Hi Anthony
Injecting subcutaneously has apparently reduced the side effects of Velcade compared with IV injections. The only immediate effects I got were regular injection site reactions and mild constipation – by mild I mean it only lasted a couple of days or so. I was injected on Thursdays and I was regularly constipated from part way through Saturday to part way through Monday. I didn’t take anything for it because I didn’t want it to swing violently to diarrhoea after a couple of days.
Velcade gave me peripheral neuropathy (PN) in my toes starting I think during the 3rd cycle and it gradually got worse during the 4th cycle, which was the last before my SCT. My cycles were 5 weekly – 4 weeks of treatment and 1 week gap. My PN is not debilitating in any way. I don’t notice it when I’m walking. It’s particularly noticeable when I sit watching TV in the evenings, especially if I kick off my slippers and wiggle my toes. It also affects the area of my foot just behind my toes that stays in contact with the ground when I lift my heel.
I have read that CTD PN can be permanent and Velcade PN tends to be reversible, but my experience so far is the opposite. My first treatment was CTDa and I was switched to Vel/Dex after 4 cycles because my paraprotein level seemed to have plateaued. I got PN in my hands from the 4 cycles of CTDa and it has cleared up completely. I’ve still got the PN in my feet caused by the Velcade, and so far it has shown little if any sign of subsiding. I have also got some numbness and tenderness in certain areas around my knees, which is not exactly what you think of as peripheral, but when I asked my consultant whether it might have been caused by the Velcade he said yes without hesitation. My thighs also feel like I’ve been doing lots of squats, but I first noticed this after my SCT so it might be associated with the high dose Melphalan.
Just my experience.
