Feverfew — lo que la monografía europea realmente respalda, para qué no es, la forma y cuánto tiempo está pensado usarse, efectos adversos y la 2 interacción medicamentosas documentada.
Esta es una página de referencia, no un diagnóstico ni una receta. Los productos herbales son farmacología real: tienen efectos, efectos adversos e interacciones. Diga a su médico y farmacéutico todo lo que toma, incluidos tés y suplementos, y nunca suspenda ni cambie un medicamento recetado por algo que lea aquí.
Qué es
Tanacetum parthenium (L.) Sch.Bip. — herb (Tanaceti parthenii herba)
Agrupado aquí bajo Joints, urinary tract and hormones. Posición regulatoria:Monografía herbal de la UE — uso tradicional.
Lo que respalda la evidencia
La indicación registrada:Prophylaxis of migraine headaches, after serious conditions have been excluded by a doctor.
The wording of feverfew's registration is the most instructive thing about it. It is a preventive taken daily over months, not something to swallow during an attack, and the indication explicitly requires that a doctor has first excluded serious causes of headache. The trial evidence is inconsistent: a Cochrane review of feverfew for preventing migraine found the evidence insufficient to establish an effect, with the better-conducted trials the least encouraging. Two practical details set it apart. Chewing fresh leaves, the old folk method, causes mouth ulcers and soreness in a substantial share of people. And stopping abruptly after months of use has been described as producing a rebound of headache, anxiety, stiffness and poor sleep — so if you stop, taper.
C — Traditional use only Plausible from thirty or more years of use, which is what a traditional-use registration means. No clinical evidence was required and none has settled it.
Para qué no es
Treating a migraine attack, and any new, sudden, severe or changed headache, headache with fever and a stiff neck, or headache after a head injury — those need urgent assessment.
Forma, potencia y cuánto tiempo
Dried leaf in capsules and tablets, sometimes standardised to parthenolide content, which varies widely between products. Fresh leaf chewing is the traditional method and the one that ulcerates mouths.
Duración.Prophylaxis is judged over months, not days. Taper rather than stop abruptly after long use.
Ninguna cifra en gramos aparece en esta página a propósito. La parte de la planta, el disolvente de extracción y la relación droga-extracto definen juntos una preparación, y un número tomado de una no describe otra. El razonamiento está en el hub; la cantidad que le aplica es la impresa en el envase que sostiene, y un farmacéutico la leerá con usted.
Efectos adversos
Mouth ulceration and tongue soreness from fresh leaf. Stomach upset, bloating. Allergic reactions in daisy-family (Asteraceae) sensitive people.
Quién debería evitarlo
Not in pregnancy — feverfew has traditional use as a uterine stimulant — and not while breastfeeding. Most registrations are for adults only.
Interacciones con medicamentos
| Medicamento o sustancia | Qué se describe |
|---|---|
| Anticoagulants and antiplatelets (warfarin, DOACs, aspirin, clopidogrel) | Feverfew appears on the bleeding-risk list. Evidence is limited to laboratory work and case reports, and the caution is standard rather than proven. |
| Anti-inflammatory painkillers (NSAIDs) | Regular anti-inflammatory painkillers are the other common ingredient in a migraine cupboard, and medication-overuse headache is a far more frequent cause of daily headache than most people taking them realise. |
