Remeron Side Effects
Although most people have no problems when taking Remeron, side effects are possible, such as drowsiness, dry mouth, and an increased appetite. In many cases, these side effects are minor and easily treated. However, some side effects should be reported to your healthcare provider, including suicidal thoughts, hallucinations, and signs of an allergic reaction.
An Introduction to Remeron Side Effects
As with any medicine, side effects are possible with Remeron® (mirtazapine). However, not everyone who takes it will experience problems. In fact, most people tolerate the medication quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can be easily treated by you or your healthcare provider.(This article covers many, but not all, of the possible side effects with Remeron. Your healthcare provider can discuss a more complete list of Remeron side effects with you.)
