Drug pricing is set separately in each country through different negotiation, regulatory, and distribution systems, so the same medication can legitimately carry different price tags on either side of the border.

Clarithromycin ER is the generic name for this extended-release antibiotic. It is manufactured by several companies, including Apotex Corp., Lannett Company, Inc., and Par Pharmaceutical, Inc. The original brand-name versions, which contain the same active ingredient, are Biaxin and Biaxin XL.

Clarithromycin ER is an extended-release macrolide antibiotic used to combat bacterial infections of the skin and respiratory tract. It is also part of combination therapy to eradicate Helicobacter pylori, a bacteria linked to stomach ulcers. The medication works by killing bacteria and stopping their growth. It is crucial to finish the entire prescribed course, even if symptoms improve, to prevent antibiotic resistance. This drug does not treat viral infections like colds or flu. Before starting treatment, inform your doctor of any history of heart conditions (especially long QT syndrome or coronary artery disease), myasthenia gravis, liver or kidney disease, diabetes, or electrolyte imbalances. Clarithromycin ER is not recommended during pregnancy as it may harm the fetus; effective contraception is advised during treatment.

Common side effects of this antibiotic include stomach pain, nausea, vomiting, diarrhea, and an unusual taste. However, more serious reactions require immediate medical attention. Stop taking the medication and contact your doctor if you experience severe stomach pain, watery or bloody diarrhea, rapid or irregular heartbeat, chest fluttering, shortness of breath, dizziness, confusion, vertigo, or signs of liver problems (such as loss of appetite, upper abdominal pain, fatigue, dark urine, clay-colored stools, or jaundice) or kidney problems (like decreased urination, swelling in the feet/ankles, or unusual tiredness). This is not a complete list of side effects. Discuss any concerns with your healthcare provider, who can advise on management. Suspected adverse reactions can also be reported to the FDA.
