From the Guidelines
Doxycycline is a recommended treatment option for skin boils, particularly those caused by bacterial infections like Staphylococcus aureus, with a typical adult dosage of 100 mg taken orally twice daily for 7-10 days 1.
Treatment Considerations
When considering doxycycline for the treatment of skin boils, it's essential to note that incision and drainage is the primary treatment for cutaneous abscesses, including boils 1. Antibiotic therapy, such as doxycycline, may be recommended in addition to incision and drainage for certain conditions, including severe or extensive disease, rapid progression, signs and symptoms of systemic illness, associated comorbidities or immunosuppression, extremes of age, abscess in area difficult to drain, associated septic phlebitis, or lack of response to incision and drainage alone 1.
Dosage and Administration
The dosage of doxycycline for skin boils is typically 100 mg taken orally twice daily for 7-10 days for adults 1. For children over 8 years old, the dosage is usually 2-4 mg/kg/day divided into two doses 1. It's crucial to take the medication with a full glass of water and with food if stomach upset occurs.
Additional Measures
While using doxycycline, applying warm compresses to the boil for 10-15 minutes several times daily can help bring it to a head and promote drainage 1. However, do not attempt to squeeze or lance the boil yourself, as this can lead to further complications.
Potential Side Effects
Doxycycline can cause photosensitivity, so it's essential to protect your skin from sun exposure while taking it 1. Complete the full course of antibiotics even if the boil improves before the medication is finished. If the boil doesn't improve within 2-3 days, worsens, or you develop fever, seek medical attention as you may need incision and drainage or a different antibiotic.

From the Research
Boil Treatment with Doxycycline
- Doxycycline is an antibiotic that has been studied for its effectiveness in treating various infections, including skin and soft tissue infections 2.
- A study comparing doxycycline and cephalexin for the treatment of presumed streptococcal skin and soft tissue infection found that both antibiotics had a low rate of clinical failure, with no significant difference between the two groups 3.
- Doxycycline has been shown to be effective against a range of gram-positive and gram-negative aerobic and anaerobic pathogens, including those that cause skin and soft tissue infections 2.
- However, the use of doxycycline for boil treatment is not specifically addressed in the available evidence, and its effectiveness for this indication is not well established.
Comparison with Other Antibiotics
- A systematic review of interventions for bacterial folliculitis and boils found that comparative trials have not identified important differences in efficacy or safety outcomes between different oral antibiotics, including cefadroxil, flucloxacillin, azithromycin, and cefaclor 4.
- Another study compared cephalexin and dicloxacillin for the treatment of staphylococcal skin and skin structure infections, and found that both antibiotics were equally effective 5.
- Cephalexin has been shown to be effective in the treatment of streptococcal and staphylococcal skin infections, with cure rates of 90% or higher 6.
Limitations of the Evidence
- The available evidence does not provide a clear answer to the question of whether doxycycline is effective for boil treatment.
- Further studies are needed to establish the efficacy and safety of doxycycline for this indication.
- The use of doxycycline for boil treatment should be guided by clinical judgment and consideration of the individual patient's needs and circumstances.
