On Wednesday, my husband was told by dr that he had pneumonia. He was prescribed augmentin plus clavulanic acid & ibruprofen. When at the Chemist getting prescription, I asked for a suitable cough syrup. I wasrecommended Prospan a Bronchial Syrup, Dried Ivy leaf extract. Last night he was very itchy & had developed red itchy hot blotches on his body espescially on his knees. We think it s the Prospan syrup that he s allergic to. I have some hayfever (anti-histamine) tablets. Would it be ok to take one while he s on augmentin? He has stopped taking the cough syrup. Thank you
