I am not sure what your allergies are as Felopio is being marketed as a herbal product, and herbal medicines can have a lot of potential allergens.
Although saying that, it does not necessarily mean you will react. The company has not been listed in any medical source so cannot tell you what the ingredients are.
On the other hand, your infertility
specialist will be in a better position to tell if she has experience with this product. There are various herbal tampons available, another example being fallopen that apparently provides a kit with a dvd, ingredients list etc.
Discuss this with your specialist before trying any of these products.
If you know what your allergies are, and have the list of ingredients available but still unsure, please write back to me.
