antibiotics for acne side effects | Important Points

Antibiotics are a common treatment for acne, but like any medication, they can come with side effects. While antibiotics can be effective in treating moderate to severe acne, they can also wreak havoc on the body — from the digestive system to the immune system.

Antibiotics work by killing off bacteria in the body, including the bacteria that contribute to acne. However, some bacteria can become resistant to antibiotics, which means that it can take longer to see results from the medication. In addition, antibiotics can have a range of side effects that can be unpleasant, uncomfortable, and in some cases, even dangerous. Let’s take a closer look at some of the side effects of antibiotics for acne.

Digestive problems

One of the most common side effects of antibiotics is digestive upset. Antibiotics can disrupt the natural balance of bacteria in the gut, leading to issues like diarrhea, nausea, vomiting, and bloating. These side effects can be temporary or persist throughout the course of treatment.

In some cases, antibiotics can cause more serious digestive problems, like colitis or Clostridium difficile (C. diff) infection. This occurs when the antibiotics kill off both good and bad bacteria in the gut, allowing harmful bacteria like C. diff to grow unchecked. Symptoms of C. diff infection include severe diarrhea, abdominal pain, and dehydration, and it can be life-threatening if not treated promptly.

Allergic reactions

Like any medication, antibiotics can cause allergic reactions in some people. Symptoms of an allergic reaction can range from mild to severe and include hives, itching, swelling of the face, tongue, or throat, difficulty breathing, and anaphylaxis (a potentially life-threatening reaction). If you experience any of these symptoms after taking antibiotics, seek medical attention immediately.


Certain antibiotics like doxycycline and tetracycline can make your skin more sensitive to the sun’s UV rays. This can lead to sunburn, blistering, and other skin damage if you do not take steps to protect your skin. It’s important to wear sunscreen with an SPF of at least 30, wear protective clothing like hats and long sleeves, and avoid prolonged sun exposure while taking these antibiotics.

Yeast infections

Antibiotics can disrupt the balance of bacteria in the body, leading to an overgrowth of yeast. This can result in a yeast infection, which can cause itching, burning, discharge, and discomfort. Women are particularly prone to yeast infections while taking antibiotics, as the medication can disrupt the delicate balance of bacteria in the vagina.


Antibiotic resistance is a growing problem worldwide, and the use of antibiotics for acne is no exception. The more we use antibiotics, the more likely it is that bacteria will develop resistance to them. This means that over time, antibiotics may become less effective at treating acne and other bacterial infections.

In addition, using antibiotics for acne can contribute to antibiotic resistance in other areas of the body, making it harder to treat infections like pneumonia, meningitis, and urinary tract infections. This is why it’s important to use antibiotics judiciously and only when necessary.

Other side effects

In addition to the side effects mentioned above, antibiotics can have a range of other side effects. These can include:

– Headache
– Dizziness
– Fatigue
– Joint pain
– Muscle pain
– Rash
– Changes in taste

Some antibiotics can also affect the liver or kidneys, so it’s important to have regular blood tests while taking these medications.

Alternatives to antibiotics

Given the potential side effects of antibiotics, it’s worth considering alternative treatments for acne. These can include:

Topical treatments: Topical medications like benzoyl peroxide, salicylic acid, and retinoids can be effective at reducing acne without the risk of systemic side effects.

Birth control pills: Birth control pills can be effective at reducing acne in women by regulating hormones that contribute to acne.

Lifestyle changes: Eating a healthy diet, getting enough sleep, reducing stress, and avoiding picking or touching your skin can all help reduce the severity of acne.

In some cases, a combination of treatments may be necessary to effectively treat acne. Your healthcare provider can help you determine the best course of treatment for your individual needs.

In conclusion, while antibiotics can be effective at treating acne, they come with a range of potential side effects, from digestive upset to antibiotic resistance. If you’re considering antibiotics as a treatment for acne, it’s important to weigh the benefits against the risks and consider alternative treatments if possible. Always talk to your healthcare provider before starting any new medication, and report any side effects you experience. With the right treatment plan, you can reduce the severity of your acne and improve your skin health.
