How It Works
The ability of antibiotics to kill bacteria does not seem to be important when treating rosacea.1 Instead, the antibiotics may reduce overall inflammation of your skin. They also may reduce the number of pimples and the amount of redness around pimples.
Your doctor may prescribe antibiotics that you apply directly to the skin (topical) or that you take by mouth (oral). Both forms of antibiotics may be used together or alone to treat rosacea.
Why It Is Used
You can use antibiotics to reduce the symptoms of rosacea, including redness, pimples, and eye symptoms.
People with mild rosacea may only need antibiotic creams. Moderate or severe symptoms usually require oral antibiotics.
How Well It Works
With antibiotic treatment, symptoms usually improve in 3 to 4 weeks, with greater improvement seen in 2 months.
A low-dose form of doxycycline (Oracea) works well to clear up inflamed skin within the first few weeks. It doesn't usually cause any side effects and is available in a pill that is taken once a day.2
Oral antibiotics, such as tetracycline, are often used with good results to treat eye problems from rosacea.
All medicines have side effects. But many people don't feel the side effects, or they are able to deal with them. Ask your pharmacist about the side effects of each medicine you take. Side effects are also listed in the information that comes with your medicine.
Here are some important things to think about:
- Usually the benefits of the medicine are more important than any minor side effects.
- Side effects may go away after you take the medicine for a while.
- If side effects still bother you and you wonder if you should keep taking the medicine, call your doctor. He or she may be able to lower your dose or change your medicine. Do not suddenly quit taking your medicine unless your doctor tells you to.

What To Think About
Diarrhea and vaginal yeast infections may occur when oral antibiotics destroy some of the normal and necessary bacteria that live in the body. Eating yogurt that contains active cultures (lactobacillus) may help prevent some of these side effects.
An antibiotic that works for one person who has rosacea may not work for another.
Over time, antibiotics can stop being effective. When this occurs, a different antibiotic may be used.
Some antibiotics are not safe for pregnant women.
