Why might I want to compare antipsychotics?
After considering how they can help and issues around taking them safely, you might want to know more about the different antipsychotics available to help you talk to your doctor about what's right for you. For example:
- If you have problems with a particular type of drug, such as first generation (older) antipsychotics, and want to avoid them.
- If you need your medication in a different form – for example, you may have problems with swallowing or find it hard to remember to take your medication correctly every day.
- If you have any dietary restrictions, such as being vegetarian or intolerant to some ingredients.
- If the drug's half-life is important to you – for example, if you are concerned about withdrawal effects and would prefer a drug with a longer half-life. For information about what the half-life means and why it matters, see our page about medication half-life.
- If you are worried about the impact of particular side effects, such as weight gain. For information about the side effects of a particular antipsychotic, you can look the drug up in our antipsychotics A–Z.
| Remember: drugs don't work the same way for everyone, and it's important to find a medication that works for you. See our page on receiving the right medication for more information. |
