Antipsychotics

Use this tool to compare antipsychotics and their side effects

Antipsychotics can cause unpleasant side effects. Each drug differs in this respect. However, there are three effects that apply to all antipsychotics:
  1. Antipsychotic medications make you feel flat and take less initiative, as they dampen your emotions.
  2. The skin can become hypersensitive to sunlight, therefore stay out of excessive sunlight and use sunscreen.
  3. The higher the dose, the higher the risk of side effects.
You cannot predict in advance which drug will work best for you. It's a matter of trial and error. However, the side effects of the various drugs are more predictable - so you can make a choice informed by side effect profile.

What are antipsychotics?

During a psychosis, you experience the world around you differently. You may hear voices, see things or have paranoia. You also can be confused and feel anxious.

Antipsychotics block the effects of dopamine in the brain. This makes you a little indifferent, also with respect to your psychotic experiences. The antipsychotic also makes you feel calmer, less anxious and able to think clearly again. You also sleep better. The drugs help you to regain control of your life. They also prevent another psychosis from happening.
