¿Qué es Sildenafil Citrate ?

¿Cuánto tarda el sildenafil en empezar a hacer efecto? ▼

Para la disfunción eréctil, el sildenafil suele tomarse aproximadamente una hora antes de la actividad sexual, aunque puede tomarse entre 30 minutos y 4 horas antes. Tomarlo con una comida pesada o rica en grasas puede retrasar la rapidez con que actúa. Aun así, requiere estimulación sexual para producir efecto. Siga las indicaciones de quien le receta para su situación específica.

¿Cuál es la diferencia entre el sildenafil y Viagra? ▼

No hay diferencia en el ingrediente activo. Viagra es el nombre de marca original, y el citrato de sildenafil es la versión genérica del mismo medicamento. Como es un genérico, el citrato de sildenafil suele ser mucho menos costoso que Viagra de marca.

¿Puedo tomar sildenafil con medicamentos para la presión arterial? ▼

Depende del medicamento específico. El sildenafil nunca debe combinarse con nitratos (como la nitroglicerina o el isosorbida) ni con riociguat, porque esto puede causar una caída peligrosa de la presión arterial. También se necesita precaución con los alfabloqueantes y otros antihipertensivos. Informe a su médico y farmacéutico sobre todos los medicamentos que toma para que puedan verificar si hay interacciones antes de que empiece a tomar sildenafil.

¿Cuánto tiempo dura el sildenafil en el organismo? ▼

Los efectos del sildenafil para la disfunción eréctil generalmente duran alrededor de 4 a 6 horas, aunque esto varía de una persona a otra. Después, el medicamento se elimina gradualmente del cuerpo. Si una erección dura más de 4 horas, busque atención de emergencia, ya que esto puede ser una afección grave.

¿Cuál es la diferencia entre Viagra y Revatio si ambos son sildenafil? ▼

Ambos contienen el mismo ingrediente activo, el sildenafil, pero están aprobados por la FDA para usos diferentes y se dosifican de manera distinta. Viagra está aprobado para la disfunción eréctil en hombres adultos, mientras que Revatio está aprobado para la hipertensión arterial pulmonar en adultos y en niños de 1 año en adelante. Solo debe tomar el producto y la dosis que quien le receta le haya indicado para su afección.

¿Cuánto cuesta Sildenafil Citrate sin seguro? ▼

El precio de Sildenafil Citrate sin seguro varía según la farmacia, la dosis y la cantidad. Rx.com compara los precios en efectivo en más de 60,000 farmacias de EE. UU. para que encuentre el precio más bajo cerca de usted. Muchas personas ahorran hasta un 68% sobre los precios de lista con un cupón gratuito de Rx.com.

¿Existe una versión genérica de Sildenafil Citrate? ▼

Es posible que existan versiones genéricas de Sildenafil Citrate. Los genéricos contienen los mismos ingredientes activos que los medicamentos de marca y suelen costar entre un 80 y un 90 % menos. Busque Sildenafil Citrate en Rx.com para comparar los precios de las versiones genérica y de marca en farmacias cercanas.

¿Cuál es la farmacia más económica para Sildenafil Citrate? ▼

La farmacia más económica para Sildenafil Citrate depende de su ubicación y su dosis. Rx.com compara los precios en CVS, Walgreens, Walmart, Kroger, Costco y miles de farmacias independientes. Ingrese su código postal en Rx.com para encontrar el precio más bajo de Sildenafil Citrate cerca de usted.

¿Busca un cupón de citrato de sildenafil? El citrato de sildenafil es la versión genérica de bajo costo de Viagra y Revatio, y como ya está disponible como genérico, el precio en efectivo suele ser una fracción del de la marca. Pero los precios de una misma tableta pueden variar mucho de una farmacia a otra, así que vale la pena comparar. Ingrese su código postal arriba para ver el precio de hoy del citrato de sildenafil en más de 60,000 farmacias de EE. UU. y use la tarjeta de descuento gratuita de Rx.com al pagar, sin necesidad de seguro.

¿Qué es el citrato de sildenafil y cómo funciona?

El citrato de sildenafil es un inhibidor de la fosfodiesterasa tipo 5 (PDE5). Actúa potenciando el efecto del óxido nítrico, que relaja el músculo liso y dilata los vasos sanguíneos para mejorar el flujo de sangre. Es el ingrediente activo de varios productos de marca aprobados por la FDA, vendidos con los nombres de Viagra, Revatio y Liqrev.

Sus usos aprobados por la FDA dependen de la marca. Como Viagra, el sildenafil trata la disfunción eréctil (DE) en hombres adultos. Como Revatio y Liqrev, el sildenafil trata la hipertensión arterial pulmonar (HAP, Grupo I de la OMS) en adultos, y Revatio también está aprobado para niños de 1 año en adelante, para mejorar la capacidad de ejercicio y retrasar el empeoramiento clínico. El genérico, citrato de sildenafil, contiene el mismo ingrediente activo que estos medicamentos de marca.

Costo y ahorro del citrato de sildenafil sin seguro

Como el citrato de sildenafil está disponible como genérico, normalmente es mucho más económico que Viagra o Revatio de marca. Aun así, el precio en efectivo de la misma tableta y concentración puede diferir de manera significativa entre farmacias, por lo que comparar antes de surtir es importante. Ingrese su código postal arriba para ver el precio de hoy en farmacias cerca de usted e imprima o envíese por mensaje de texto la tarjeta de descuento gratuita de Rx.com, sin necesidad de seguro.

Si le recetan la marca y prefiere la propia oferta del fabricante, Viagra tiene una tarjeta de ahorro del fabricante en viagra.com/en/savings-card-download. Los requisitos y condiciones varían, así que revise los detalles en esa página. Para la mayoría de las personas, el citrato de sildenafil genérico es la opción más asequible.

Sildenafil frente a Viagra y otras alternativas

El citrato de sildenafil y Viagra contienen el mismo ingrediente activo; Viagra es simplemente el nombre de marca original, mientras que el citrato de sildenafil es el genérico. Revatio es otra marca de sildenafil, dosificada para la hipertensión arterial pulmonar en lugar de para la DE. Otros inhibidores de la PDE5 usados para la disfunción eréctil incluyen tadalafil (marca Cialis), vardenafil y avanafil.

Estos medicamentos se diferencian principalmente en la rapidez con que hacen efecto y en cuánto tiempo duran. Cuál se adapta mejor a usted es una conversación que debe tener con quien le receta. Sea cual sea el que le receten, compare su precio arriba antes de surtir.

Seguridad y advertencias importantes

El citrato de sildenafil no es una sustancia controlada y no lleva advertencia en recuadro, pero hay consideraciones de seguridad importantes. Nunca debe tomarse con medicamentos con nitratos (como la nitroglicerina o el isosorbida) ni con riociguat, porque la combinación puede causar una caída grave, potencialmente mortal, de la presión arterial. No lo combine con otros inhibidores de la PDE5 como el tadalafil. Tenga precaución con los alfabloqueantes y otros medicamentos para la presión arterial. Una erección que dura más de 4 horas (priapismo) es una emergencia médica.

Los efectos secundarios comunes incluyen dolor de cabeza, sofocos, congestión nasal, malestar estomacal y cambios temporales en el color o el brillo de la visión. Los eventos raros pero graves incluyen pérdida súbita de la visión (NAION), pérdida súbita de la audición y problemas cardiovasculares como ataque cardíaco o accidente cerebrovascular, especialmente en personas con enfermedad cardíaca preexistente. Esta es información general, no consejo médico; hable siempre con su médico o farmacéutico sobre su salud y los medicamentos que toma.
