STI Treatment in Canada
Sexually transmitted infections (STIs) are a significant public health concern in Canada, with rates of infections like chlamydia, gonorrhea, and syphilis rising in recent years.
Medications, Access, and Care
Fortunately, Canada's healthcare system provides robust, confidential, and often free access to testing, treatment, and care.
10+ years experience
The recommendations made by the Public Health Agency of Canada (PHAC) and the Canadian Guidelines on Sexually Transmitted Infections are the primary sources of inspiration for treatment guidelines in Canada. The following are basic treatments for sexually transmitted infections (STIs) caused by bacteria and parasites.
Privacy policy
This guide provides an in-depth look at STI treatment in Canada, focusing on the standard medications used, how to access them, and the importance of completing prescribed therapies.
The Canadian Healthcare Framework for STI Care
Canada operates on a system of universal publicly funded healthcare, meaning essential medical services are covered for Canadian citizens and permanent residents.
Testing
Each province and territory administers its own health insurance plan (e.g., OHIP in Ontario, MSP in British Columbia, RAMQ in Quebec).
The treatment of sexually transmitted infections (STIs) in Canada, covering the healthcare system, common infections, medications, and their application.
Prevalent STIs in Canada and Their Common Treatments
Testing: STI testing is fully covered by provincial health plans. You can get tested through:
Your family doctor
Walk-in clinics
Sexual health clinics: These are often the best option as they specialize in confidential, non-judgmental care and frequently offer faster testing times. Examples include Hassle Free Clinic in Toronto, BC Centre for Disease Control in Vancouver, and various CLSC clinics in Quebec.
Treatment: If a medication is administered by a doctor in a clinic or hospital (e.g., an injection), it is covered. Prescription medications dispensed at a pharmacy are typically not fully covered by basic provincial plans. This is where additional insurance comes into play.
Drug Coverage: Costs for prescription pills or creams are covered through:
Private insurance (through an employer or school).
Provincial drug benefit plans for specific groups like seniors, those on social assistance, or individuals with high drug costs relative to their income.
Paying out-of-pocket.
1. Chlamydia
Microorganism Chlamydia trachomatis is the root cause.
Azithromycin is the standard treatment here. One single dosage, taken orally, is one gram (one thousand milligrams). Due to the fact that it is both highly effective and convenient in that it only requires a single dose, this medication is the most often used form of treatment.
Doxycycline is an alternative treatment option. 100 milligrams should be taken orally twice daily for a period of seven days. However, you will need to remember to take tablets for a week in order to get the same level of success.
Important Notes: In order to prevent reinfection, partners who have been in the relationship for the past sixty days must be contacted, tested, and treated. It is not usually necessary to do a test-of-cure, which is a repeat test three to four weeks following therapy, although it may be advised in some circumstances.
2. Gonorrhea
Bacterium Neisseria gonorrhoeae is the root cause.
There is a huge problem with gonorrhea since it has gained resistance to a number of different medications. In order to fight this, rules and regulations in Canada are often modified.
Dual therapy is the standard treatment format. Ceftriaxone Injection: The foundation of therapy is a single intramuscular (IM) injection of 500 milligrams of ceftriaxone. It should be noted that the dosage can be altered according on the local resistance patterns and the individual's weight; the dosage was formerly 250 mg, but it has been raised. Oral Azithromycin: In the past, a single oral dose of one gram (1000 mg) of azithromycin was used in conjunction with Ceftriaxone in order to combat the possibility of co-infections and delay resistance. On the other hand, as a result of the increasing resistance to azithromycin, the PHAC now suggests Ceftriaxone 500 mg intramuscularly as monotherapy in many instances. Based on the most recent recommendations, the clinician will choose the most appropriate treatment plan.
The importance of follow-up cannot be overstated because of the rise in antibiotic resistance. Notification and treatment of partners are required. Testing for other sexually transmitted infections (STIs) is required, particularly for chlamydia, which is a frequent co-infection.
3. Syphilis
Trichomonas pallidum, a bacterium, is the cause.
The administration of penicillin G by injection is the treatment that is considered to be the gold standard for all stages of syphilis. Whether it is a primary, secondary, latent, or tertiary stage, the formulation and duration have different characteristics. In the early stages of syphilis (primary, secondary, and early latent), a single intramuscular (IM) injection of benzathine penicillin G containing 2.4 million units is administered. A total of 7.2 million units of benzathine penicillin G should be administered intramuscularly (IM) once per week for three weeks in a row for patients with late latent or tertiary syphilis.
In the case of patients who are allergic to penicillin, this is a very dangerous medical problem. It is common practice to choose desensitization to penicillin as the method of treatment. Alternatives such as Doxycycline, which should be taken orally twice daily for a period of 14 days for early syphilis and 28 days for late syphilis, may be utilized under the strict supervision of a specialist.
Important Remarks: In order to determine whether or not the therapy was successful, syphilis patients need to have thorough follow-up with blood tests at 3, 6, 12, and 24 months. Tracing and testing each and every partner is required.
4. Trichomoniasis
Trichomonas vaginalis, a parasite, is the root cause.
Metronidazole or Tinidazole may be used as the standard treatment. You should take either a single oral dose of 2 grams or 500 milligrams twice day for a period of seven days. A single dose of tinidazole, two grams, should be taken orally. When compared to metronidazole, it is often more well tolerated.
Note: It is extremely important to refrain from drinking alcohol while undergoing therapy and for a period of seventy-two hours after terminating treatment with metronidazole or tinidazole, as this might result in a serious adverse response (including nausea, vomiting, and flushing).
5. Management of Viral STIs vs. Treatment
Human Papillomavirus (HPV), Herpes Simplex Virus (HSV), and HIV are examples of sexually transmitted infections (STIs) that cannot be cured but can be adequately treated with treatment.
Treatment for HIV consists of antiretroviral therapy, sometimes known as ART, which is a mix of drugs used on a daily basis that suppress the virus to levels that are undetectable. The presence of an undetectable viral load indicates that the virus cannot be transmitted sexually (U=U), which in turn enables a life expectancy that is very close to normal. All of these medications are covered in their entirety by both provincial plans and federal programs.
Herpes simplex virus (HSV) is treated with antiviral medications such as acyclovir, valacyclovir, and famciclovir. You are able to take them: In the context of an epidemic, to reduce the length of time that it lasts. Suppressively: As a daily therapy to limit the frequency of breakouts and lower the danger of transmission to people who are in relationships with other people.
In the case of the Human Papillomavirus (HPV), there is currently no therapy available for the virus itself; however, the health issues that it causes can be addressed. To protect students from the most deadly strains, the vaccination (Gardasil®9) is widely available and free of charge in school programs across the country of Canada. Additionally, there are treatments available for pre-cancerous cervical alterations, such as the LEEP surgery, as well as for genital warts, such as cryotherapy and topical lotions.
6. A Practical Guide to Obtaining Medication
Get Tested: In order to receive an accurate diagnosis, you are required to see a medical practitioner. Self-diagnosis and the effort to utilize antibiotics that have been around for a long time is risky and contributes to the development of antibiotic resistance.
Be Sure to Get the Prescription: The physician will provide you with a prescription for the medication that you require.
Go to a Pharmacy: Bring the prescription to any pharmacy that is authorized to do business. If you are looking for advice on how to take the medication, potential adverse effects, and potentially harmful interactions, the pharmacist is a wonderful resource.
Pay for the Expenses: A copy of your private insurance card should be presented to the pharmacist if you have it. A deductible or a negligible portion of the total cost will most likely be required of you. You will be responsible for paying the entire charge if you do not have insurance. It is a good idea to inquire with the pharmacist or the physician about the availability of a generic version, as it is substantially less expensive. It is possible that certain sexual health clinics will offer free on-site administration of certain drugs, such as the injection for gonorrhea or syphilis.
7. Partner Notification: An Essential Public Health Practice
The obligation for treatment does not only fall on the person. The technique of partner notification, also known as contact tracking, is utilized by healthcare practitioners in Canada. A public health nurse will assist you in informing your former sexual partners that they may have been exposed to a sexually transmitted infection (STI) and should be tested. This is a confidential procedure that will be carried out. This is very necessary in order to break the chain of transmission and safeguard the health of the community.
The healthcare system in Canada offers readily available and efficient avenues for the detection and treatment of sexually transmitted infections (STIs). Although bacterial sexually transmitted infections (STIs) may typically be cured with the appropriate antibiotics, it is imperative that the whole course of treatment be completed and that partners be treated. Modern medicine has effective methods for the management and prevention of sexually transmitted infections (STIs) that are caused by viruses. The most crucial actions are to be tested on a regular basis, to have open talks with partners, and to seek expert medical treatment as soon as possible if you have any concerns. One of the most important aspects of your overall health is ensuring that your sexual health is protected.
Frequently Asked Questions
What is the underlying logic of how STI treatment is organized in Canada, and who pays for the injection at the clinic versus the pills from the pharmacy?
The logic of the Canadian healthcare system for STIs is built on the principle of accessibility and confidentiality to curb epidemics. The key distinction is between the medical service and the pharmaceutical drug.
Medical Service (Testing and Procedures): Fully covered by the provincial public health insurance plan (e.g., OHIP in Ontario, MSP in BC). This includes:
Doctor's consultations.
Laboratory tests (blood, swabs, urine).
Any procedures performed in the clinic. This means an antibiotic injection (e.g., Ceftriaxone for gonorrhea or Penicillin G for syphilis) administered by a nurse under a doctor's orders will cost you nothing.
Pharmaceutical Drugs (Prescription Medications): Pills, creams, or suspensions that you get from a pharmacy with a prescription are typically not covered by the basic provincial health plan. Their cost is covered through:
Private insurance (from an employer or school).
Provincial drug benefit plans for specific groups (e.g., seniors, low-income individuals).
Out-of-pocket payment. Therefore, the cost of a course of doxycycline or azithromycin is usually paid by the patient if they lack private insurance.
Thus, the system aims to remove financial barriers at the diagnosis and critical treatment stage but shares the cost burden with the patient or their private insurer at the medication stage.
Why is a single shot of Prednisolone now often used alone to treat gonorrhea in France, instead of the previous combination "shot + pill" therapy?
This protocol change (from dual therapy to monotherapy) is a direct response to the global threat of antimicrobial resistance.
The Reason: The bacterium Neisseria gonorrhoeae has demonstrated a frightening ability to develop resistance to antibiotics. The previous standard was a combination of Ceftriaxone (shot) and Azithromycin (pill). This was done to attack the bacteria with two different mechanisms, lowering the chance of resistant strains surviving.
The Problem: In recent years, resistance of gonorrhea to Azithromycin has surged worldwide, including in Canada. Using a drug that is losing effectiveness became not only pointless but dangerous: it promotes the selection of even more resistant superbugs.
The Solution: The Public Health Agency of Canada (PHAC) updated its guidelines, making a higher dose of Ceftriaxone (500 mg IM) the first-line treatment as monotherapy. This helps preserve its effectiveness by removing the failing component from the regimen. The final decision on the treatment protocol is always made by a physician based on the latest official guidelines and local resistance data.
What are the options for a person with a penicillin allergy who is diagnosed with syphilis?
This is a complex clinical situation that requires a specialized approach and supervision by an infectious disease specialist. Standard alternatives are not as reliable.
The Gold Standard - Desensitization: The most preferred option is penicillin desensitization. This procedure is performed in a hospital under close medical supervision. The patient is given gradually increasing doses of penicillin to "train" their immune system to tolerate it temporarily. After successful desensitization, a full course of Benzathine penicillin G injections can be administered safely. This is crucial as penicillin is the only truly reliable drug to cure syphilis, especially in its late stages and neurosyphilis.
Alternatives (with caveats): If desensitization is not possible, Doxycycline (100 mg orally twice daily for 14 days) may be considered for early syphilis only. However, this regimen:
Is not suitable for pregnant women.
Is not effective for treating late latent or tertiary syphilis, including neurosyphilis.
Requires even more rigorous and long-term serological follow-up after treatment.
Is considered less reliable than penicillin.
The decision is always made by a specialist, weighing the stage of the disease, risks, and the patient's circumstances.
How is the process of partner notification organized in Canada, and why is it a cornerstone of public health?
Partner Notification is a confidential process vital for breaking the chain of STI transmission. It is typically handled in two main ways:
Patient Referral: A healthcare provider counsels the patient on how to inform their past partners themselves that they may have been exposed and should seek testing and treatment. They provide advice on how to do this anonymously.
Provider Referral: This is a more formal and anonymous process. The patient provides the contact information of their partners to a public health nurse. The nurse then contacts these individuals, informs them they have been exposed to an STI (without revealing the source patient's name), and strongly advises them to get tested and treated at a confidential clinic, often for free.
Its Importance: This practice breaks the chain of transmission. Treating one person is futile if their partners, who may be asymptomatic carriers, continue to spread the disease. It is a collective measure that protects not only individuals but also community health by slowing the rise of antibiotic resistance and overall infection rates.
What is the key philosophical difference in the Canadian system's approach to treating bacterial (e.g., chlamydia) versus viral (e.g., HIV, herpes) infections?
The difference is fundamental and lies in the contrast between the concepts of "cure" and "management or control."
Goal: Complete eradication of the pathogen from the patient's body.
Method: A short, targeted course of antibiotics (a single dose or a 1-2 week course). With correct treatment, the infection is completely and permanently cured.
Focus: A rapid and definitive solution.
Viral Infections (HIV, Herpes, HPV):
Goal:Suppression of the virus, control of its replication, and prevention of complications. Complete elimination of the virus is not yet possible with modern medicine.
Method:Long-term, often lifelong, suppressive therapy.
For HIV, this is a combination of antiretroviral drugs (ART) taken daily to reduce the viral load to an undetectable level.
For herpes, daily antiviral medication (e.g., valacyclovir) is used to suppress outbreaks and reduce transmission risk.
Focus: Transforming an incurable infection into a chronic but manageable condition, allowing for a full life and protecting partners (e.g., the U=U principle for HIV).
