I am an American on a European vacation. I got very sick. Headache with thick yellow mucus and sore…read morethroat and cough. The doctor tested for strep but it wasn't. He gave me ear drops, nasal decongestant, paracetamol, and Pretuval C. The next day I began feeling better and the mucus was less and less. Only thing is drugs are in German so I couldn't read it. For any English speakers if you receive Pretuval C don't chew it! It's an effervescent tablet that needs to be dissolved in water! Oh and it cost me $180. Doctors come quick. I will show the receipt to my American insurer and try to get reimbursed. This place was a godsend as I was in Europe on Christmas Day.
