WARNING: RISK OF THYROID C-CELL TUMORS
- In rats, tirzepatide causes dose-dependent and treatment-duration-dependent thyroid C-cell tumors at clinically relevant exposures. It is unknown whether ZEPBOUND causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans as human relevance of tirzepatide-induced rodent thyroid C-cell tumors has not been determined. ZEPBOUND is contraindicated in patients with a personal or family history of MTC or in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). Counsel patients regarding the potential risk for MTC with the use of ZEPBOUND and inform them of symptoms of thyroid tumors (e.g., a mass in the neck, dysphagia, dyspnea, persistent hoarseness).

- ZEPBOUND is contraindicated in patients with: A personal or family history of MTC or in patients with MEN 2.
- Known serious hypersensitivity to tirzepatide or any of the excipients in ZEPBOUND.
- Serious hypersensitivity reactions, including anaphylaxis and angioedema, have been reported with tirzepatide.
- Personal or family history of medullary thyroid carcinoma or in patients with Multiple Endocrine Neoplasia syndrome type 2 Known serious hypersensitivity to tirzepatide or any of the excipients in ZEPBOUND
- Interacciones
- ZEPBOUND delays gastric emptying and has the potential to impact the absorption of concomitantly administered oral medications.
- Advertencias y precauciones
- Severe Gastrointestinal Adverse Reactions: Use has been associated with gastrointestinal adverse reactions, sometimes severe. ZEPBOUND is not recommended in patients with severe gastroparesis.
- Acute Kidney Injury Due to Volume Depletion: Monitor renal function in patients reporting adverse reactions that could lead to volume depletion.
- Acute Gallbladder Disease: Has been reported in clinical trials. If cholecystitis is suspected, gallbladder studies and clinical follow-up are indicated.
- Acute Pancreatitis: Has been observed in patients treated with GLP-1 receptor agonists, or ZEPBOUND. Discontinue if pancreatitis is suspected.
- Hypersensitivity Reactions: Serious hypersensitivity reactions (e.g., anaphylaxis, angioedema) have been reported postmarketing with tirzepatide. If suspected, advise patients to promptly seek medical attention and discontinue ZEPBOUND.
- Hypoglycemia: Concomitant use with insulin or an insulin secretagogue may increase the risk of hypoglycemia, including severe hypoglycemia. Reducing dose of insulin or insulin secretagogue may be necessary. Inform all patients of the risk of hypoglycemia and educate them on the signs and symptoms of hypoglycemia.
- Diabetic Retinopathy Complications in Patients with Type 2 Diabetes Mellitus: Has not been studied in patients with non-proliferative diabetic retinopathy requiring acute therapy, proliferative diabetic retinopathy, or diabetic macular edema. Monitor patients with a history of diabetic retinopathy for progression.
- Pulmonary Aspiration During General Anesthesia or Deep Sedation: Has been reported in patients receiving GLP-1 receptor agonists undergoing elective surgeries or procedures. Instruct patients to inform healthcare providers of any planned surgeries or procedures.
- Efectos adversos frecuentes
- most common adverse reactions, reported in ≥5% of patients treated with ZEPBOUND are: nausea, diarrhea, vomiting, constipation, abdominal pain, dyspepsia, injection site reactions, fatigue, hypersensitivity reactions, eructation, hair loss, gastroesophageal reflux disease.
- Embarazo
- Pregnancy Exposure Registry There will be a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to ZEPBOUND (tirzepatide) during pregnancy. Pregnant patients exposed to ZEPBOUND and healthcare providers are encouraged to contact Eli Lilly and Company at 1-800-LillyRx (1-800-545-5979). Risk Summary Weight loss offers no benefit to a pregnant patient and may cause fetal harm.
- Mecanismo de acción
- Tirzepatide is a GIP receptor and GLP-1 receptor agonist. It contains a C20 fatty diacid that enables albumin binding and prolongs the half-life. Tirzepatide selectively binds to and activates both the GIP and GLP-1 receptors, the targets for native GIP and GLP-1.

Cómo funciona
La tirzepatida actúa sobre el receptor en el que actúa la semaglutida y además sobre un segundo. Ambos son receptores de hormonas que el intestino libera cuando llega la comida, y el efecto práctico es del mismo tipo: vaciado gástrico más lento, saciedad más temprana, menos apetito. Si actuar sobre dos receptores en lugar de uno produce un resultado distinto es una pregunta que las fichas no responden, y esta página tampoco.
Original y genérico
No existe genérico y no podrá existir hasta que expiren las patentes. En Europa la marca Mounjaro lleva, bajo una única autorización europea, tanto la indicación de diabetes como la de control del peso, una diferencia con Estados Unidos que conviene conocer al leer fuentes americanas.
Cuánto cuesta
Precio mensual comparable al de la semaglutida, con el mismo panorama de financiación: cubierta bajo condiciones en algunos países y enteramente privada en otros.
Cómo conseguirlo legalmente
Requiere receta y se inyecta una vez por semana. En Europa una clínica online puede recetarla legítimamente, y la consulta debería trabajar con cifras reales y no con una casilla marcada: la ficha indica los umbrales de índice de masa corporal que hacen apropiada la prescripción.

- Embarazo
- Available data with MOUNJARO use in pregnant women are insufficient to evaluate for a drug-related risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy (see Clinical Considerations). Based on animal reproduction studies, there may be risks to the fetus from exposure to tirzepatide during pregnancy.

Preguntas
- ¿La tirzepatida es mejor que la semaglutida?
- Ninguna de las dos fichas hace una afirmación comparativa, y la postura honesta es que compararlas es un juicio clínico y no algo que una página de consulta pueda zanjar.
- ¿Por qué en Europa se usa un solo nombre para ambos usos?
- Porque la autorización europea cubre las dos indicaciones bajo el nombre Mounjaro, mientras que Estados Unidos las autorizó por separado con dos nombres. La sustancia es la misma en ambos casos.
- ¿De qué trata la advertencia recuadrada?
- De tumores tiroideos observados en estudios con animales, y figura íntegra en el apartado de la ficha, más arriba. Es también la razón por la que las contraindicaciones citan antecedentes familiares concretos.
