    Oral solution contains glycerol
    Some formulations contain castor oil polyoxyl which may cause diarrhoea
    Autoimmune disorders can occur many months after initiation of treatment
    Blood lipid and glucose levels may increase requiring treatment
    Consider monitoring ECG in patients at risk of QT prolongation
    Monitor patient closely for signs and symptoms of toxicity
    Monitor patients with decreased ability to metabolise propylene glycol

    Inflammatory symptoms should be evaluated and treated appropriately
    Risk of developing opportunistic infections
    Discontinue if hepatic function deteriorates in pts with hepatic impairment
    Advise patient not to take St John's wort concurrently
    Female: Barrier or non-hormonal contraception advised during treatment
    Advise haemophiliac patients of possibility of increased bleeding

    Modest asymptomatic prolongation of the PR interval has been observed in some healthy adult subjects. Rare reports of 2nd or 3rd degree atrioventricular block in patients with underlying structural heart disease and pre-existing conduction system abnormalities or in patients also receiving drugs known to prolong the PR interval have been reported. Lopinavir with ritonavir should therefore be used with caution in such patients.

    Blood lipid and glucose levels may increase during antiretroviral therapy. This may be linked to disease control and lifestyle. Refer to established HIV treatment guidelines for monitoring and manage lipid and glucose level disorders as appropriate.

    The oral solution contains alcohol (42% v/v), which is potentially harmful to those suffering from hepatic disease, alcoholism, epilepsy, brain injury or brain disease as well as for children and pregnant women. It may modify or increase the effects of other medicines.

    Oral solution contains propylene glycol. Patients with hepatic impairment and decreased ability to metabolise propylene glycol (e.g asian ancestry) should be monitored for potential adverse reactions related to propylene glycol toxicity (i.e. seizures, stupor, tachycardia, hyperosmolarity, lactic acidoses, renal toxicity, haemolysis).

    Attention should be paid to the total amounts of alcohol and propylene glycol given to infants in order to avoid toxicity from these excipients. Infants should be monitored closely for any signs of toxicity.

    Pregnancy and Lactation

    Pregnancy

    Lopinavir with ritonavir oral solution is contraindicated during pregnancy.

    The manufacturer states that the prevalence of birth defects in newborns exposed to lopinavir with ritonavir in any trimester is comparable to the general population and contraindicates the use of the oral solution formulation of lopinavir with ritonavir during pregnancy due to potential risk of toxicity from the excipient propylene glycol. Oral solid formulations are available as an alternative.

    Animal studies have shown reproductive toxicity, with Briggs (2015) suggesting a moderate risk in human pregnancy but concluding that the drug should not be withheld because of pregnancy if clinically necessary.

    Lactation

    Lopinavir with ritonavir is contraindicated in breastfeeding women. It is recommended that HIV infected women do not breast feed their infants in order to avoid transmission of HIV.

    It is not known whether this medicinal product is excreted in human milk; little data are available on the use of lopinavir in combination with ritonavir in breastfeeding. Animal studies suggest the drug is excreted in the milk. Use in breastfeeding is contraindicated by the manufacturer.

    The molecular weight of lopinavir and ritonavir combined, together with their lipid solubility, suggests that the drugs will be excreted in human breast milk, but that high protein binding should limit this excretion (Briggs 2015).
