I suggest calling your pharmacist. They are usually much more accessible to talk to personally than drs and can be very knowledgeable about side effects.

Don't just assume it's old age. Calling to talk with the pharmacist or chemist, for more information, is a good idea,
and then possibly call your doctor office, to see if they might want to change it to a different option.
Meds cause lots of effects. There are sometimes better alternative meds, if we speak up.
