Cystitis relief sachets might decrease the effectiveness of Nitrofurantoin, so we do not recommend combining the two.
Cystitis relief sachets should be taken as a first line treatment for a UTI, if you have finished the course of sachets and your UTI symptoms are still present you may require treatment with antibiotics.
While all the ingredients in the sachets are natural with a palatable cranberry flavour, mixed with water, they work to minimise bladder irritation and rehydrate you, which in turn will reduce UTI symptoms. You may still need antibiotics as they work by killing the bacteria which is causing the infection.
