wash hands (unless treating lesions on hands) and avoid touching eyes or transferring gel to unaffected parts of the body. Allow berdazimer to dry for 10 minutes and avoid swimming, bathing or washing for 1 hour after applying.

Do not apply berdazimer in or around the eyes or place in the mouth or vagina.

Only mix berdazimer right before applying. Discard any unused mixed berdazimer. Do not store for later use.

Take berdazimer for as long as instructed to by your physician to ensure complete clearance of lesions.

What should I know about storage and disposal of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Discard unused portion after 60 days.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach.

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( for more information if you do not have access to a take-back program.

What other information should I know?

Keep all appointments with your doctor.

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
