Oral formulations containing acipimox
Hyperlipidaemia type IIa, IIb and IV
Alternative or adjunct treatment to reduce triglyceride levels in patients who have not responded adequately to other treatments for: a) Hypercholesterolaemia and hypertriglyceridaemia (Fredrickson type IIb hyperlipoproteinaemia)
b) Hypertriglyceridaemia (Fredrickson type IV hyperlipoproteinaemia) Acipimox should be used only after other lipid-lowering measures have been taken, such as dietary and lifestyle changes.
Daily dosage should be adjusted individually depending on plasma triglyceride and cholesterol levels. Improvements are usually seen after the first month of treatment.
Type IV Hyperlipoproteinaemias
250 mg twice daily
Type IIA and IIB hyperlipoproteinaemias
250 mg three times daily
Daily dosages of up to 1200 mg have been safely administered for long periods.
(See Dosage; Adult)
Patients with Renal Impairment
For patients with creatinine clearance values between 30 to 60 ml/minute, the dose needs to be reduced to 250 mg 1 or 2 times daily. It is advised that longer intervals are left between doses of the drug in patients with renal impairment.
Accumulation should be expected as acipimox is eliminated entirely through the kidneys. Accumulation is dependent on the level of renal impairment.
Children under 18 years
Renal impairment - creatinine clearance below 30 ml/minute
Precautions and Warnings
Renal impairment - creatinine clearance 30-60ml/minute
Reduce dose in patients with creatinine clearance of 30-60ml/min
Monitor hepatic function
Monitor renal function
Dietary restrictions should be maintained
Pregnancy and Lactation
Acipimox is contraindicated during pregnancy.
Acipimox has not been studied sufficiently in human pregnancy for safety to be established. Schaefer (2015) concludes that this lipid reducers should not be used during pregnancy because their safety has not been established
There is no evidence from animal studies to show that acipimox is teratogenic, however a higher incidence of immature and underweight foetuses was seen when higher doses of acipimox were given.
The use of all medication in pregnancy should be avoided whenever possible; particularly in the first trimester. Non-drug treatments should also be considered. When essential, a medication with the best safety record over time should be chosen, employing the lowest effective dose for the shortest possible time. Polypharmacy should be avoided. Teratogens taken in the pre-embryonic period, often quoted as lasting until 14 to 17 days post-conception, are believed to have an all-or-nothing effect. Where drugs have a short half-life, and when the date of conception is certain, this may allow women to be reassured where drug exposure has occurred within this time frame.

Acipimox is contraindicated during breastfeeding.
As there is limited animal data regarding the levels of acipimox excreted in milk, the manufacturer recommends that acipimox is not used during breastfeeding.
Neonates, infants born prematurely, those with low birth weight, those with an unstable gastrointestinal function or who have serious illnesses may require special consideration. For any infant, if a drug is prescribed to the nursing mother, it should be at the lowest practical dose and for the shortest time. When drug administration is unavoidable and breastfeeding is to continue, minimisation of exposure of the infant to the drug may sometimes be achieved by timing the maternal doses to just after a feeding episode. Infants exposed to drugs via breast milk should be monitored for unusual signs or symptoms. Interactions between the drug received by the infant from the mother's milk and medication prescribed for the infant should also be considered, for example, when the drug given to the infant may prevent metabolism of the drug received via breast milk.
