Thank you for your question on ehealthforum.com
Your cholesterol levels as you can observe are high and need treatment. Lipistax is over the counter nutritional supplement available in America and doesn't need prescription. It contains some 6 natural plant sterols claimed by the manufacturer to lower LDL cholesterol.
FDA is the regulatory authority and it is mandatory for any prescription medicine to be approved by FDA before it can be prescribed for any condition. As Lipistax is not a medicine, it is not approved by FDA. In these cases it is left to the choice of user to his / her discretion to use it.
However, the claimed ingredients in Lipistax are plant sterols, can be effective in reducing cholesterol. But, it is difficult to endorse them without scientific studies. Thank you.
