Girls, hello everyone! I have such a question... I was on bed rest for 13 weeks, gargling with soda and salt, drank plenty of water + making beetroot with honey. Now a cough started, phlegm very thick and doesn't come up. The doctor prescribed Ambroxol, but I bought Ambrobene? It seems like the composition is the same, but I'm kinda nervous ? What did you take?
