Can you take atorvastatin and hydrochlorothiazide together?
Yes. Atorvastatin (a statin) and hydrochlorothiazide (a thiazide diuretic) are commonly used together because they treat different conditions and do not have a known incompatibility when taken as prescribed.
Are there drug interactions between them?
No specific, clinically significant interaction between atorvastatin and hydrochlorothiazide is indicated in the information provided here. In practice, these two medicines are often co-prescribed for people who need both blood-pressure control and cholesterol lowering.
What side effects should you watch for if you take both?
When used together, the main concerns are usually side effects from each drug individually:
- From hydrochlorothiazide: it can lower potassium and sodium and may raise uric acid and blood sugar in some people.
- From atorvastatin: it can rarely cause muscle aches and, very rarely, more serious muscle injury.
If you develop severe or persistent muscle pain/weakness, dark urine, fainting, or significant weakness (especially with dizziness), contact a clinician promptly.
What should you tell your clinician before starting (or combining) them?
Tell your clinician if you have:
- Kidney problems or history of electrolyte problems (low potassium, low sodium)
- Diabetes or prediabetes
- A history of muscle injury with statins
- Liver disease or heavy alcohol use
- Any other medicines or supplements you take (including NSAIDs, potassium supplements, or other blood-pressure drugs)
What monitoring is typical?
Clinicians often monitor:
- Blood pressure response
- Blood tests for electrolytes (especially potassium) with hydrochlorothiazide
- Liver-related testing and cholesterol response with atorvastatin (per usual care)
When to get urgent help
Get urgent medical care if you have signs of serious statin muscle injury (severe muscle pain with weakness, fever, or dark urine) or symptoms of dangerously low electrolytes (severe confusion, fainting, or irregular heartbeat).
