The effect of levocarnitine oral solution is mainly based on the individual’s constitution and the severity of the disease, and usually has a therapeutic effect in about 3 weeks. It is used to prevent and treat low blood levels of carnitine, a substance synthesized from fatty and dairy products. This drug helps to help break down the long-chain fatty acids that the body takes in from food, by effectively breaking them down for energy and keeping the body healthy. If the level of this substance in the blood is too low, it cannot effectively break down the long-chain fatty acid substances in food and can lead to a lack of energy in the body. Low carnitine levels can occur clinically in people on dialysis due to severe kidney disease and in people using medications such as valproic acid and zidovudine. In addition low carnitine levels can lead to liver, heart and muscle problems, so if such problems are detected this drug can be injected to replenish the carnitine levels in the body.
