Softening of earwax
SB-Must 500 Tablet is a liquid solution that helps to soften, disperse and sometimes dissolve ear wax. Although ear wax drops can be an effective, self-sufficient treatment for ear wax, they are more often used before some other form of treatment for ear wax such as ear syringing or ear irrigation. This medicine is absorbed by ear wax, aiding in thinning and softening it in the process. It softens the hard and dried ear wax and enables its easy removal. This helps in getting rid of the earwax without pain and discomfort.
