Suprecur nasal spray - cold sore breakout

Hi everyone,

I started taking suprecur (burselin) nasal spray on Saturday and I've broken out in cold sores on my lip. Has anyone heard of this being a side effect? I have had cold sores in the past on the odd occasion but have taken 2 in the space of 2 days, not sure if it's related but any advise greatly appreciated. Thanks!

Hi Marie_83. Sorry to hear that you are suffering from cold sores. There is nothing to say that Buserelin can cause them, so perhaps you have been a little run down for them to erupt. Unfortunately, once you have had one, you are susceptible to having them again if you become a bit tired or run down. If they persist you will need to see your GP for his/her advice, as it is something you don’t need if you become pregnant. Good luck with the cycle. Diane


Thanks Diane, much appreciated. Can they cause serious problems if you are pregnant?


Hi. “Cold sores” are only a problem if you catch the herpes virus for the first time during your pregnancy, when there would be a very high likelyhood of passing it on to your baby. So no worries as you already have had it. Diane
