PTCB Certified Pharmacy Technician (PTCE)MedicationsMedium
A patient calls the pharmacy reporting they have been experiencing severe muscle pain and weakness since starting 'rosuvastatin 20 mg daily' a few weeks ago. Which of the following conditions is the most serious potential adverse effect associated with statins that the technician should be concerned about?
- AConstipation
- BRhabdomyolysis
- CInsomnia
- DHeadache
Show answer & explanationAnswer & explanation
Correct answer: B. Rhabdomyolysis
Rosuvastatin is a statin, a class of drugs known to cause muscle-related side effects. While mild myalgia is common, severe muscle pain and weakness can be a symptom of rhabdomyolysis, a rare but life-threatening condition involving muscle breakdown and potential kidney damage. This requires immediate medical attention.
Why the other options are wrong
- A. Constipation is a possible side effect of various medications but not a primary or severe concern for statins.
- C. Insomnia is not a primary or severe adverse effect associated with statin therapy.
- D. Headache is a common, generally mild side effect of many drugs, not specific to severe statin toxicity.
Statin-Induced Rhabdomyolysis
A rare but serious adverse effect of statin medications characterized by rapid breakdown of skeletal muscle tissue, leading to the release of muscle proteins (like myoglobin) into the bloodstream, which can cause kidney damage.
- Symptoms include severe muscle pain, weakness, dark urine.
- Requires immediate medical attention.
- Risk factors include high statin doses, drug interactions, and certain medical conditions.
Memory trick: Statins lower 'Cholesterol', but watch for 'Muscle Pain' and 'Kidney Trouble'.
