Treatment Overview
Discovering painful sores or ulcers in the genital area can be a deeply distressing and frightening experience. Chancroid is a bacterial sexually transmitted infection (STI) that causes soft, painful ulcers and often leads to swollen lymph nodes in the groin. The physical discomfort can make walking or sitting difficult, while the emotional toll of an STI diagnosis can create anxiety and embarrassment. It is important to know that chancroid is a fully curable condition, and with prompt medical attention, the infection can be resolved quickly.
Treatment is essential not only to relieve the intense pain and heal the ulcers but also to prevent the transmission of the bacteria to sexual partners. Successful treatment also stops the formation of painful abscesses in the lymph nodes, known as buboes. Because the infection is bacterial, it does not go away on its own without specific medication. Treatment plans are generally straightforward, though doctors must consider factors such as pregnancy, allergies, and coinfection with other STIs when selecting the appropriate drug (Centers for Disease Control and Prevention, 2021).
Overview of treatment options for Chancroid
The primary and most effective approach to treating chancroid is the use of antibiotics. The goal is to kill the Haemophilus ducreyi bacteria responsible for the infection. Unlike viral STIs that must be managed long-term, chancroid can be cured completely.
Medical treatment focuses on clearing the infection rapidly to allow the skin to heal. For most patients, this involves a short course or even a single dose of medication. While large, swollen lymph nodes may sometimes require a doctor to drain fluid to relieve pressure, the core of the treatment is strictly pharmacological. Lifestyle changes, primarily sexual abstinence during treatment, are necessary to prevent spreading the infection, but they do not treat the bacteria itself.
Medications used for Chancroid
Antibiotics are the standard of care for chancroid. There are four main antibiotics typically used, falling into three distinct drug classes.
The first-line choices often include macrolide antibiotics, such as azithromycin. This is frequently preferred because it can often be given as a single oral dose, ensuring compliance. Another common first-line option is ceftriaxone, a cephalosporin antibiotic administered via a single injection.
Alternative treatments include fluoroquinolones, such as ciprofloxacin, or a multi-day course of erythromycin base (another macrolide). These are effective but may require taking pills for several days.
Patients can generally expect symptoms to improve within three days of starting treatment. Clinical experience suggests that the ulcers typically resolve completely within seven days, although large ulcers may take up to two weeks to heal. If lymph nodes are swollen, they may remain tender and swollen for weeks even after the infection is cured. Doctors typically require a follow-up visit to ensure the ulcers are healing properly (Mayo Clinic, 2022).
How these medications work
Each class of antibiotic attacks the Haemophilus ducreyi bacteria in a different way to stop the infection.
Cephalosporins, like ceftriaxone, work by disrupting the construction of the bacterial cell wall. Without a strong wall, the bacteria become unstable and burst, effectively killing them.
Macrolides (e.g., azithromycin, erythromycin) inhibit protein synthesis by binding to bacteria, preventing necessary protein production for growth and survival.
Fluoroquinolones (e.g., ciprofloxacin) target bacterial DNA, blocking enzymes required for DNA replication and reproduction. By stopping bacterial proliferation or survival, these drugs enable the immune system to clear the infection and promote healing (National Library of Medicine, 2020).
Side effects and safety considerations
While these antibiotics are generally safe, they have specific profiles that patients must be aware of. Common side effects include nausea, diarrhea, and stomach upset; ceftriaxone may cause temporary injection site pain.
Ciprofloxacin and other fluoroquinolones are generally avoided in pregnant or lactating women due to potential risk; cephalosporins or macrolides are safer alternatives.
Patients must be aware of drug allergies, especially if they have a penicillin reaction (related to cephalosporins). Testing for other STIs (e.g., HIV, syphilis) is vital due to common coinfection. Unhealing ulcers after seven days require medical attention, suggesting resistance or an alternate diagnosis.
Since everyone’s experience with the condition and its treatments can vary, working closely with a qualified healthcare provider helps ensure safe and effective care.
