Just wondering how many of you took Tadalafil while on hormone treatment and radiotherapy, I understand the need to keep a good blood flow to the old gentleman downstairs but I’m reluctant to take more medication if it’s not needed 

When I asked the specialist nurse she seemed to imply it was personal choice and not essential

so how many of you did or didn’t and if you did how long did you take them for and did you experience any side effects 

  • I would say yes get it if you can! I wasn’t given that option and after over a year of inactivity it a slow road back but still trying!

  • I have them on repeat prescription 

  • Hello  

    I was aware of it, but because of already being on lots of other medication decided to give it a miss.

    After 3 years HT and RT I didn’t need A testosterone test to tell all was back to normal Innocent.

    I think I was back up and running within 2/3 months.

    Best wishes - Brian.

  • I started taking it 6 months into HT, and I'm still on it. No additional side effects. I have it as a repeat prescription.

    Like many other HT things, these side effects build up over time, if you are due to have HT for more than a year, I think it's worth having.

    Hope this helps

  • Hi,

    I am on HT since Jan (Orgovyx 3 years and Abiaterone 2 years) and finish my 20 sessions of RT tomorrow. That is a long time to be 'out of action'.

    My research suggested that there could be a case of 'use it or lose it' ie to keep the tissues healthy and flexible and avoids fibrosis. I had used cialis (tadalafil 10mg) for a few years with great results (private prescription), so I asked my onco to prescribe a daily 5mg, which he willingly did in February  and is now on free NHS repeat prescription via my GP. He also said 'don't expect miracles' whilst on RT plus a few weeks!

    Nevertheless, I added to my cocktail (!) of pills with no bad side effects and immediately saw a reversal in my penis shrinkage, so at least it's a lot easier to 'point Percy at the porcelain' (which I do a lot, thanks to the RT). Libido is low but 'with encouragement' I can get a soft erection on demand. I think that's good to keep the blood pumping there if nothing else, albeit not much good for penetrative sex. Today my penis pump has arrived and I am going to give that a try... 2-3 times per week is recommended (even without sex, (I should be so lucky)) to keep penile health.

    Unexpected(?) bonus.... The most common (and dangerous) side effect with Abiraterone is raised blood pressure. Mine has dropped from marginal to acceptable (135/75) levels since adding Tadalafil. I shouldn't have been too surprised as the drug was originally developed for BP lowering purposes - the welcome side effect discovered during the trials has been a game changer for many and made someone a lot of money.

    I will probably choose to be on 5mg daily it till my testosterone comes back and then back to 10mg occasional use when needed, hopefully without the pump! Only 2.8 years to go...

    Yes, it is a personal choice. This is just my view, hope it helps you decide.

    Stay strong!

  •  Hi     I was on Prostap for 13 months (to last injection October 2024) and had 20 fractions of RT in that period. I only learned about Tadalafil from this forum and asked my specialist nurse about it in April 2025, she agreed and from May 2025 I have been taking it daily with repeat prescriptions from my GP.

    Now after eleven months I can report that it has helped with counteracting the atrophy and to some degree with the PD but things are by no means back to how they were before treatment started. I am asking for a Testosterone test every six months at the same time as my PSA test and currently can report that has not risen far from the negligible level that it was whilst I was on the Prostap, time will tell I hope.

    All in all I would recommend that if your GP will prescribe Tadalafil you take up the option.
