Dehydration, low blood pressure, blood sugar changes, inner-ear disorders, cardiovascular problems, and other medications can all contribute.
If dizziness is persistent, severe, or associated with fainting, chest pain, difficulty breathing, or neurological symptoms, seek medical evaluation.
13. Memory or Cognitive Symptoms
You may see dramatic claims online that statins cause permanent memory loss or dementia.
The evidence is much more nuanced.
Some people have reported temporary memory or concentration problems while taking statins, and regulatory agencies have acknowledged that such reports can occur. These reports are generally uncommon and typically reversible after stopping or changing the medication.
At the same time, large studies have not established that statins cause dementia, and research has not demonstrated a general harmful effect on cognition.
If you notice a significant new cognitive change, discuss it with your clinician rather than assuming the cause.
14. Drug Interactions
One of the most important issues isn't technically a side effect—it is interaction with other substances.
Atorvastatin can interact with certain medications, and some interactions can increase the risk of muscle toxicity.
Certain antibiotics, antifungal medications, antiviral drugs, and other medicines may affect how atorvastatin is metabolized.
Grapefruit and grapefruit juice can also interact with atorvastatin, particularly in larger amounts, because grapefruit compounds can affect the enzyme responsible for metabolizing the medication.
Always tell your healthcare professional about prescription medications, over-the-counter drugs, and supplements you take.
15. Serious Symptoms Should Never Be Ignored
Most people taking atorvastatin will not experience severe complications.
But certain symptoms deserve prompt medical attention.
Contact a healthcare professional urgently if you develop:
Severe or unexplained muscle pain or weakness
Dark-colored urine
