heres info:
Ask the pharmacist. Call several different ones and see what they say.
What other medications do you take? Are you on any statins (cholesterol medications)? Those medications can cause muscular pain.
Another thought could be the possibility of vascular disease? Does it hurt when you walk?
You may want to see your doctor about your symptoms, they can do a test called ABI’s, this will determine if there is adaquate blood flow through your legs. Arterial disease in your legs can cause them to feel very heavy and tired. It can also cause pain in your legs when you walk. Mention it to your doctor and see if this might be a possibility?
Hope this was somewhat helpful.
