To help reduce swelling in the cheek after sinus surgery, scientific research has studied taking three 10-milligram doses of serrapeptase one day prior to surgery, one dose after surgery, and three doses a day over the next five days, according to WebMD. For other uses, more research is needed.
Serrapeptase aids in the breaking down of protein, which may help reduce mucous and inflammation and is possibly effective for the treatment of facial swelling after sinus surgery, states WebMD. There is insufficient evidence to support the use of serrapeptase to treat other conditions, although early research suggests it may be effective in the treatment of chronic bronchitis, sinus pain, laryngitis and sore throat. Short-term use of serrapeptase by adults appears to be safe, but the long-term effects are unknown.
