I just started taking 50mg of Zoloft/Sertraline a couple days ago. The plan is to switch over from Effexor because the side effects have been killing me. But I was wondering, are chapped lips a symptom of Zoloft? Ever since the morning after I took my first dose I’ve had swollen, cracked, bright red lips and they burn and itch under the skin. I’ve been applying lip balm and oil like crazy but it’s not getting better.
