Fotalin is divided into two types, one is oral Fotalin and the other is topical Fotalin. The most important effect, whether oral or topical, is to relieve pain, especially in rheumatoid arthritis, osteoarthritis and other kinds of joint inflammation, which have a significant effect on fighting inflammation. It also has a good control effect on the pain and swelling that occurs after injury. For pain caused by feeling wind-cold and rheumatism, it also has a good effect on improving the symptoms. Oral fotarine can also be used to relieve pain after surgery, trauma, labor injury or nerve injury, and to promote sleep. Topical fotarine has a good pain relief effect for soft tissue injuries, provided that the skin is not broken, but fotarine should not be used in large quantities for a long time.
