Hi I recently have been taking a hayfever treatment, I am also on cerazette and betablockers (for heart trouble).Me and my Partner share a good sex life and have sex often. I hace been on Cerazette for just over a yr now no issues there, but since i started the hayfever tablets i getting food cravings, feeling sick and forever felling tired. I read through the leflet for hayfever treatment and found out it contains anitibiotics which would techniqly over ride my cerazette. worried about beeing pregnant any help would be great help thanks.
