Biaxin Information

Biaxin (clarithromycin) is a prescription macrolide antibiotic used to treat a range of bacterial infections, including respiratory tract infections, sinusitis, bronchitis, pneumonia, skin and soft tissue infections, and certain ear infections. It works by inhibiting bacterial protein synthesis, stopping the growth of susceptible bacteria and helping your immune system clear the infection. Available as tablets, extended‑release tablets, and oral suspension, Biaxin offers flexible dosing options for different ages and clinical needs. Use only for confirmed or strongly suspected bacterial infections to support antibiotic stewardship.

Biaxin (clarithromycin) binds to the 50S subunit of bacterial ribosomes, blocking protein synthesis that bacteria need to grow and replicate. This targeted action slows and stops bacterial proliferation, allowing your body’s defenses to eliminate the infection more effectively. As a macrolide antibiotic, it provides broad coverage against many common respiratory and skin pathogens. Its tissue penetration contributes to steady therapeutic levels where infections commonly occur.

Clinicians prescribe Biaxin for community‑acquired pneumonia, acute bacterial sinusitis, acute exacerbations of chronic bronchitis, pharyngitis/tonsillitis, otitis media, and uncomplicated skin and soft tissue infections when caused by susceptible organisms. It is also used in combination regimens to help eradicate Helicobacter pylori in selected patients with peptic ulcer disease. Suitability depends on local resistance patterns, your medical history, and specific diagnostic findings. Your healthcare provider will determine the best antibiotic based on your situation.

Take Biaxin exactly as prescribed and complete the full course, even if you feel better early, to reduce relapse and resistance. You may take standard tablets with or without food, while extended‑release tablets are typically taken with food; always follow your label directions. Shake oral suspension well and measure doses with a proper device for accuracy. If symptoms don’t improve within a few days or worsen, contact your healthcare provider.

Common side effects include nausea, diarrhea, abdominal discomfort, headache, and changes in taste, which are usually mild and temporary. Taking doses with a light meal and staying hydrated may reduce stomach upset. If you develop a persistent or severe rash, significant diarrhea, yellowing of the skin or eyes, dark urine, or unusual fatigue, seek medical advice promptly. Report any side effects that are troublesome or don’t go away.

Biaxin can, in rare cases, cause liver problems, severe intestinal conditions, and heart rhythm changes (including QT prolongation), especially in those with existing risk factors. Seek urgent help for chest pain, palpitations, fainting, severe dizziness, or symptoms of a serious allergic reaction such as swelling or trouble breathing. People with myasthenia gravis may experience worsening symptoms and should discuss risks with their clinician. Always use Biaxin under medical supervision and disclose your full health history.

Yes—clarithromycin can interact with many drugs, including certain statins, anticoagulants (e.g., warfarin), antiarrhythmics, colchicine, some antidiabetics, and medicines metabolized by CYP3A4. Combining it with other QT‑prolonging drugs may increase the risk of heart rhythm issues. Some antacids and supplements can affect absorption or side effects; provide a complete list of everything you take to your clinician and pharmacist. Never start, stop, or change doses without professional guidance.

Use during pregnancy or breastfeeding requires individualized medical advice, as potential benefits must be weighed against possible risks. Your clinician may recommend alternative antibiotics that have more established safety profiles in these situations. If Biaxin is deemed necessary, careful monitoring and the lowest effective duration are typically advised. Always discuss pregnancy plans or nursing status before starting treatment.

Alcohol can worsen side effects like nausea, dizziness, and dehydration, so it’s best to limit or avoid it during treatment. Caffeine is not directly contraindicated, but both coffee and energy drinks can aggravate stomach upset in sensitive individuals; moderation is wise. Maintain good hydration and avoid grapefruit products unless your clinician confirms they’re safe for you. If you notice increased side effects, adjust intake and consult your provider.

Store tablets at room temperature away from moisture and heat, and keep oral suspension as directed on the label; discard any unused suspension after the recommended period. If you miss a dose, take it as soon as you remember unless it’s close to the next dose—do not double up. Keep all antibiotics out of reach of children and use only the medication prescribed for you. Proper storage and adherence help ensure Biaxin (clarithromycin) works effectively and safely.
