Prostap injection.

Hi Jewelse2b714 sorry to hear that your dad has been diagnosed with PCa. Thanks for the info about diagnosis, are you able to tell us if any other treatment has been prescribed or is the Prostrap the first medication?  I have been on Zoladex for 8 years (which is similar but slightly different) so can’t speak with knowledge, but I would doubt that the HT would have such an instant noticeable impact in 36-48 hours.  Is his jab monthly, quarterly or 6 monthly?  Personally, any noticeable changes following treatment I usually contact my team for advice/reassurance.  

I don't think it works that quickly ! The side effects are not from the drug they are from having lower testosterone levels. As testosterone does not decline immediately (takes weeks or months) the side effects work on a similar timescale.

There may be a physiological effect of relief from having the first injection over with which may make the patient feel tired. I found this with some of my treatments particularly the biopsy which made me feel very tired and emotional afterwards.
