What is doxycycline used for?

Doxycycline is a tetracycline antibiotic used for chlamydia and other susceptible bacterial infections. Testing and partner management remain part of safe STI care.

How is doxycycline taken?

For uncomplicated chlamydia, a commonly recommended course is 100 mg twice daily for seven days. The exact regimen follows the diagnosis and local guidance.

What side effects can doxycycline cause?

Nausea, indigestion, diarrhoea and sensitivity to sunlight can occur. Take it with plenty of water and remain upright afterwards to reduce oesophageal irritation.

What does the doctor check before prescribing doxycycline?

The clinician checks pregnancy or breastfeeding, age, liver problems, allergies and interactions with antacids, iron, retinoids and some anticoagulants.

Can I get a consultation for Doxycycline 100mg from Frankfurt?

Yes. Hi-Doctor runs 100 % online across the EU, so if you live in Frankfurt you can fill in the questionnaire and receive the medical review without travelling. The electronic prescription issued by the licensed doctor is valid in any EU pharmacy under Directive 2011/24/EU; outside Spain, the pharmacist dispenses the locally marketed equivalent of the same active ingredient.

Is my sexual health consultation fully confidential?

Yes. All communication happens in the private chat of your account, GDPR-compliant. The doctor treats discretion as a core of the service and there is no history visible outside your consultation.

What is the private electronic prescription and why is it valid across the EU?

The private electronic prescription (Receta Médica Privada Electrónica) is issued by a licensed doctor in Spain. It is a PDF carrying every field required by EU Directive 2011/24/EU (patient, prescriber with country of registration, active ingredient, dose), which makes it legally recognised across all 27 EU member states. In Spanish pharmacies it is dispensed from the QR; outside Spain, the pharmacist dispenses the locally marketed equivalent of the same active ingredient.

About

What is Doxycycline 100mg?

Active ingredient: Doxycycline · Dosages: 100 mg

Doxycycline is a tetracycline antibiotic and a preferred treatment for many uncomplicated chlamydia infections. A test, site of infection and pregnancy status can change the plan.

The indication, regimen and follow-up depend on your history and country guidance. A licensed doctor decides whether it is appropriate; prescribing is never automatic.

How it works in the body

It binds to bacterial ribosomes and blocks production of proteins the bacteria need to grow.

How it helps

What it can offer when appropriate.

Evidence-based first option

It is commonly recommended for uncomplicated chlamydia when no contraindication applies.

Covers infection sites

The clinician checks genital, rectal and throat exposure so testing and follow-up fit the case.

Partner advice included

Treatment is paired with advice on abstinence, partner notification and repeat testing when needed.

What to expect

A doctor-defined regimen.

A common uncomplicated-chlamydia regimen is 100 mg twice daily for seven days. The diagnosis and local guidance determine the final course.

Before treatment · Confirm testing and pregnancy status
Days 1–7 · Take the prescribed doses evenly
Afterwards · Follow partner and sexual-contact advice

Typical regimen

Common regimen100 mg twice daily
Common duration7 days

Your schedule is personal

These are typical steps only. Your doctor adjusts the plan to how you respond and tolerate it — and you can message them at any point.

Safety first

Safety, in full.

Doxycycline 100mg is an effective medicine — and like any medicine it carries risks. Your doctor screens for all of this before prescribing. Here's the honest picture, not just reassurance.

Bacterial infections, including genital chlamydia (usually 100 mg twice a day for 7 days).

Swallow each capsule with a full glass of water, sitting or standing upright, and stay upright for at least 30 minutes.
Take with food or milk to reduce nausea.
Complete the full 7 days even if symptoms disappear earlier.
Avoid sex until you have finished the course and any partner has been treated.

Who should not take it

Pregnant or breastfeeding women — doxycycline deposits in developing bones and permanently stains developing teeth.
Children under 12, for the same reason.
Allergy to doxycycline or any other tetracycline.

When to seek urgent care

For severe, sudden or unexpected symptoms, call your local emergency number or go to the nearest emergency department. Then let your doctor know through your account chat.
