Are amoxicillin and atorvastatin safe to take at the same time?
Amoxicillin and atorvastatin can generally be taken together. They are used for different purposes—amoxicillin is an antibiotic for bacterial infections, and atorvastatin helps lower cholesterol—and there is no well-known, clinically important drug–drug interaction between them.
What side effects should you watch for when combining them?
If you take both at the same time, monitor for side effects from either medication:
- From amoxicillin: diarrhea, nausea, stomach upset, rash, or yeast overgrowth. Get urgent care for signs of an allergic reaction (hives, swelling of lips/face, trouble breathing).
- From atorvastatin: muscle pain or weakness, dark urine, unusual fatigue, or liver-related symptoms (yellowing of skin/eyes, severe nausea/vomiting). Seek prompt medical advice for muscle symptoms.
If you feel significantly worse after starting either medicine, contact a clinician.
Do food, timing, or missed doses change anything?
- Amoxicillin can usually be taken with or without food, but follow the label or your prescription instructions.
- Atorvastatin is commonly taken once daily, and taking it at the same time each day can help you stay consistent.
- Missing doses: take the missed dose when you remember unless it’s close to the next dose; don’t double up.
When would you want to check with a clinician first?
Check with a pharmacist or prescriber before taking them together if you have:
- A history of serious penicillin allergy (for amoxicillin)
- Prior statin-related muscle problems
- Significant liver disease
- Other medications that raise atorvastatin exposure (for example, certain antifungals, some antibiotics, HIV medicines, or cyclosporine), since those can increase statin-related side effects
What about other antibiotics or cold medicines?
If you’re being treated for an infection, tell your prescriber/pharmacist about everything you take, including OTC cold medicines, supplements, or additional antibiotics. The interaction risk depends on the full medication list, not just amoxicillin plus atorvastatin.
