From the Guidelines
Miconazole is a recommended treatment for vaginal yeast infections caused by Candida, with various formulations available, including a 2% cream, 100mg suppository, 200mg suppository, and a 1200mg suppository. For uncomplicated vaginal candidiasis, the Centers for Disease Control and Prevention (CDC) recommends using miconazole vaginal cream (2%) once daily for 7 days or miconazole vaginal suppositories (100mg) once daily for 7 days, preferably at bedtime 1. Alternatively, higher-dose formulations are available, such as 200mg suppositories for 3 days or a single 1200mg suppository for one-time use.
- Apply the medication deeply into the vagina using the provided applicator.
- Continue treatment for the full course even if symptoms improve quickly.
- Avoid sexual intercourse during treatment or use condoms to prevent reinfection. Miconazole works by disrupting the fungal cell membrane, preventing Candida from growing and reproducing.
- Side effects are typically mild and may include vaginal irritation, burning, or itching. If symptoms persist after treatment or recur frequently, consult a healthcare provider as you may need a different antifungal medication or further evaluation 1.
- Avoid using tampons during treatment as they may absorb the medication. It is essential to note that the diagnosis of vulvovaginal candidiasis should be confirmed by a wet-mount preparation with use of saline and 10% potassium hydroxide to demonstrate the presence of yeast or hyphae and a normal pH (4.0–4.5) before proceeding with empiric antifungal therapy 1.

From the Research
Miconazole Treatment for Candida Vagina Yeast Infection
- Miconazole is an imidazole agent that is preferred for the treatment of vulvovaginal candidiasis due to its greater efficacy, shorter treatment regimens, and ease of administration 3.
- Different formulations of miconazole are available, providing clinicians and patients with the opportunity to select the most appropriate agent 3.
- A study compared the safety and efficacy of bedtime versus daytime administration of the miconazole nitrate 1200 mg vaginal ovule insert to treat vulvovaginal candidiasis, and found that both daytime and bedtime administration were effective and had similar side effects 4.
- Miconazole is often used as a local treatment for acute vaginal yeast infection, with a success rate of 84-90% 5.
- The treatment of chronic, recurrent, and resistant forms of vaginal candidosis may involve prolonged local and/or systemic therapy with miconazole or other antifungal agents 5.
Comparison with Other Treatments
- A study compared the efficacy of single-dose oral fluconazole with 3-day intravaginal clotrimazole in the treatment of vaginal candidiasis, and found that fluconazole was more effective in the long term and relieved symptoms more rapidly 6.
- Another study proposed a combined therapeutic approach using systemic fluconazole and topical metronidazole and clotrimazole for the treatment and prophylaxis of recurrent candidiasis 7.
- Miconazole is one of several antifungal agents available for the treatment of vaginal candidiasis, and the choice of treatment may depend on the severity and recurrence of the infection, as well as patient preferences and medical history 3, 5, 4.
