Vaginal suppositories are solid, often oval-shaped medications that are meant to be inserted into the vagina. The medication warms to the temperature of the body and becomes liquid in order to be easily absorbed. Vaginal suppositories have a wide range of uses including treatment for: fungal infection (like yeast infections), vaginal dryness, bacterial vaginosis, hormonal or non-hormonal birth control, and to administer hormones like estrogen.
