Pregnant women can safely use Monistat while they are pregnant to treat yeast infections, notes Mayo Clinic. They can use it at any point in their pregnancies, and typically see the best results when using seven-day formulas.
Pregnant women are highly susceptible to yeast infections due to pH balance fluctuations, states Mayo Clinic. Products such as Monistat that contain miconazole are safe, but women should avoid antifungal medications and home remedies when they are pregnant. Vaginal itching and white, thick discharge are symptoms of yeast infections, and pregnant women should verify with their doctors that they have the condition before treating the symptoms with Monistat or other drugs.
