Dalacin cream contains the active ingredient clindamycin phosphate, which is an antibiotic medicine. Clindamycin treats bacterial infections by killing the bacteria causing the infection. It does this by preventing the bacteria from forming normal cell walls. The cell walls of bacteria protect the bacterial cells and are essential for their survival. When these cell walls are not formed correctly it causes them to disintegrate and the bacteria therefore die. This inhibits the ability of the bacteria to grow and therefore stops the spread of the infection. Dalacin Vaginal Cream comes with 7 applicators
