Spotting and periods coming a few days early are common reasons doctors prescribe a short course of medicine to regulate the cycle. Whether it's safe alongside your epilepsy treatment isn't something to decide without your neurologist's input.
Next Steps
Please check with your neurologist before starting it, and let your gynaecologist know every medicine you're already on.
Health Tips
Don't skip telling either doctor about the other's treatment, since epilepsy medicines can interact with hormonal ones.
