pravastatin pitavastatin

Applies to: pravastatin and pitavastatin

MONITOR: The risk of peripheral neuropathy may be increased during concurrent use of two or more agents that are associated with this adverse effect. Patient risk factors include diabetes and age older than 60 years. In some cases, the neuropathy may progress or become irreversible despite discontinuation of the medications.

MANAGEMENT: Caution is advised during concomitant use of agents with neurotoxic effects. Patients should be monitored closely for symptoms of neuropathy such as burning, tingling, pain, or numbness in the hands and feet. Since the development of peripheral neuropathy may be dose-related for many drugs, the recommended dosages should generally not be exceeded. Consideration should be given to dosage reduction or immediate discontinuation of these medications in patients who develop peripheral neuropathy to limit further damage. If feasible, therapy should generally be reinstituted only after resolution of neuropathy symptoms or return of symptoms to baseline status. In some cases, permanent dosage reductions may be required.

Applies to: pravastatin

MONITOR: Concomitant use of statin medication with substantial quantities of alcohol may increase the risk of hepatic injury. Transient increases in serum transaminases have been reported with statin use and while these increases generally resolve or improve with continued therapy or a brief interruption in therapy, there have been rare postmarketing reports of fatal and non-fatal hepatic failure in patients taking statins. Patients who consume substantial quantities of alcohol and/or have a history of liver disease may be at increased risk for hepatic injury. Active liver disease or unexplained transaminase elevations are contraindications to statin use.

MANAGEMENT: Patients should be counseled to avoid substantial quantities of alcohol in combination with statin medications and clinicians should be aware of the increased risk for hepatotoxicity in these patients.

Therapeutic duplication warnings

Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition. This can be intentional in cases where drugs with similar actions are used together for demonstrated therapeutic benefit. It can also be unintentional in cases where a patient has been treated by more than one doctor, or had prescriptions filled at more than one pharmacy, and can have potentially adverse consequences.

Duplication

Hmg co-a reductase inhibitors

Therapeutic duplication

The recommended maximum number of medicines in the 'HMG Co-A reductase inhibitors' category to be taken concurrently is usually one. Your list includes two medicines belonging to the 'HMG Co-A reductase inhibitors' category:

  • pitavastatin
  • pravastatin

Note: In certain circumstances, the benefits of taking this combination of drugs may outweigh any risks. Always consult your healthcare provider before making changes to your medications or dosage.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
