What was the dosage your doctor advised. I give it once daily, every day, for as long as needed. Interferon has to be ordered - to get it quickly, try a hospital pharmacy. It must then be diluted for oral use. In case you don't have the instructions for this, I am adding below the handout from Dr. Gary Norsworthy on interferon.
Lysine is available in health food stores.
The following is a section from my seminar handout on interferon. It accesses the immune system through the oral pharynx, especially via the tonsils. Because it is a protein, it is degraded quickly in the stomach. Therefore, it must be squirted into the mouth and not syringed through a feeding tube directly into the stomach. The medication is tastless.
