Sildenafil explained

Sildenafil is an active ingredient of Viagra and similar medication used to treat erectile dysfunction. According to NHS, It is effective, but it does require a prescription to use. Medication containing sildenafil comes in various forms including chewable tablets, tablets to be swallowed, and a liquid you drink.

Takbok #meerhoring does not contain sildenafil and requires no prescription, making it a very safe alternative for many men. Scroll down to read why.


In this article we dive into the details of sildenafil and offer alternative suggestions if you cannot, or don't want to, use products containing sildenafil.

How does sildenafil work

From NHS: Sildenafil belongs to a group of medicines called phosphodiesterase 5 (PDE5) inhibitors.

It temporarily increases blood flow to the penis when aroused, to help you get and maintain an erection. It typically takes 30-60 minutes to work. Like Takbok capsules, it requires stimulation to work.

Who can take sildenafil

Typically, men over 18 can take sildenafil. However, there are many men that cannot take it - and it doesn't play well with some medications. Anyone with a prescription can take it, because a medical doctor has cleared them to use it. You cannot buy it off a shelf or over the counter.

Who cannot take sildenafil

Because of the side effects and interaction with other medications, sildenafil must always be prescribed by a medical doctor. No one can get the product without a prescription.

Sildenafil is not safe to use for:

  • men suffering from low blood pressure
  • men with heart problems
  • men that recently suffered from a stroke or heart attack

Common side effects of sildenafil

Some listed common side effects include (from NHS):

  • headaches
  • feeling sick
  • hot flushes, including facial flushing
  • indigestion
