I get really evil hayfever (have had to get a steroid shot before because I was already on the highest meds possible and there was nothing else) and my lung capacity is really poor, so there's no way I can cope without meds. Alternative meds take the edge off but mid-season I still struggle.
My dr said that anything local was no issue (inhaler, nose spray, eye drops) but that tablets could cross over to the baby. My prescription was changed to a different type of tablet - I was on fexafenadine (found in Telfast), I'm now on loratadin (found in Claritin).
