We’re here to share what we know — but don’t take it as medical advice. Talk to your medical provider if you have questions.

If you’re dealing with acne that’s resistant to the usual topical treatments, your dermatology provider may recommend additional oral prescription medications for more help. And one such treatment is minocycline, an oral prescription antibiotic that is in a class of antibiotics called tetracyclines. Tetracycline medications treat a wide variety of conditions, including Lyme disease.¹ Healthcare providers often use it for cases of moderate to severe acne or even rosacea with lower doses. 

We believe that knowledge is power, especially when it comes to your skin health. So, we’ve tapped our licensed dermatology providers to share everything you need to know about minocycline for acne, if you’re considering this treatment: its efficacy, potential side effects, and risks. Let’s get into it.

What does minocycline do for acne?

When discussing minocycline as an oral antibiotic for acne, it’s important to know how it works! Minocycline fights the C. acnes bacteria (a strain that causes acne).² It's recommended as part of a combination treatment with a topical medication.³ So, for the best results, your healthcare provider will likely recommend topical acne medications as well. 

How long does it take for minocycline to work?

Exactly how long you take minocycline will depend on your medical provider’s exact recommendations. Often, patients take the antibiotic for 2-3 months, but results can come sooner. When taking oral minocycline, many acne patients see moderate improvement in 6 to 8 weeks of treatment.⁴ Overall, clearer skin takes a little patience, but the results are usually worth it! A review of multiple studies showed that patients experienced anywhere from a 22% to a 91% reduction in inflammatory lesions with minocycline.⁵ Clearer skin doesn't mean you should stop the medication, though. It is recommended to finish your entire round of antibiotics as prescribed by your healthcare provider.

What is the proper minocycline dose for acne?

Oral minocycline often comes in extended-release tablets or capsules. Like all medications, the dosage varies depending on each patient's specific needs and medical history. In general, expect to take about 50mg to 100mg per dose as an adult.⁶ Minocycline also comes in pellets, immediate release, and topical treatment options. Each form has its own dosages and directions for use. Whatever version you get, use it as prescribed and do let your medical provider know if you have any questions or concerns. 

What are the side effects of minocycline for acne?

When taking minocycline for acne, side effects are possible. Side effects of minocycline can include:⁷ 

  • Headache

  • Dizziness

  • Ringing in the ears

  • Itchiness

  • Diarrhea 

A few people may have serious side effects. Especially in long-term use, rare adverse effects may include:⁸

  • Kidney or liver dysfunction

  • Lupus-like syndrome

  • Pseudotumor cerebri (idiopathic intracranial hypertension)

Tell your healthcare provider if you're pregnant, trying to conceive, or breastfeeding. Other risks include irritation or damage to the esophagus (esophagitis or esophageal perforation).⁹ If you experience any side effects, let your provider know right away as common side effects such as headache or dizziness can vary from benign to severe causes that cannot be fully evaluated without the help of a medical professional. This is not a full list of side effects that can be caused by minocycline. Always seek medical advice when it comes to side effects. As with all medications, watch for allergic reactions. In addition, as minocycline can cause photosensitivity, you may also want to limit exposure to sunlight and avoid tanning beds (though we always recommend doing so!).¹⁰

Do minocycline side effects go away?

Most side effects do go away in time. Some may not go away on their own, though. As mentioned above, if you have any reactions, tell your medical provider even if it might seem as though it’s not a big deal (for example, more frequent headaches). Your medical provider will advise on any next steps. Unfortunately, some serious side effects may not be reversible.¹¹ Staining of the teeth may be permanent. Due to side effects, this medication isn’t for children under 12 whose teeth are still developing.¹² 

Scientists are working to reduce the negative effects. Extended-release tablets typically have fewer side effects than the immediate-release version.¹³

What medications react with minocycline?

Minocycline does interact with certain medications. Tell your healthcare provider about every medication you take (including vitamins and/or supplements), especially if you use:

  • Blood thinners

  • Birth control pills: Let your medical provider know if you use oral contraceptives or hormonal birth control, as you may need to use another form of birth control while you're on minocycline.¹⁴

Iron, magnesium, aluminum, and calcium containing products may interfere with minocycline.¹⁵ Remember to inform your dermatology provider if you take vitamins, herbal supplements, or nonprescription remedies.

Remember, you can manage or prevent acne in other ways. You can start by creating a good skincare routine with over-the-counter methods. Or, you can see if Curology is right for you!

FAQs

What is minocycline used for?

Minocycline is a broad-spectrum antibiotic. In other words, it fights different kinds of bacteria. It treats infections such as Rocky Mountain spotted fever, Lyme disease, and more.¹⁶ It can also be used in the treatment of acne.

How good is minocycline for acne?

Studies have demonstrated that minocycline is effective for treating moderate to severe acne. Patients saw moderate improvement within 12 weeks of treatment.¹⁷ That said, other antibiotics may be more appropriate than minocycline in the treatment of acne. It is important to discuss your options with a licensed medical provider.

Will acne come back after minocycline?

Unfortunately, yes, it could. Some patients with acne may need several rounds of antimicrobial therapy. Oral antibiotics generally shouldn't be used long-term for acne treatment. There are risks when you stay on antibiotics for a while. There's more of a chance of bacterial resistance¹⁸ or side effects.
