Rosacea Treatment:

Oral Antibiotics - Tetracycline

Tetracycline is one of the early broad spectrum antibiotics developed in 1953. Since then, several derivative antibiotics such as doxycycline and minocycline have been developed and are classified as tetracycline antibiotics. Characteristically tetracycline antibiotics are low cost, and have very few serious side-effects, making them first line antibiotic treatments. Although rosacea is not a bacterial infection, many antibiotics have anti-inflammatory properties, helping to reduce many of the problematic symptoms of rosacea such as redness, and pimples.


Tetracycline should be taken at least two hours after the last meal and should not be taken with antacids or milk.

Expected results:

Results vary depending on the specific type of tetracycline antibiotic that is used, as well as the patient's rosacea severity. Unlike treating bacterial infections, the effect of antibiotics are gradual, taking weeks to months.

How it works:

Generally, the anti-inflammatory effects are the key points in reducing rosacea symptoms.


Gastrointestinal upset, sun sensitivity, and pigmentation problems are some of the more common side-effects. Generally, discontinuation of the drug will stop further problems.
