If you are pregnant and find that you have ringworm, you have several treatment options. Before beginning any treatment, though, you should consult with your doctor to confirm that you have ringworm and to discuss treatment options.
Ringworm is a fungal infection that can affect the skin, scalp or nails. It can be spread from human to human or from animals, such as cats and dogs, to humans. If you contract ringworm during pregnancy, it is not harmful to your unborn baby.
Ringworm appears as a flat, scaly circle on the skin. As the patch grows, the centre begins to clear up and all that remains is a ring, as the name implies. You may have only one patch, or several may develop in an area of the skin. The patches may be itchy.
Your doctor may prescribe a topical cream containing nystatin and triamcinolone to treat the infection. Apply a thin layer to the affected area twice daily until the rash has cleared. This medication is FDA category C, which means it is not known to cause risks during pregnancy, but they have not been ruled out either.
An over-the-counter cream or ointment containing clotrimazole, such as Lotrimin, may be used to treat ringworm. Apply twice daily to the rash. It is a good idea to continue use for a week or two after the infection clears to prevent reoccurrence. Clotrimazole is FDA category B, meaning there is no evidence of risks to humans during pregnancy.
Although tea tree oil is sometimes used to treat ringworm, it should not be used during pregnancy.
If you are hesitant to use medications while you are pregnant, ringworm will eventually clear up on its own. It may take several months, though, so this may not be the best option for you.
