I doubt whether you have any heart disease
. Usually Ubidecarenone and L carnitine are advised as a part of anti oxidant medicines in those diseases. Side effects are few such as occasional bowel upsets,nausea and rashes if you are allergic. Statins, Vit B complex, calcium has few side effects. But taking oral steroids for a long duration will lead to a lot of side effects as they will lead to more osteoporosis
,more risk of fractures, diabetes, hypertension, more infections, puffiness of face, obesity.You also should be cautious while taking occasional theophyllines. It may lead to nausea, vomitting, and in high doses it may lead to seizures, arrythmia
. Except oral steroids,all the medications do not cause any serious side effects.Don't get dissapointed. Hope, I satisfied your queries.
