If you're one of the many who fear needles, you might be in luck. Researchers at MIT and Massachusetts General Hospital are working on an oral alternative to injections, and it involves the use of a capsule. On the pill's surface, tiny needles inject drugs directly into the lining of the stomach once it's swallowed. During trials, insulin was delivered more efficiently, and the capsule didn't cause any issues as it passed through the digestive system. While insulin was used in tests, the delivery system is said to be most helpful for antibodies to treat cancer and autoimmune disorders. At any rate, those of us who prefer to avoid shots entirely may soon have one less source of anxiety during doctor's visits.
