Chlamydia treatment 

What is chlamydia?

Chlamydia is the most commonly diagnosed sexually transmitted infection (STI) in the UK. It is caused by the bacterium Chlamydia trachomatis and is transmitted through unprotected vaginal, anal or oral sex, and through genital contact with an infected person. It can affect people of any age, though rates are highest among sexually active people under 25.

Most people with chlamydia experience no symptoms, which means the infection can go undetected and untreated for months or years. When left untreated, chlamydia can lead to serious complications including pelvic inflammatory disease (PID) in women, epididymitis in men, and in some cases reduced fertility.

Available treatment approaches

• Antibiotic treatment
• Testing and contact tracing support
• Foundations of sexual health

How the assessment process works

• Complete a short, secure medical questionnaire.
• Select a treatment category for assessment.
• An independent UK-registered prescriber reviews your information and determines whether medical treatment may be appropriate.
• Next steps are arranged following clinical approval.

Understanding chlamydia and treatment options

Chlamydia is a bacterial infection that can affect the genitals, rectum and throat. Because it so frequently presents without symptoms, routine testing is an important part of sexual health care, particularly for sexually active people under 25 or those with new or multiple partners.

When symptoms do occur, they may include unusual discharge, pain or burning when urinating, pain or swelling in the testicles, and in women, bleeding between periods or after sex. Rectal infections may cause discomfort or discharge.

Chlamydia is highly treatable with antibiotics when detected. Early treatment reduces the risk of complications and prevents onward transmission.

How chlamydia is diagnosed

Chlamydia is diagnosed through a simple test. In most cases, this involves a self-taken swab from the affected area (vagina, rectum or throat) or a urine sample. Testing is available free of charge through NHS sexual health clinics, some GP surgeries, and through home testing kits available from the NHS and some pharmacies.

When should chlamydia be treated?

Treatment should begin as soon as a positive test result is confirmed. Even if you have no symptoms, untreated chlamydia can cause long-term complications, including pelvic inflammatory disease, chronic pelvic pain, and in some cases reduced fertility in both men and women.

Sexual partners should be informed and tested as soon as possible. This is known as partner notification or contact tracing, and is an important part of preventing reinfection and further transmission.

Which healthcare professionals can support chlamydia treatment?

Depending on individual circumstances, different healthcare professionals may be involved in diagnosis and treatment.

General practitioner (GP)
Can diagnose and treat chlamydia and provide referrals to specialist sexual health services where needed.

Sexual health clinician
Specialist sexual health and GUM (genitourinary medicine) clinics offer confidential testing, treatment and contact tracing support without the need for a GP referral.

UK-registered online prescriber
A UK-registered prescriber can assess suitability for antibiotic treatment through a secure online process following a clinical questionnaire.

Public health nurse
May support contact tracing and partner notification, particularly in younger populations.

How is chlamydia managed?

Chlamydia is treated with a short course of antibiotics, which is effective in the large majority of cases when taken correctly and completed in full. Management typically involves the following steps.

• Antibiotic treatment: A course of antibiotics is prescribed following a confirmed positive test and clinical assessment.
• Partner notification: Sexual partners from the relevant period should be informed, tested and treated where appropriate.
• Avoiding sexual contact: During and immediately after treatment, sexual contact should be avoided to prevent reinfection or onward transmission.
• Follow-up testing: A repeat test is recommended approximately three months after treatment, particularly if there is a risk of reinfection.

Medicines that may be considered

Where clinically appropriate, a UK-registered prescriber may consider antibiotic treatment for confirmed or suspected chlamydia. Suitability depends on individual health profile, any antibiotic allergies, and current clinical guidance.

Doxycycline

Doxycycline is currently the first-line antibiotic recommended by the British Association for Sexual Health and HIV (BASHH) for the treatment of chlamydia. It is taken twice daily for seven days. It should not be taken during pregnancy.

Azithromycin

Azithromycin was previously the most commonly used first-line treatment and may still be considered in certain circumstances, including during pregnancy, where doxycycline is not appropriate. It is typically given as a single dose or a short course.

How DoktorABC UK supports access to care

DoktorABC UK is a digital health platform that connects patients with independent, UK-registered healthcare professionals. Patients can access a clinical assessment through a secure online process.

A UK-registered prescriber reviews the information you provide and determines whether treatment may be appropriate for you. If treatment is considered suitable, a prescription is issued by the UK-registered prescriber in accordance with UK regulations.

DoktorABC UK does not itself provide medical care, issue prescriptions or dispense medicines. All clinical decisions are made by the independent prescribing healthcare professional following an individual assessment.

Summary

Chlamydia is a common, treatable bacterial infection that often presents without symptoms. Early testing and prompt antibiotic treatment are the most effective ways to manage it, reduce the risk of complications, and prevent onward transmission. Partner notification is an important part of the process. A UK-registered prescriber can assess your individual circumstances and advise on the most appropriate course of treatment.
