Do You Really Need Antibiotics for Acne Treatment? Expert Insights

Acne

Hello Dr.
Liao, I would like to ask if antibiotics are absolutely necessary for treating acne.
Today, I looked up the medications prescribed by my doctor: doxycycline, zinc gluconate, and Biopase for oral use, along with Stiemycin and benzoyl peroxide for topical application, all of which contain antibiotics.
Isn't it said that overusing antibiotics is not good? Although the doctor mentioned that my acne is caused by hormonal issues, why is there a need for antibiotics? Should I consider switching to another clinic? Thank you.

Dear Emma,
Acne itself is not an infectious disease, nor is it contagious, which leads some acne patients to question, "Why use antibiotics?" In your case, your physician has diagnosed your condition as being caused by hormonal factors.
Hormonal changes can promote the proliferation of Propionibacterium acnes, a type of bacteria that produces certain proteolytic enzymes.
These enzymes increase the metabolism of fatty acids within the sebaceous glands, leading to the formation of comedones and stimulating skin inflammation, resulting in pustules or papules.
This is the reason antibiotics are used in the treatment of acne: to reduce the population of P.
acnes.
While antibiotics cannot repair damaged skin, they can help minimize further skin damage by decreasing the proliferation of P.
acnes.
Combining multiple medications to treat moderate to severe acne has been shown to yield better clinical outcomes.
For topical treatments, combining antibiotics (such as the stiemicin in your prescription) with benzoyl peroxide (which is an antimicrobial agent, not an antibiotic, and promotes skin regeneration through mild keratolytic action) is a common choice among physicians.
This combination is also convenient for patients and generally produces good results.
Oral antibiotics (such as doxycycline in your prescription) are also used to treat moderate to severe acne, especially when it is widespread on the face, shoulders, back, and other areas of the body, as oral antibiotics can provide systemic effects.
The dosage of oral antibiotics can be gradually reduced from twice a day to once a day as your condition improves.
Zinc gluconate and biopase are two oral medications that primarily assist the antibacterial action of oral antibiotics while also providing astringent and anti-inflammatory effects.
Acne can indeed be bothersome, and while I may not fully understand your specific condition, please understand that following your physician's instructions regarding medication use is essential to achieving the desired treatment goals.
If you have further questions about the types of medications you are using, you should consult your physician.
I am a pharmacist, and I am providing this consultation regarding medication use.

More Info

When it comes to treating acne, the use of antibiotics can be a common and effective approach, especially in cases where the acne is moderate to severe or when it is accompanied by inflammation. However, the necessity and appropriateness of antibiotics in acne treatment can vary based on individual circumstances, and there are several factors to consider.

Understanding Acne and Its Causes
Acne is primarily caused by a combination of factors, including excess oil production, clogged hair follicles, bacteria (particularly *Propionibacterium acnes*), and inflammation. Hormonal changes, particularly during puberty, can lead to increased oil production and acne flare-ups. While antibiotics can help reduce the bacterial load and inflammation associated with acne, they are not always the first line of treatment for every patient.

Role of Antibiotics in Acne Treatment
1. Antibiotics and Their Mechanism: Antibiotics such as doxycycline and minocycline are often prescribed for acne because they can reduce the number of bacteria on the skin and decrease inflammation. They work by inhibiting bacterial growth and can also have anti-inflammatory properties. This is particularly beneficial for inflammatory acne, such as pustules and cysts.

2. Combination Therapy: In many cases, dermatologists recommend a combination of treatments. For example, topical agents like benzoyl peroxide can be used alongside oral antibiotics. Benzoyl peroxide helps to reduce bacteria and prevent the development of antibiotic resistance, which is a significant concern with prolonged antibiotic use.

3. Duration and Monitoring: The duration of antibiotic therapy for acne is typically limited to a few months. This is to minimize the risk of developing antibiotic resistance. Dermatologists often monitor patients closely and may switch to other treatments, such as topical retinoids or hormonal therapies, if necessary.

Concerns About Antibiotic Use
1. Antibiotic Resistance: One of the primary concerns with the overuse of antibiotics is the potential for developing antibiotic resistance. This means that over time, the bacteria may become resistant to the antibiotics, making them less effective. This is why it is crucial to use antibiotics judiciously and only when necessary.

2. Side Effects: Antibiotics can have side effects, including gastrointestinal upset, photosensitivity, and, in some cases, allergic reactions. It is essential to discuss any concerns about side effects with your healthcare provider.

3. Alternative Treatments: If you are concerned about using antibiotics, it is worth discussing alternative treatments with your dermatologist. Options may include topical retinoids, hormonal treatments (like oral contraceptives for women), or even newer therapies like isotretinoin for severe cases.

Conclusion
In summary, while antibiotics can be an effective part of acne treatment, they are not always necessary for every individual. The decision to use antibiotics should be based on the severity of the acne, the presence of inflammation, and the individual’s response to other treatments. If you have concerns about the treatment plan prescribed by your dermatologist, it is entirely reasonable to seek a second opinion or discuss your worries about antibiotic use and potential alternatives. Your skin health is important, and finding the right treatment plan that works for you is key to managing acne effectively.
