Hi, Evion LC contains both levocarnitine and vitamin E that is used in the treatment of muscle cramps as well as strengthening and improving the muscles for making them stronger. It helps in relieving pain and inflammation of the muscles as well as enhancing proper growth and functioning of the body. But, like other medications, this medication has some minor side effects too. Side effects of Evion LC are nausea, vomiting, diarrhea or constipation, headache, GIT upset, abdominal pain or cramps, nail discoloration, tingling sensation, garlic odor of breath, unusual tiredness and weakness, fall on blood sugar level, dizziness, allergic reactions etc. These side effects are mild and go away over time as the body adjusts to this medication. But, any of these side effects persist for long or bother you, then you should consult your doctor first for medical help. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Zubayer Alam, General And Family Physician
