How will my antipsychotic interact with other medication?

Interaction problems are uncommon, although a few have been recorded.

Some antipsychotics can interact with tricyclic antidepressants or anticholinergic medications (e.g. procyclidine, which may be given to help with movement side effects). This interaction may produce a dry mouth, blurred vision, constipation and difficulty in passing urine.

Due to the sedative effect of some antipsychotics, care should be taken with sleeping tablets, tricyclic antidepressants and benzodiazepines among other medications. There are a number of possible interactions with medication, so it is important that your doctor knows about all the medicines you are taking.

Can I drink or drive on my medication?

Many antipsychotics can impair alertness, concentration and driving performance.

Antipsychotics can cause sedation, impair coordination and response-time. Effects are particularly marked at the start of treatment and after increasing the dose. It is important to stop driving during this time if adversely affected. The use of alcohol will further increase any impairment.
