Using Medicines Safely
Keep a written list of everything you take, including supplements. Check active ingredients so you do not double up, for example paracetamol in cold remedies. Never share prescription medicines, and complete antibiotic courses as prescribed to help prevent antimicrobial resistance. Related: diseases database and medical disclaimer .
