There are many different anti-fungal creams that can be used for the treatment of athlete’s foot. All of these are safe to use in pregnancy. Your local pharmacist will be able to give you advice regarding which to use initially. If the infection doesn’t respond to treatment, you will probably be advised to see your GP. There is a slightly different and stronger anti-fungal which your GP could prescribe if necessary. You wouldn’t want to take anti-fungal tablets during pregnancy but these are rarely needed in the treatment of athlete’s foot.
Keeping the affected area dry and open to the air as much as possible will also help get rid of this problem.
