Camphor and Pravastatin Sodium

Here is the interaction we found between these two, with the evidence behind it.

Moderate

HEPATOTOXIC DRUGS

Why this applies to Pravastatin Sodium

Pravastatin Sodium falls under HEPATOTOXIC DRUGS — the group Camphor interacts with.

Theoretically, concomitant use of camphor with other hepatotoxic drugs might increase the risk of liver damage.
There have been a few case reports of transient elevations in liver enzymes in adults after oral or topical use of camphor. There has also been one case of hepatotoxicity in an infant after topical camphor use.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist of this one: both camphor and pravastatin (Pravachol) are processed by your liver, and there's a thought that putting two things through the liver that can stress it might add up. With pravastatin, liver-related side effects are uncommon but recognized, things like elevated liver enzymes that your doctor watches for on bloodwork. Camphor has only rarely been linked to brief enzyme bumps, mostly after it was swallowed (which you should never do) or in a few topical cases.

Honestly, this is a theoretical concern, not something proven to happen often. Using a camphor rub on your skin for sore muscles while taking pravastatin is very unlikely to cause a problem. Just never take camphor by mouth, and let your pharmacist or doctor know if you notice yellowing skin, dark urine, or unusual fatigue.

About Camphor

What is Camphor?

  • Muscle and joint aches
  • Cough and chest congestion
  • Itching and skin irritation
  • Cold sores or minor wounds
  • Counterirritant for pain

Camphor is a strong-smelling compound from the camphor tree (or made synthetically) that is used in many topical rub-on products for muscle aches, itching, and chest congestion. It can be helpful for these uses when applied to the skin in small, regulated amounts, but it is toxic and potentially deadly if swallowed, so it should never be taken by mouth. Keep camphor products away from children and check with a pharmacist before use.

About Pravastatin

What Is Pravastatin Used For?

Brand name: Pravachol

Pravastatin Sodium tablets are used alongside a cholesterol-lowering diet to treat high LDL cholesterol (bad cholesterol), high triglycerides (blood fats), and abnormal cholesterol levels. They are approved for adults and for children ages 8 and older with a hereditary form of high cholesterol called heterozygous familial hypercholesterolemia (HeFH).

In people without known heart disease, pravastatin helps reduce the risk of heart attack and cardiovascular death. In people who already have coronary heart disease (CHD), it is used to reduce the risk of heart attack, coronary death, stroke, transient ischemic attack (TIA), and procedures to restore blood flow to the heart — and to slow the buildup of plaque in the arteries.
