How many medicines should I be taking for my symptoms of ADHD?
There are no easy answers to this and it is a very individual choice. Generally one medicine should always be the aim but combinations (often called “polypharmacy”) sometimes help. It is rarely of any use to combine drugs with similar ways of working. Below are some of the combinations that are used with the reasons. This is not a complete list but you might want to talk to your prescriber about any combinations not on this list you may be prescribed.
Usually either a stimulant (e.g. methylphenidate) or atomoxetine are used, unless you’re switching from one to the other. Sometimes low doses of some antipsychotics such as risperidone can help in combination with a stimulant.
| Main medicine | Second medicine | Reason |
|
Methylphenidate or dexamfetamine |
Atomoxetine |
While you’re switching from one to the other as atomoxetine takes a few weeks to start working. A very few people might do better with both together. |
|
Methylphenidate or dexamfetamine |
Antipsychotic (such as risperidone) |
ADHD not doing well just with methylphenidate or where some extra calming is needed. |
|
Methylphenidate or dexamfetamine |
Melatonin |
To help get sleep more regular. Usually only taken for a month or so. |
