The summary

Androskat is an injection drug that is used for erection problems when erection pills do not help enough. The treatment works quickly, but involves risks and complexity of use. Fellos recommends safe and effective alternatives such as sildenafil and tadalafil, which are easy to use.

What is Androskat?

Androskat is a combination of medications that are given by injection into the penis. The medicine causes the blood vessels to dilate, causing an erection. This happens independently of sexual stimulation, so you can get an erection even without sexual stimulation. The active substances in Androskat stimulate blood flow to the cavernous body of the penis, leading to an erection.

This treatment is usually used as other methods — such as erection pills — do not give sufficient results. Because it is an injection, it is important that you learn the technique properly. This is because incorrect use can cause complications.

How fast does Androskat work?

When used correctly, the effect of Androskat usually occurs within 5 to 15 minutes. An erection then lasts an average of 30 to 90 minutes. The exact duration may vary from person to person. It is a lot less easy to apply than an erection pill. That is why it is essential to use the medicine with care and to know how to inject it. Advice and instructions from a healthcare professional are essential here.

What are the side effects of Androskat?

While Androskat may be effective, there are also risks. Common side effects include:

  • Pain or hardening at the injection site
  • Scarring or curvature of the penis during prolonged use
  • Prolonged erections (priapism), requiring medical intervention
  • Risk of infections due to incorrect injection technique

The full list of possible side effects can be found here in the package insert.

Acting incorrectly can have serious consequences. That is why intensive supervision by a doctor is necessary.

Why doesn't Fellos prescribe an Androskat?

At Fellos, we consciously choose care that is effective, safe and easy to apply at home. Androskat doesn't fit in there. It is a complex treatment that requires explanation, training, and medical monitoring. As a digital clinic, we want to lower the threshold for good care, but if we can't provide good care remotely, we won't do this. However, our healthcare professionals are here to answer any questions and give you advice.

In addition, our experience is that almost all men are well helped with PDE-5 inhibitors, such as sildenafil (the active substance in Viagra) and tadalafil (the active substance in Cialis). These products are more user-friendly, safe and scientifically proven effective. They work for the vast majority of men without the need for an injection. Out research it appears that more than 9 out of 10 men have been helped with these solutions.

Alternatives to Androskat

The most used and proven alternatives to Androskat are:

  • Sildenafil: usually works within 30 to 60 minutes and stays active for about 4 hours
  • Tadalafil: works after 30 to 45 minutes and lasts up to 36 hours

Both medicines are available from Fellos in different dosages. This way, we can adapt the treatment to your personal situation. During an intake, you can discuss with our doctors which dose suits you and specify your preference. You can also adjust the dosage later if necessary.

At Fellos, the entire process is completely online. Your medication will be delivered discreetly and free of charge, and our medical team is continuously available to answer any questions you may have.
