Hello Mohamed Thank you for posting your query in healthcaremagic. No,Losartan does not dry cough. You might be having dry cough due to some other reasons like smoking,dust,any kind of allergens,infection,cold etc.My provisional diagnosis would be bronchitis,asthma.These symptoms might also accompany with difficulty breathing, chest pain, rapid heartbeat, or swollen legs or ankles if it is a heart disease.I would have liked you to go for an Xray chest (if your cough is for long time),pulmonary function test,ecg(to rule out any heart disease). I would advise you to reach a doctor and go for thorough examinations to come to a confirm diagnosis.Till then avoid any kind of allergen and try to take rest. Hope i could help you.Take care
