A new law that limits the sale of drugs containing pseudoephedrine has been passed in the Czech Republic, so most of the multi-symptom cold medicine that contain the substance (brand names are Modafen or Paraben Plus) are now available only after presenting I.D. For a similar drug that contains acetaminophen, pseudoephedrine, caffeine and vitamin C to help you through the worst, ask for Coldrex, available without ID and in tablet and powder form (the powder has 700mg of acetaminophen, as opposed to 500mg in the tablets)
