I have been on citralopram for a year and have recently had a red rash appear round my waist and hips. it's not itchy, could it be a side effect?

Unlikely: Most side effects occur within the first çohple of weeks of tf a king a medication. What you decibels sounds more like a contact dermatitis to a new laundry detergent or new pants or under garments. A drug rash would usually be all over the body. I would suggest you have it checked out if it persists, but I dooub f any connection to citalopram
