Methyldopa, Oral Tablet

Methyldopa is one of the most popular drugs used for weight loss and other health benefits. Methyldopa is also known as methylcellulose or methenamine. It’s active ingredient is methylcellulose, which is a type of cellulose polymer found naturally in plants such as trees, grasses, roots and vines.

What is Methyldopa?

Methyldopa is a drug that helps with various symptoms associated with diabetes, including high blood sugar levels and insulin resistance. Methylcellulose can reduce inflammation in the body, improve circulation and promote healthy bone growth. It can also prevent heart disease. Methyldopasone (methotrexate) blocks the effects of T cells, which are immune system cells that attack cancerous cells and viruses.

How Does Methyldopa Work?

The drug works by increasing the amount of white blood cells in your body. White blood cells fight off infections and other harmful substances. When there are too many white blood cells, they produce antibodies against foreign invaders. These antibodies can cause problems if left unchecked, so it is good to have some number of them around. The more white blood cells there are, the better protection you will get from infection and other dangers.

Methyldopa works by increasing the amount of white blood cells in your body. This helps protect your body against disease and infection because you have an increased number of antibodies.
