Proceso sencillo

From pre-check to pharmacy, step by step

Tirzepatide requires an individual assessment. This process checks the basic criteria first and supports a safer route to treatment.

Pre-test

Check the initial criteria before booking.

Book

Choose the available appointment time that suits you.

Medical consultation and prescription

Speak to the doctor and receive a REMPe prescription when appropriate.

Pharmacy

Take the prescription to an authorised pharmacy.

Initial guidance

Complete the pre-check first

The pre-check reviews basic age, BMI and safety criteria before booking. If minimum criteria are not met, tirzepatide will not be prescribed: consultation never guarantees a prescription and the final decision is always clinical.

Frequently asked questions

Questions about tirzepatide

Clear answers about prescriptions, safety, follow-up and availability in Spain.

What is tirzepatide?

It is a dual GIP and GLP-1 receptor agonist. The specific indication depends on the clinical circumstances and authorised product information.

Do I need a prescription for tirzepatide?

Yes. Tirzepatide requires a prescription. A consultation does not guarantee one: the doctor decides according to clinical indication and safety.

What is the difference between semaglutide and tirzepatide?

They are different active ingredients. Semaglutide acts on the GLP-1 receptor; tirzepatide acts on GIP and GLP-1. Choosing between them requires assessment of medical history, tolerance, current medicines and goals.

How much weight could I lose?

Results are not guaranteed. Response varies with the indicated treatment, tolerated dose, time, nutrition, activity and each patient’s medical circumstances.

How long does treatment continue?

Treatment duration is individual. The doctor reviews effectiveness, tolerance and safety before continuing, adjusting or changing the plan.

What are the most common side effects?

Nausea, diarrhoea, constipation, vomiting or abdominal discomfort may occur, especially when starting or increasing the dose. Severe or persistent symptoms require medical assessment.

When should I seek urgent care?

Seek urgent care for severe persistent abdominal pain, repeated vomiting that prevents hydration, an allergic reaction, breathing difficulty or significant deterioration.

Does the consultation include the medicine?

No. The online consultation costs 39€; if prescribed, the medicine is paid for separately at the pharmacy.

Do all pharmacies have the same price and stock?

Price depends on the presentation and applicable rules, and stock varies by pharmacy. A prescription does not reserve stock; confirm availability and price with an authorised pharmacy.

Can I buy tirzepatide online without a prescription?

No. Prescription-only medicines cannot legally be sold online in Spain. Use an authorised pharmacy and avoid unregulated offers.

Can I switch from Wegovy to Mounjaro?

Do not switch treatment by yourself. A doctor must review the indication, previous dose, tolerance and appropriate timing to reduce risk.

Can the consultation be by telephone or video?

Yes. The initial assessment can be completed remotely. If examination or tests are needed, the doctor will explain the next step.
