Mirtazapine for depression

About mirtazapine

Mirtazapine is a type of antidepressant used to treat depression. It works by increasing the amount of noradrenaline and serotonin available in your brain. This can help ease the symptoms of depressão.

Brain cells, called neurons, release a number of chemicals which go on to stimulate other neurons. This leads to electrical impulses which result in the many functions controlled by your brain, including mood. Noradrenaline (norepinephrine) and serotonin are two chemicals released by neurons.

The most common side effects of mirtazapine are:

• Feeling sleepy, dizzy, or tired.

• Dor de cabeça.

• Dry mouth.

• Increased appetite and weight gain.

You may also experience other side effects such as:

• Enjoo (náusea).

• Diarreia.

• Disturbed sleep.

• Feeling anxious.

• Rash.

• Swollen feet and ankles.

• Dores e desconfortos.

• Feeling shaky.

You will find a full list in the manufacturer's information leaflet supplied with your medicine. If any of these symptoms become troublesome, speak with your doctor. If you experience any other symptoms which you think may be due to this medicine, discuss them with your doctor or pharmacist.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking mirtazapine it is important that your doctor knows:

• Se você está grávida, tentando ter um bebê ou amamentando.

• If you have any heart, liver or kidney problems.

• If you have low blood pressure (hypotension).

• If you have ever experienced any problems passing urine.

• If you have ever had a seizure, or fit.

• Take mirtazapine exactly as your doctor has told you to. It is generally prescribed as a once-daily dose, at bedtime.

  • There are several strengths and types of tablet available, so your doctor will tell you which is right for you. This information will also be on the label of the pack you have been supplied with.

• If you have been given an orodispersible tablet, these are made to dissolve in your mouth so that you can swallow them without needing a drink of water. Remove the tablet carefully from the wrapper (by peeling back the foil) and place it on your tongue. Make sure your hands are dry before touching the tablet.

• Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress.
