Rabeprazole + Amoxicillin + Clarithromycin: Brands, Price & Uses in Bangladesh

Rabeprazole + Amoxicillin + Clarithromycin is a co-packaged fixed combination (proton pump inhibitor plus two antibiotics) indicated for the eradication of Helicobacter pylori (H. pylori) infection, typically prescribed together with confirmed or strongly suspected active or past peptic ulcer disease (gastric or duodenal ulcer). Its use is classified below by strength of evidence:

• Established/guideline-supported use: First-line triple therapy for H. pylori eradication in patients with peptic ulcer disease, in regions/populations with low clarithromycin resistance, per international consensus guidelines (e.g., ACG, Maastricht/Florence consensus, WHO-aligned national guidance).
• Combination-dependent use: Each component alone is insufficient for eradication; Rabeprazole + Amoxicillin + Clarithromycin works only as the complete three-drug regimen taken together — omitting or substituting any one component reduces eradication rates and promotes antibiotic resistance.
• Adjunct rationale: The rabeprazole component raises intragastric pH, which improves the antibacterial activity and stability of amoxicillin and clarithromycin and also promotes ulcer healing during therapy.

Rabeprazole + Amoxicillin + Clarithromycin is not intended for use as acid-suppression monotherapy, for uninvestigated dyspepsia without confirmed H. pylori infection, or for treatment of infections other than H. pylori.

H. pylori Eradication (Adults)

All three components of Rabeprazole + Amoxicillin + Clarithromycin are taken together at approximately the same two times each day (e.g., morning and evening), generally before meals for the rabeprazole component, as directed by the prescribing physician. The exact duration (commonly 7, 10, or 14 days depending on local resistance patterns and physician judgment) should follow the prescriber's instructions and local treatment guidelines.

Renal Impairment

No dose adjustment of rabeprazole or clarithromycin is generally required in mild-to-moderate renal impairment; amoxicillin dosing interval may need adjustment in significant renal impairment (see Use in Special Populations).

Hepatic Impairment

Rabeprazole + Amoxicillin + Clarithromycin should be used with caution and under close physician supervision in hepatic impairment; it is not recommended in severe hepatic impairment (see Contraindications and Use in Special Populations).

Patients must take Rabeprazole + Amoxicillin + Clarithromycin exactly as prescribed by their physician; do not stop, extend, skip doses, or share this medicine with others without medical advice, as incomplete courses reduce the chance of successful eradication and promote antibiotic resistance.

Common side effects reported with Rabeprazole + Amoxicillin + Clarithromycin include:

• Diarrhea, loose stools, nausea, abdominal pain
• Taste disturbance (metallic/bitter taste, common with clarithromycin)
• Headache
• Vaginal candidiasis or oral thrush (antibiotic-related)

Less common but serious effects requiring prompt medical attention:

• Clostridioides difficile-associated diarrhea/colitis, which can range from mild to life-threatening and may occur during or up to several weeks after therapy
• Severe allergic reactions, including rash, urticaria, angioedema, or anaphylaxis (amoxicillin)
• QT-interval prolongation and, rarely, serious ventricular arrhythmia (clarithromycin)
• Hepatotoxicity/abnormal liver function, including rare cholestatic jaundice
• Severe cutaneous reactions (e.g., Stevens-Johnson syndrome, toxic epidermal necrolysis) – rare

Patients should seek immediate medical attention for severe or persistent diarrhea, signs of an allergic reaction, palpitations/fainting, or yellowing of the skin or eyes while taking Rabeprazole + Amoxicillin + Clarithromycin.
