Chlamydia: a 7-day course
With a positive test or a diagnosed partner, the doctor prescribes the standard European course: usually doxycycline for seven days, or azithromycin if you cannot take it or are pregnant.
Partner diagnosed? You can be treated too
If a recent partner has tested positive for chlamydia, European guidance is to treat you as well without waiting for your own result — the questionnaire asks exactly this.
What needs a clinic instead
Gonorrhoea and syphilis are treated with an injection, and any STI with pelvic pain, fever or testicular pain needs an examination. The doctor tells you where, and the €34 is refunded in full.

What is the treatment for chlamydia?
Chlamydia is treated with doxycycline 100 mg twice a day for seven days, or azithromycin where doxycycline cannot be taken, prescribed by a doctor after a positive test. No sex until seven days after both partners have finished, every partner from the last six months tested and treated, and a repeat test three to six months later, because reinfection is common.
How to get chlamydia or STD treatment online — what happens after you press start
1. The questionnaire — about 3 minutes
It asks whether you have been tested and what the result was, whether a recent partner has been diagnosed or is being treated, whether a doctor or clinic advised treatment, and whether you have had the same infection before. It then covers your symptoms — burning, discharge, blisters or ulcers, fever, pelvic or testicular pain — other conditions, allergies, pregnancy or breastfeeding, and the medicines you take.
2. The doctor's review
The doctor reads it personally. With a positive result or a diagnosed partner, the doctor prescribes the guideline course for that infection and tells you how long to avoid sex and when to retest. Symptoms without a result, or anything suggesting gonorrhoea, syphilis, pelvic inflammatory disease or a first herpes episode, are switched to a video consultation, where the doctor arranges testing or directs you to a clinic.
3. The pharmacy
The prescription appears in your Mobi Doctor profile in English, naming the active ingredient, so a pharmacy you choose in any of the 14 EU countries can dispense it. You pay the pharmacy for the medicine; Mobi Doctor does not sell or dispense medicines.
Symptoms but no test yet, pain in the pelvis or testicles, fever, a rash or an ulcer, or a possible HIV exposure? Book a video consultation instead — and for HIV exposure in the last 72 hours go to an emergency department today.
Right for the Express Assessment if

Chlamydia treatment online: which tablets, and for how long
Chlamydia is the most commonly reported bacterial STI in Europe and most infections cause no symptoms, which is why it is usually found by a test rather than by how you feel. The European guideline's first-line treatment is doxycycline 100 mg twice a day for seven days. Azithromycin — 1 g on the first day then 500 mg daily for two more days — is the alternative when doxycycline is unsuitable, and the choice in pregnancy, where doxycycline must not be used. Doxycycline is taken with food and a full glass of water, and makes skin burn faster in the sun. Either antibiotic is prescribed by the doctor from your questionnaire when the diagnosis is in hand. Do not have sex, even with a condom, until seven days after you and your partner have both completed treatment.
A test of cure is not needed after chlamydia unless you are pregnant or symptoms persist — but a repeat test three to six months later is recommended, because reinfection from an untreated partner is common. Every partner from the last six months should be told, tested and treated.
STD medication online: what an online doctor can and cannot prescribe
Trichomoniasis is treated with metronidazole, 400–500 mg twice daily for five to seven days — the preferred course for women, as the single 2 g dose fails more often — or that single dose where a course is impractical, with no alcohol during the course and for 48 hours after; the partner is treated at the same time. Recurrent genital herpes is treated with aciclovir, valaciclovir or famciclovir; a short course of one to five days works best when started within 24 hours of the first tingling. For six or more outbreaks a year the doctor can prescribe daily suppressive treatment, which cuts outbreaks and transmission.
Gonorrhoea is now treated with a single ceftriaxone injection given at a clinic, because resistance has made tablets alone unreliable; a test of cure follows. Syphilis needs benzathine penicillin by injection and staged follow-up blood tests. HIV needs specialist care, and a possible exposure in the last 72 hours is an emergency — post-exposure prophylaxis must start within that window. None of these can be handled from a questionnaire, and the doctor says so plainly and points you to the right service.
Where to get chlamydia treatment when you are abroad
A test done in Spain, Germany or the Netherlands is valid evidence wherever you are now. The questionnaire asks for the result and when it was taken; the doctor prescribes, and the prescription — in English, naming the active ingredient — can be dispensed at a pharmacy you choose in any of the 14 EU countries Mobi Doctor covers. Doxycycline, azithromycin and metronidazole are stocked by ordinary community pharmacies across the EU, so supply is not usually the problem. If you need a test rather than treatment, the doctor's video consultation can tell you where the nearest laboratory or sexual-health service is in the country you are in.
Herpes treatment online: episodic and suppressive prescriptions for recurrent genital herpes
For someone with diagnosed genital herpes, the value of an online prescription is speed: episodic treatment works best if started at the first sign of an outbreak, so having the tablets at home matters. The European guideline options for recurrences include aciclovir 800 mg three times daily for two days, valaciclovir 500 mg twice daily for three days, and famciclovir 1 g twice daily for one day. For frequent recurrences, daily suppressive treatment — aciclovir 400 mg twice daily or valaciclovir 500 mg once daily — is reviewed after a year. A first episode is different: it can be severe, needs a five-to-ten-day course, and is better assessed by a doctor who can see it, so it goes to the video consultation.
Using the prescription at a pharmacy anywhere in the EU
The prescription is issued in English by an EU-registered doctor, names the active ingredient rather than a brand, and carries a verification code the pharmacist can check at mobidoctor.eu/verify. A prescription issued in one EU country must be recognised in another (Directive 2011/24/EU); the active-ingredient name is what makes that work at the counter. Dispensing is the pharmacist's decision under the rules of the country you are in, and depends on the medicine being available there. The other conditions the Express Assessment covers — 13 in all, plus repeat prescriptions — are listed on the online doctor prescription page.
What Are Sexually Transmitted Diseases?
Sexually transmitted diseases (STDs) are infections that spread through sexual contact. They can be caused by bacteria, viruses, or parasites and pass from one person to another through body fluids like blood, semen, or vaginal fluids. STDs are common and can affect anyone who is sexually active. Some examples of STDs include chlamydia, gonorrhoea, syphilis, and genital herpes.
Many people with STDs don’t notice any symptoms, so it’s possible to have an STD without knowing it. This makes regular testing essential to help detect and treat infections early. If left untreated, STDs can cause serious health problems, but with proper care, many can be cured or managed.
Symptoms of Sexually Transmitted Diseases
The symptoms of sexually transmitted diseases (STDs) can be different for each person, and some people may not have any symptoms at all. This makes regular testing vital if you are sexually active. However, when symptoms do appear, they can affect different parts of the body and can range from mild to severe.
A common sign of an STD is pain or discomfort when you pee or during sex. You might also notice unusual discharge from the penis or vagina, which could look or smell different from normal. Another common symptom is the appearance of sores, bumps, or rashes around the genitals, anus, mouth, or thighs. These could be small, painless spots or more painful sores.
For men, painful or swollen testicles can be a sign of an STD. For women, unexpected bleeding between periods or after sex can also be a symptom. Some people might feel itching in or around the genital area.
As STDs get worse, more serious symptoms can show up. These can include a fever, tiredness, or pain in the lower stomach or pelvic area. Swollen lymph nodes, especially in the groin, are common with certain infections. Other symptoms like nausea, vomiting, or diarrhoea can happen as well.
In some cases, if the STD is not treated, it can lead to more serious problems, like memory loss, vision or hearing changes, or weight loss. These are signs that the infection has spread and needs immediate medical attention.
Remember, not all STDs show symptoms right away. Some infections can stay hidden for a long time before any signs appear. This is why regular testing is important to detect infections early and prevent more serious health problems.
Causes of Sexually Transmitted Diseases
Sexually transmitted diseases (STDs) result from infections that are transmitted between individuals through sexual contact. These infections can be transmitted through bodily fluids such as semen, blood, vaginal fluids, and occasionally saliva. The microorganisms responsible for STDs come in various types: bacteria, viruses, and parasites.
Bacterial infections, such as chlamydia, gonorrhoea, and syphilis, are common causes of STDs. These bacteria can be passed through unprotected sex but are usually treatable with antibiotics. Viral infections, like HIV, genital herpes, and HPV (human papillomavirus), are also common. Unlike bacterial infections, viral STDs can’t be cured, but treatments can help manage them. Parasites, like the one that causes trichomoniasis, are another cause of STDs and can spread through sexual contact.
Even though most STDs are spread through sexual activities, some can be passed through skin contact. For example, infections like genital herpes or HPV can be transmitted even if there are no visible symptoms. Blood-borne infections such as hepatitis B and HIV can occasionally be passed by shared razors or needles; STDs are not caught from towels or toilet seats.
Certain habits can increase your risk of getting an STD. These include having multiple sexual partners, not using condoms during sex, or sharing needles. If you’ve had an STD before, you’re also at a higher risk of getting one again if you don’t protect yourself.
It’s essential to take care of your sexual health. Some infections may go away on their own or be treated before they cause harm. But if left untreated, they can cause severe damage to your body. Practising safe sex and getting regular check-ups can help prevent the spread of STDs and protect your health.
In short, STDs are caused by bacteria, viruses, and parasites that spread through sexual contact or close contact with infected items. Being careful and staying informed can help you avoid getting or spreading these infections.
Types of STDs
Sexually transmitted diseases (STDs) are infections that spread through sexual contact. Bacteria, viruses, or parasites can cause them. Here are some common types of STDs and what you should know about them:
Chlamydia
Bacteria cause chlamydia, which is one of the most common STDs. Many people don’t have symptoms, but it can cause pain when peeing or unusual discharge from the penis or vagina. If untreated, it can cause serious problems like infertility in women.
Gonorrhoea
Gonorrhoea is another bacterial STD that can cause pain during urination and unusual discharge. It can affect different body parts, including the throat and reproductive organs. If it’s not treated, it can lead to more serious health problems like infertility in women.
Human Papillomavirus (HPV)
HPV is a virus that can cause genital warts. Some types of HPV are more dangerous because they can lead to cancer, such as cervical cancer. Luckily, there is a vaccine that protects against the harmful types of HPV.
Genital Herpes
Genital herpes is caused by the herpes simplex virus (HSV). It leads to painful sores or blisters on the genitals, anus, or mouth. There is no cure for herpes, but medication can help manage the symptoms.
Trichomoniasis
Trichomoniasis, also called "trich," is caused by a tiny parasite. In women, it can cause itching, burning, and unusual discharge. In men, it may cause irritation or burning when peeing. It can be easily treated with medication.
In summary, STDs are infections that can affect your health differently. Some, like chlamydia and gonorrhoea, can be cured with medicine if treated early. Others, like HIV and herpes, can't be cured but can be managed. The best way to protect yourself is by practising safe sex and getting regular check-ups.
