• blood tests to check your white blood cells due to a potential side effect, a significant decrease in the number of certain white blood cells in the blood (agranulocytosis)
• an ECG (electrocardiogram) to check your heart is working normally, as certain medicines in the same family as Levomepromazine (antipsychotics) can, in very rare cases, cause heart rhythm disorders (see section 4).
