Boric acid wash for vagina can be used in resistant cases, as an alternative measure with the consultation of your physician. A specific culture; Nickerson or Sabouraud mediums should be performed in refractory or recurrent cases of vaginal candidiasis to confirm the infection. So you can talk to your doctor to get this culture before you start the treatment.
Women who do not improve with above can use, clotrimazole 500 mg vaginal suppositories administered once per week for six months which is also effective.
Also avoid (if you do) following;
1) panty liners,
3) sexual lubricants
Over the counter vaginal probiotics and oral probiotics would help in restoring the normal vaginal pH and bacterial flora which will eliminate the odor.
The other possibility of diagnosis to consider would be mild bacterial vaginosis. Following are the treatment modalities;
1) Metronidazole (flagyl) and clindamycin have been the drugs of choice.
2) Azithromycin too is effective, especially if there is recurrence or persistence. Secnidazole, ornidazole and tinidazole are also used in the case of antibiotic resistance.
3) Antiseptics as vaginal suppositories;
c) dequalinium chloride,
d) polyhexamethylene biguanide,
e) povidone iodine
f) hydrogen peroxide
5) Stop douching or bubble bath, if you do.
6) Avoid liquid soaps and body wash.
