Based on PubMed | Can atorvastatin cause numbness or tingling in the hands or feet, and when should I seek medical attention for it?

Atorvastatin can, in rare cases, be linked to numbness or tingling in the hands or feet, because statins have been associated with peripheral neuropathy (nerve irritation or damage). ^[1] This effect is uncommon, but it is listed among nervous system side effects for atorvastatin, alongside symptoms like dizziness. ^[2]

What’s happening

• Possible peripheral neuropathy: Statin‑associated neuropathy may feel like pins and needles, burning, reduced sensation, or electric‑shock sensations, typically starting in the toes or fingers. ^[1] Although most people never develop this problem, it is recognized in official product information for atorvastatin. ^[2]

How common is it

• Uncommon overall, possibly modestly increased risk: Large safety summaries consider peripheral neuropathy a rare adverse effect with statins. ^[3] Observational analyses have found a modest association between statin use and peripheral neuropathy after adjusting for other risks, though they cannot prove cause and effect. ^[4] Clinically, most users never experience neuropathy, and benefits for heart and stroke prevention are well established. ^[3]

When to seek medical attention

• Contact your clinician promptly if:

  • Numbness or tingling is new, persistent, worsening, or spreading (for example, moving up from toes to feet or beyond). ^[5]
  • You also notice weakness, trouble walking, balance problems, or burning pain. ^[5]
  • Symptoms start soon after a dose increase or a new medication was added that could interact with your statin. ^[6]
  • You have risk factors for neuropathy (such as diabetes, vitamin B12 deficiency, heavy alcohol use), since you may need evaluation regardless of the statin. ^[4]

• Urgent care is advised if numbness or weakness is sudden and one‑sided, facial droop, trouble speaking, or severe sudden headache occur, because these can be signs of stroke and need emergency evaluation. ^[5]

What your clinician might do

• Assess and rule out other causes: Diabetes, thyroid disease, vitamin B12 deficiency, spinal problems, and alcohol can cause similar symptoms, so basic labs and a neurological exam may be considered. ^[4]
• Medication review and adjustments: Your clinician may consider a brief pause of the statin, a dose reduction, changing to a different statin, or timing changes to see if symptoms improve, done under medical supervision. ^[7] If symptoms resolve after stopping and return with re‑challenge, that supports a medication side effect. ^[7]
• Symptom management: If neuropathy is confirmed, supportive measures and, if needed, neuropathic pain treatments may be discussed. ^[8]

Practical self‑check steps

• Track onset and pattern: date started, which areas are affected, whether it is constant or intermittent, and any triggers. ^[5]
• List all medicines and supplements, including antibiotics, antifungals, antivirals, and immunosuppressants that may interact with statins, and share with your clinician. ^[6]
• Do not stop atorvastatin on your own; discuss any side effects before making changes, because the medication lowers heart and stroke risk. ^[5]

Key takeaways

• Yes, atorvastatin can rarely cause numbness or tingling due to peripheral neuropathy. ^[1] This is uncommon, but recognized in official prescribing information. ^[2]
• Tell your clinician if you notice new or worsening numbness or tingling, especially if it persists, spreads, or comes with weakness or balance trouble. ^[5]
• Never stop a statin without medical guidance; many side effects can be managed by dose adjustment or switching medicines while still protecting your heart. ^{[5] [7]}

Table: When to seek care for numbness or tingling while on atorvastatin

• New, persistent, or worsening numbness/tingling in hands or feet → Contact clinician within a few days. ^[5]
• Symptoms with weakness, balance trouble, or burning pain → Contact clinician promptly (soon). ^[5]
• Sudden one‑sided weakness, facial droop, speech trouble → Call emergency services immediately. ^[5]
• After a dose increase or new interacting drug added → Contact clinician to review medications. ^[6]
