Strepsils Anaesthetic formula Blackcurrant with Antiseptic and gentle anaesthetic action work really well for sore throats. I used to get throat infections all the time as a child, and my doctor would always recommend Strepsils. I have not taken them in years, but on my last stock-up trip to the pharmacy, I picked up a box of 24 just to have on hand if needed. I am so glad that I did that, as I just recently had a cold that started with a sore throat. I used my Strepsils, and they really helped to ease the pain. From now on, these will be my go-to remedy for a sore throat, and they taste pretty good, too!
