Switched from lisinopril to losartan about a month ago. still have intermittent dry cough starts as throat tickle. is this lisinopril residual or does losartan cause a cough as well? unless allergies. several covid rapid tests negative so not sick?

If the dry cough and tickle throat have improved but not resolved completely, you should wait continue with Losartan. Sometimes, it takes months for those symptoms go away. If you do not feel any improvement, Losartan should be changed to a different category, not ACEi or ARB drug. Rarely but some patients still have those symptoms with Losartan, an ARB drug.
