It's a generic antihystamine often sold as Piriton/Piriteze. Some viruses cause an allergic reaction similar to mild asthma and cause a dry cough. Over the counter at any pharmacy. I took half of a 10mg tablet for three consecutive nights after a fortnight of coughing. But note my comment about blood clots. It won't fix that.
