Welcome to HCM!
Thanks for posting your query. I am happy to address your questions. There is a never-ending list of side effects with this drug. For fatigue and muscle weakness
which are sometimes unbearable would recommend you to do daily physical therapy
to optimize your energy and it will help with the muscle weakness, as well take calcium supplements
. For the dizziness
medication such as dramamine (dimenhydrinate) as required, can be taken and will resolve over few weeks. For headaches
you could take analgesics or painkillers. Hope I have answered your query. If you have any further questions, I will be happy to help.
