Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Cansoft-CL contains Clindamycin and Clotrimazole as ingredients, both of these drugs belongs to category B in pregnancy means animal studies have proven no harmful effect to the baby. So, these drugs are considered as safe during pregnancy. At present you can use the drugs as prescribed by your doctor. But taking the drug once a week till the end of the pregnancy may or may not be needed depending on your symptoms. If you persistent to have white discharge with symptoms like itching, burning you can go for the treatment as suggested by your doctor. If not physiological white discharge with out any symptoms can be treated by taking local vaginal wash like Clingen wash or Vygene wash, etc., which will help in reducing the discharge and you can feel comfortable. Hope I have answered your query. Let me know if I can assist you further.
