Oral formulations of piracetam.
Myoclonus of cortical origin
Treatment of adult patients with myoclonus of cortical origin, in conjunction with other anti-myoclonic therapies, regardless of aetiology.
Initial dose: 7.2g daily in 2 to 3 partial doses.
Dose can be increased by 4.8g per day every 3 to 4 days, depending on patient response.
Maximum dose is 24g daily.
Patients with Renal Impairment
Creatinine clearance 50-80ml/min: Use two thirds of the usual daily dose, in 2 to 3 sub-doses.
Creatinine clearance 30-50ml/min: Use one third of the usual daily dose, in 2 to 3 sub-doses.
Creatinine clearance 20-30ml/min: Use one sixth of the usual daily dose administered once daily.
Creatinine clearance less than 20ml/min: Contraindicated.
Additional Dosage Information
Continue treatment with piracetam for as long as the original cerebral disease persists. In patients with an acute episode, spontaneous evolution can occur in time, so every 6 months an attempt to decrease or discontinue treatment should be made. This should be done by reducing the dose of piracetam by 1.2g every 2 days.
(In the case of a Lance and Adams syndrome this should be reduced to every 3 or 4 days to prevent the possibility of sudden relapse or withdrawal symptoms.)
Other anti-myoclonic drugs should remain unchanged at their optimal dosage.
An attempt can be made to subsequently reduce the dosage of the other anti-myoclonic drugs, based on the individual clinical benefit.

Pregnancy and Lactation
Piracetam is contraindicated in pregnancy.
The manufacturer recommends that piracetam must be avoided during pregnancy unless the benefit for the mother exceeds the risks.
According to the manufacturer, piracetam crosses the placenta, with newborn levels being 70% to 90% of maternal levels.
Animal studies have shown no increased risk of teratogenic effects. There is no adequate information on the use of piracetam in pregnant women to date.
Piracetam is contraindicated during breastfeeding.
The manufacturer does not recommend breastfeeding while taking piracetam. A decision to discontinue piracetam therapy or breastfeeding should be made, taking into account the benefits to the child and impact on the parent.
Piracetam is present in breast milk, but at the time of writing no reports of its use in nursing mothers have been located.
