colds and cold sore while pregnant- help please

[tab]

Pregnant - 15 weeks and all going fine. But Ive been struck down for 8 days with a chesty cough, blocked/runny nose, sore throat, headache, no smell/taste, which just doesnt want to budge. I have found myself taking some paracetamols in desperation as ds1 (2) has also come down with similar and has been out of sorts. (he's ok with calpol and amoxicylin). However, now Ive got a cold sore too. Of course pharmacist wont give me anything and says go to doctor. Perhaps I should but Im loathe to go to doc for a cold sore. I dont think he's going to be able to prescribe anything if the pharmacist couldnt think of anything. Ive tried looking on the internet and some site mentioned cream with lemon balm in it but I dont have any names. Licqorice tea is meant to be good - but then I noticed it has a pregnancy warning on it (y0u know what I mean!).

Help!!!! Im feeling very sorry for myself !
Has anybody had coldsore while pregnant, please tell me if you found some remedy.

I've been using boots cold sore location for years, it drys the cold sore up and is normally gone in a week, it's safe to use in pregnancy too.

I am 23 weeks, have a cold sore and am using Zovirax. I have used it in all.3 of my pregnancies when needed.

Just realised this is a zombie thread. Doh.

Cold sores and compeed patches nothing helps mine other than these... I’ve got two nasty ones pop up.. pharmacist won’t advise, midwife hasn’t got back to me and I can’t get in to see the doc... anyone got any advice ....

@George91
I’ve used compeed patches during this pregnancy - 30 weeks now. My rational - they contained the outbreak and prevented me ending up on higher strength medication. Like Other cold sore meds, they won’t officially be labeled safe as they haven’t been extensively tested BUT my gp explained are routinely used. Hope this helps reassure

Thank you love! I’ve had to pop one on through fear of it spreading or developing further!! Also full of cold so didn’t want it all over my nose. The joys of a low immune system!! 30 weeks eeek - almost there now!!
