The effect of Myzlin tablets in the treatment of different diseases varies from one event to another. For the early stages of varicose veins, i.e. stages 0-1, the effect usually appears in 1-2 weeks, while for the middle stages 2-3 and the late stages 4-6, the effect usually appears in 2-4 weeks. For the prevention of post-phlebitis syndrome, the effect will also appear within 2-4 weeks, for many cases of post-operative edema the effect will appear within 3-5 days, and for lymphedema the effect will usually appear within 2-4 weeks, so the judgment of how long to take Myzlin for effect depends on the underlying disease.
