Polycystic Kidney Disease (PKD) Support Group

Polycystic kidney disease (PKD) is a progressive, genetic disorder of the kidneys. It occurs in humans and other organisms. PKD is characterised by the presence of multiple cysts (polycystic) in both kidneys. The disease can also damage the liver, pancreas and rarely the heart and brain.

Marijuana oil

Hi All! New to the group, I was diagnosed with AKPKD about a year back, my kidney function is pretty normal currently. Hoping to keep it that way for as long as possible! I met with a new doctor today who wants me to start BP medication even though my bp is in the normal range. He also adviced me to start Tolvaptan, I'm a little reluctant since it's still in trial. Just wondering if anyone is doing it and also if anyone has tried marijuana oil to slow down the process. Thanks for sharing! 



Hi najia, welcome to the group. Tolvaptan has been licensed in England for those with PKD stage 2-3 with rapidly declining function. These are not the best criteria in my opinion, but who am I to say?! As you say, the aim is to maintain good function, so why wait until it's rapidly declining. These criteria reflect the testing and demonstrated effectiveness, however. The drug has not been tested in those at stage 4+, and that's probably rather too late anyway. It is also untested in those aged 50 and over. There are side effects, but if you tolerate them and it gives you several years more with good kidney function, I think it's worth a go. I decided against it because I am at stage 4 now and would probably gain only a few months grace before needing renal replacement therapy. I'm also nearly 50 and already have a difficult time with frequent urination, which Tolvaptan is known to cause. You have to drink a lot, which I'm not sure I could manage. Thus is crucial, as you become very dehydrated if you don't drink enough. For me, it's about quality of life now as much as anything else.

With blood pressure, many doctors, but not all, tend to want to keep our blood pressure a little lower than the generally accepted norm. What is your BP?

As for marijuana oil, I'm afraid I know nothing about it.

Interesting! I'm in Canada. I had this discussion with my nephrologist yesterday. I'm still stage one and my kidneys are very large. Why eGFR is about 112. As far as Tolvaptan goes she doesn't think the side effects would outweigh the benefits for me. She also mentioned the blood pressure medication study. My blood pressure is great so she did not recommend starting me on blood pressure medication... it's confusing isn't it? I haven't heard anything about marijuana oil.

I have not heard of marijuana being used to slow the progression of PKD, but it is definitely recommended to treat PKD related pain

    Hi I'm 42 years old and have pkd. I got diagnosed 3 years ago and recently my GFR fluctuates between 13-20%. Does anyone else have this problem?? It dropped and they had me get a fistula placed for dialysis. Now it's back to 19% and my Dr is questioning my symptoms. I am exhausted and have vomiting/nausea. Some days seems a little better than others. I really have no energy for nothing.  Now I'm...

    teen with PKD

    hi, I am 16 and was diagnosed with PKD 3 years ago. I've always had mixed feelings about my diagnosis. On the one hand, i have seen what several of my family members have had to go through with dialysis and transplants. However it doesn't feel real because I have no symptoms. I had an ultrasound recently, and seeing the cysts on screen was hard to experience. I joined this group because I wanted...
