What is Rozex?

Rozex is a cream which is used to treat rosacea. It helps reduce facial redness, flushing and small red spots.

How does Rozex work?

Rozex contains metronidazole, which is an antibiotic. It helps reduce redness and inflammation. It also stops bacteria, which cause inflammation, from growing.

How long will Rozex take to work?

Rozex will usually take a few weeks to work. It's important to keep using Rozex regularly to see an improvement in your skin.

How long can I use Rozex for?

Rozex should be used for as long as your doctor has prescribed. Stopping the treatment early could mean you don't see an improvement in your skin, and the rosacea will come back.

How to use Rozex

Rozex should be used twice a day to treat rosacea. Apply a thin layer of Rozex to clean, dry skin and rub into all affected areas. Wash your hands after use.

What should I do if I use too much Rozex?

Using too much Rozex is unlikely to cause any problems. It may make you more likely to experience side effects or skin irritation. Using more Rozex than you need will not  cause redness to disappear any faster.

What should I do if I forget to use Rozex?

If you forget to use Rozex, apply it as soon as you remember or wait until you are next due to use it. Rozex doesn't have to be used at exactly the same time each day as long as it is applied twice daily.

How long should I use Rozex for?

Always use Rozex for the length of time specified by your doctor. This is usually three to four months.

Drug interactions

Anticoagulants and blood thinners may be affected by Rozex. Ask your doctor for advice if this applies to you.

Rozex and alcohol

Treatment Options

Alternatives to Rozex

There are different types of treatments for rosacea which you can try if Rozex is not suitable for you. These are Finacea gel, ivermectin cream and brimonidine. Oral antibiotics may be prescribed if creams such as Rozex have not been successful and isotretinoin tablets can be given to treat severe cases of rosacea. You could try laser treatment as an alternative.

Rozex vs metronidazole

Metronidazole is the generic name for antibiotic medicine. Rozex is a brand that contains metronidazole as the active ingredient, so the two are essentially the same medicine.

Rozex vs Finacea Gel

Rozex contains the antibiotic metronidazole, while Finacea gel contains azelaic acid. If you experience skin irritation while using Rozex, then Finacea gel may be prescribed as an alternative.


Can I wear makeup while using Rozex?

You can still wear makeup while using Rozex. Wait for the cream to be absorbed by your skin before applying makeup.

What kind of foundation can I use to cover redness caused by rosacea?

Foundation or bases which have a green tint work best to cover up and even out redness. Camouflage makeup is available to provide a stronger coverage. Brands such as Dermablend are specifically formulated for people with skin conditions or sensitive skin and will not irritate the skin further.
