What Are the Long-Term Side Effects of Rosuvastatin?

Rosuvastatin, commonly known under its brand name “Crestor,” belongs to a class of medications known as statins. Statins are prescribed to lower blood cholesterol levels and reduce the risk of cardiovascular diseases. However, as with any medication, rosuvastatin may come with its share of side effects, especially when taken long term.

1. Cognitive Impairments: A Memory Concern?

A study led by L. Galatti in 2006 shed light on an intriguing aspect: the potential association of rosuvastatin with memory loss and cognitive impairments. Some patients reported instances of forgetfulness, confusion, and difficulty concentrating. Although not common, these symptoms can be distressing and warrant further investigation.

2. The Peripheral Nervous System: A Neuropathic Perspective

Peripheral neuropathy, characterized by numbness, tingling, or pain in the hands and feet, is a potential side effect associated with statin use. A 2019 study by I.H. Özdemir explored this in-depth, highlighting that long-term use of rosuvastatin might increase the risk of this condition.

3. Renal and Hepatic Insights: Safety Profile

According to a 2007 study by R.M. Guthrie, concerns regarding kidney function in relation to long-term statin use were alleviated. The study indicated that rosuvastatin, unlike some other drugs, does not contribute to a decline in renal function. Moreover, its effect on the liver showed a fairly safe profile, although regular monitoring of liver enzymes is always advised when on statin therapy.

4. Muscular Complaints: A Legitimate Concern

Statins, including rosuvastatin, have been linked with muscle pain and weakness, with some severe cases resulting in a condition called rhabdomyolysis. The study by M.C. Baggett in 2020 emphasized this aspect, as the pain subsided after discontinuation of the drug but returned upon re-administration.

5. Endocrine Interactions: Diabetes Connection

An often-debated point in medical literature is the association of statins with diabetes. J.G. Robinson’s 2015 study showed that high-intensity statins, like rosuvastatin, might be linked with a slightly higher risk of diabetes compared to moderate-intensity statins.

6. Eye Health: The Glaucoma Link

A 2023 study by Y. Yuan brought attention to a noteworthy observation. Long-term statin use was found to be potentially linked with an elevated risk of glaucoma onset, a condition that affects the optic nerve of the eye and can lead to vision loss.

Supplementary Care: Vitamins and Rosuvastatin

When it comes to vitamins, it’s essential to be cautious about potential interactions. Although not a side effect per se, certain vitamins may interfere with rosuvastatin’s effectiveness. Patients are often advised to consult their healthcare provider before combining any vitamin supplements with their medication.


While rosuvastatin is an effective and widely prescribed medication, it is crucial to be aware of and monitor potential side effects, especially with long-term use. Regular check-ups and open communication with healthcare professionals can ensure that the benefits of the drug outweigh its risks.

FAQs about Rosuvastatin’s Long-term Side Effects

Q1: How does rosuvastatin potentially affect liver function in the long run?

Answer: While rosuvastatin is generally deemed safe for the liver, some patients might experience a rise in liver enzymes. This can indicate potential liver inflammation or damage. Though these elevations are typically mild and temporary, in rare cases, they can signify serious liver problems. Regular monitoring of liver enzymes through blood tests is crucial, especially in the first few months after initiating therapy.

Q2: What are the implications of rosuvastatin on kidney function over extended periods?

Answer: Contrary to some apprehensions, research suggests that rosuvastatin does not cause a decline in kidney function. In fact, it may even have renoprotective effects in certain populations. However, as with liver function, regular check-ups are vital to ensure the kidneys remain unaffected.

Q3: Is there any link between rosuvastatin and mood changes or depression?

Answer: Currently, the literature does not strongly support a direct correlation between rosuvastatin use and mood alterations, including depression. However, some patients have reported mood swings or feelings of depression. It’s essential for patients to discuss any mood changes with their healthcare providers, as multiple factors could contribute to these symptoms.

Q4: Are there specific age-related concerns regarding the use of rosuvastatin for older adults?

Answer: Older adults may be more susceptible to muscle pain or weakness, a known side effect of statins. Furthermore, since kidney function tends to decline with age, elderly patients may also require dosage adjustments and frequent monitoring to prevent potential drug accumulation and associated side effects.

Q5: Can rosuvastatin impact sexual health?

Answer: A study by Z. Nurkalem in 2014 explored the effects of rosuvastatin and atorvastatin on erectile function. The results indicated that while atorvastatin might increase erectile dysfunction, rosuvastatin showed no such effect. However, as individual responses to medications can vary, any concerns in this area should be discussed with a healthcare provider.

Q6: Are there any dermatological side effects linked with prolonged rosuvastatin use?

Answer: While not common, some patients on rosuvastatin have reported skin reactions, including rashes, itching, and hives. In very rare instances, a more severe skin reaction known as Stevens-Johnson syndrome has been documented. It’s essential to seek medical attention if any unusual skin changes occur.

Q7: How might rosuvastatin interact with other medications when used long term?

Answer: Rosuvastatin can interact with several medications, affecting its metabolism and thereby altering its effectiveness and safety. Drugs such as anticoagulants, certain antiviral medications, and other cholesterol-lowering agents may interact with rosuvastatin.
