I'm on daily Letrozole, and Herceptin injections every 3 weeks until August this year. Amongst other delights, I've had fatigue and joint pain/swelling, especially my hands, which seemed to be getting worse. I know Herceptin is cumulative.
Then my husband got Covid and my Herceptin injection has had to be postponed for 2 weeks. It should have been a week ago today and for the past 4 days my hands have been so much less painful. It's been a blessed relief. But I am feeling quite unwell and utterly exhausted. I've tested negative all along so it isn't Covid - the symptoms aren't right in any case.
It made me wonder whether there is such a thing as withdrawal symptoms from Herceptin. I've Googled and nothing comes up, but the real experts are here so I thought I'd ask.
Hi, I've not come across this, but I have my final Herceptin injection next week. I've not had any side effects from the injections. My hands and joints can get a bit stiff from time to time, but I think that's the Letrozole. It's challenging to know what drug is causing what side effect sometimes. I hope your symptoms continue to improve,
