Lemsip max while breastfeeding?

I would suggest you do a google search, or pop to your local supermarket and speak to the pharmacist. They will be able to advise what you can take

Ask the pharmacist or take only paracetamol. There might be separate cough syrups you could take for the throat and you can use steam or vapor rub to help yourself with congestion but generally avoid antihistamines (usually in Lemsip) while breastfeeding. Always Google a drug before taking it while breastfeeding. For example: paracetamol is ok but cocodamol isn't. Etc

Anything with phenylephrine or other decongestants aren’t recommended in pregnancy or breastfeeding. However I have used a nasal decongestant while breastfeeding with no issues with supply on a couple of occasions as the blocked nose drives me insane and I weighed up the risks.

Highly recommend also taking lots of vitamin C while unwell. I take an effervescent tablet (1000mg Boots own brand) in a glass of water every morning and double or triple up when feeling unwell. Normally nips the cold in the bud.

It’s not recommended while breastfeeding and can tank your supply. Nasal sprays can be an option, a pharmacist may be able to advise

I was severely sleep deprived and didn't even think about taking some cold and flu tablets.. I only took two doses of two and my supply tanked completely, baby was screaming in hunger (lucky I had a freezer stash). The effect was short-lived and I think within 24hrs I was able to feed as normal but I was distraught and felt like the ultimate failure. I definitely recommend against it
