About Vonoprazan + Amoxicillin + Clarithromycin
Indications of Vonoprazan + Amoxicillin + Clarithromycin
Established / FDA-Approved Use
Vonoprazan + Amoxicillin + Clarithromycin is indicated for the treatment (eradication) of Helicobacter pylori (H. pylori) infection in adults, given as a fixed 14-day combination course.
Important Limitations
- Vonoprazan + Amoxicillin + Clarithromycin is not indicated for the treatment of gastroesophageal reflux disease (GERD), peptic ulcer disease, or other acid-related conditions on its own — it is specifically an H. pylori eradication regimen.
- Regional clarithromycin resistance rates in H. pylori strains affect the expected success of this regimen; where resistance is high, or after a prior failed eradication attempt, a physician may choose an alternative (e.g., bismuth-based quadruple) regimen instead.
- Use of Vonoprazan + Amoxicillin + Clarithromycin when infection is not proven or strongly suspected does not provide benefit and increases the risk of drug-resistant bacteria.
Dosage & Administration of Vonoprazan + Amoxicillin + Clarithromycin
Standard Adult Regimen (H. pylori eradication)
| Time | Vonoprazan | Amoxicillin | Clarithromycin |
|---|---|---|---|
| Morning | 20 mg | 1,000 mg | 500 mg |
| Evening | 20 mg | 1,000 mg | 500 mg |
The full course of Vonoprazan + Amoxicillin + Clarithromycin is taken twice daily for a fixed duration (typically 14 days, per physician's prescription), with or without food. All three components must be taken together at each dosing time.
Missed Dose
If a dose of Vonoprazan + Amoxicillin + Clarithromycin is missed, take it as soon as possible within 4 hours of the scheduled time. If more than 4 hours have passed, skip the missed dose and resume the normal dosing schedule — do not double the next dose.
Renal and Hepatic Impairment
- Renal impairment: Use of Vonoprazan + Amoxicillin + Clarithromycin is not recommended in patients with severe renal impairment (creatinine clearance below 30 mL/min).
- Hepatic impairment: Use is not recommended in patients with moderate to severe hepatic impairment (Child-Pugh Class B or C).
Antibiotic Stewardship
Take Vonoprazan + Amoxicillin + Clarithromycin exactly as prescribed by your physician; do not stop, extend, skip doses, or share this medicine with others without medical advice. Completing the full prescribed course is essential for successful H. pylori eradication and to limit the development of antibiotic resistance.

Frequently Asked Questions about Vonoprazan + Amoxicillin + Clarithromycin
What is Vonoprazan + Amoxicillin + Clarithromycin used for?
Vonoprazan + Amoxicillin + Clarithromycin is used as a 14-day combination course to eradicate Helicobacter pylori (H. pylori) infection in adults. It is not intended for long-term use for acid reflux or other stomach acid conditions alone.
How should I take Vonoprazan + Amoxicillin + Clarithromycin?
Take all three components of Vonoprazan + Amoxicillin + Clarithromycin together, twice daily (morning and evening), for the full number of days prescribed by your physician, with or without food. Complete the entire course even if you feel better sooner, and never skip, stop, extend, or share doses without medical advice.
Can I take Vonoprazan + Amoxicillin + Clarithromycin if I am allergic to penicillin?
No. A known allergy to penicillin or other beta-lactam antibiotics is an absolute contraindication to Vonoprazan + Amoxicillin + Clarithromycin because it contains amoxicillin. Tell your physician about any drug allergies so an alternative, penicillin-free eradication regimen can be prescribed.
Is Vonoprazan + Amoxicillin + Clarithromycin safe during pregnancy or breastfeeding?
Vonoprazan + Amoxicillin + Clarithromycin is not recommended during pregnancy except when no alternative therapy is appropriate and a physician determines the benefit outweighs the potential risk to the fetus, since clarithromycin has been linked to increased miscarriage risk in some studies. During breastfeeding, small amounts of amoxicillin and clarithromycin pass into breast milk and may affect the infant's digestion; use only if your physician advises it, with the infant monitored for diarrhea or rash.
What side effects should I watch for while taking Vonoprazan + Amoxicillin + Clarithromycin?
Common side effects include altered taste, diarrhea, vaginal yeast infection, headache, abdominal pain, and increased blood pressure. Seek medical care promptly for severe or bloody diarrhea, irregular heartbeat, yellowing of the skin/eyes, or signs of a serious allergic reaction (rash, swelling of the face/throat, difficulty breathing) while taking Vonoprazan + Amoxicillin + Clarithromycin.
What if I miss a dose of Vonoprazan + Amoxicillin + Clarithromycin?
If you miss a dose, take it as soon as possible within 4 hours of the scheduled time. If more than 4 hours have passed, skip that dose and continue with your normal schedule — do not double up doses of Vonoprazan + Amoxicillin + Clarithromycin.
