What is sildenafil?
Sildenafil is a medication used to improve erections. It works by expanding the blood vessels that go to the penis and delivering better blood flow. That in turn leads to better erections.
Sildenafil is the generic version of Viagra. The two medications are identical, with sildenafil being a cheaper and more available option.
Dosage of sildenafil depends on the severity of your ED. Talk to a doctor today and get a personalized care plan for your ED.

How to take sildenafil
Always take sildenafil as instructed by your doctor. Typically, you’ll want to take sildenafil about 1 hour prior to having sex. Take your dosage—specified by your doctor—on an empty stomach if possible. If you take it after a meal, it will take longer for the medication to start working. You will not get an erection just from taking the pill—sexual stimulation is required.

Side effects of sildenafil
Side effects with sildenafil are not common. When they do occur, they may include flushing, headaches, upset stomach, dizziness, and, in rare cases, vision changes.
If you experience persistent or worsening side effects, you should stop taking the medication and check in with your doctor.
Very rarely, sildenafil may lead to painful erection that lasts longer than 3-4 hours or does not go away. That is considered a medical emergency and you must seek medical help (go to the ER) immediately.

Affordable, accessible, and fastRead more Read less
I have many health issues and no health insurance, so I frequently need urgent care. K Health has been my favorite online service so far because you don’t have to do a phone call or video call – it is all text based. As someone with social anxiety this is a wonderful feature. I have used the service twice now and both times I have been helped quickly and efficiently. I recommend this to anyone who needs quick urgent care for a minor illness.Stormy R. | Jun 11 2022
Gave me my life backRead more Read less
I can not afford insurance, so I could not afford to see a doctor about my anxiety and panic attacks before finding K Health. I literally hid at home all the time and had massive panic attacks resulting in trips to the ER over basic stuff like grocery shopping. Now I actually look forward to getting out. I’ve developed hobbies that have turned into a home business and actually made a few friends. K Health literally saved me from myself. Thank you!!!Heather C. | May 24 2022
