Let's take a minute to talk about your medication. This is mirtazapine, and you should take it as directed. It can cause drowsiness or dizziness, so it is best to take your dose at bedtime. Because of this, you shouldn't do activities that require you to be alert, like driving, until you know how it affects you. Mirtazapine helps balance natural chemicals in the brain, so it can help depression and other conditions. It usually takes several weeks to start working. Side effects can occur, like dry mouth, constipation, mild dizziness or abnormal dreams. It's also normal to have an increase in your appetite and possible weight gain. If these or other side effects become reasons you want to stop taking it, please talk to your doctor or pharmacist. But, don't suddenly stop taking it unless your doctor says it's okay. To reduce side effects, avoid alcohol, and tell your doctor and pharmacist before taking any new medications, even if they don't require a prescription. Call your doctor right away if you notice any unusual changes to your body, including a rash, fever or feeling like you have the flu. It's very important to call right away if thoughts of suicide, or worsening mood or behavior ever occur, especially in children or young adults, because it could be a rare side effect of this type of medicine. For best results, read the medication guide, and consider asking a friend or family member to help determine how it is working for you.
