Interactions of Zocor: Other drugs, alcohol, and additional substances to consider
Zocor, a popular oral tablet used to lower cholesterol and triglyceride levels, and reduce certain heart-related risks, can interact with several substances, including medications, supplements, and even certain foods [1]. Understanding these potential interactions is crucial for ensuring the safe and effective use of Zocor.
One class of medications that may interact with Zocor are Calcium Channel Blockers (CCBs). Examples include amlodipine, diltiazem, verapamil, and nicardipine. CCBs may slow the activity of an enzyme that helps break down Zocor in your body, causing Zocor to build up in your system. This can increase the risk of side effects, such as severe muscle weakness and rhabdomyolysis [1].
Another potential interaction involves the use of colchicine and Zocor. These drugs may increase the risk of muscle problems when taken together [1].
Zocor is metabolized by cytochrome P450 enzymes, particularly CYP3A4. Substances like cannabis and cannabidiol (CBD) can inhibit these enzymes, potentially increasing the blood levels of statins like simvastatin, and increasing the risk of side effects such as muscle damage or liver problems [2]. However, there are no specific reports of interactions between Zocor and cannabis or CBD [1].
Other drugs and supplements that may interact with Zocor include nefazodone, danazol, cyclosporine, colchicine, cobicistat, warfarin, certain antifungals, certain antibiotics, certain antivirals, and fibrates. These interactions can increase the risk of side effects [1].
It's important to note that while there are no specific reports of vitamins interacting with Zocor, it's still advisable to discuss any vitamin product with your doctor or pharmacist before taking it with Zocor [1].
Grapefruit and grapefruit juice may also interact with Zocor, leading to a higher level of Zocor in your body and increasing your risk of side effects [1].
Zocor may not interact with vaccines or lab tests, but it's always a good idea to discuss any concerns with your doctor [1].
People of Chinese ancestry may have a higher risk of muscle problems with Zocor, so it's important to discuss this with your doctor before starting treatment [1]. If you have an underactive thyroid, kidney failure, or alcohol-related liver disease, you should talk with your doctor before taking Zocor, as these conditions may increase your risk of side effects from the drug [1].
Zocor is contraindicated in people with certain liver conditions, such as acute liver failure and decompensated cirrhosis. It's also contraindicated in people taking certain drugs that increase the risk of Zocor's side effects, such as nefazodone, cobicistat, certain antifungals, certain antibiotics, certain antivirals, danazol, cyclosporine, and gemfibrozil [1].
Older adults (age 65 years or older) may have a higher risk of muscle problems with Zocor, so your doctor may prescribe you a lower dosage than is typical [1]. Zocor may interact with red yeast rice supplements, increasing the risk of muscle problems as a side effect [1].
Your doctor may advise you to avoid or limit alcohol consumption during Zocor treatment due to the risk of liver damage, although there aren't any known interactions between Zocor and alcohol [1]. Zocor is contraindicated in people who have had an allergic reaction to Zocor or any of its ingredients [1].
In summary, while there are no direct, confirmed interactions between Zocor and cannabis or CBD, CBD can inhibit liver enzymes (CYP450) that metabolize simvastatin, potentially raising simvastatin levels. This may increase risks of adverse effects from Zocor. Always discuss cannabis or CBD use with your doctor when on Zocor to monitor for side effects and adjust medication if needed [1]. If your doctor prescribes Zocor with a CCB, they may prescribe a lower Zocor dosage to help reduce the risk of side effects [1].

- Science reveals that Calcium Channel Blockers (CCBs) like amlodipine, diltiazem, verapamil, and nicardipine, may interact with Zocor, potentially slowing the activity of an enzyme that helps break down Zocor, leading to a risk of side effects such as severe muscle weakness and rhabdomyolysis.
- In addition to CCBs, the use of colchicine and Zocor together may increase the risk of muscle problems.
- Zocor is metabolized by cytochrome P450 enzymes, and while there are no specific reports of interactions between Zocor and cannabis or CBD, CBD can inhibit these enzymes, potentially increasing the blood levels of statins like simvastatin, and increasing the risk of side effects such as muscle damage or liver problems.
