Macrolides are bacteriostatic at standard doses but bactericidal at higher concentrations against susceptible organisms. Spectrum includes Streptococcus species (including some penicillin-resistant pneumococci), Mycoplasma pneumoniae, Chlamydia trachomatis and pneumoniae, Legionella, Bordetella, and Helicobacter pylori. Activity against staphylococci is unreliable due to widespread macrolide resistance, and most Enterobacteriaceae are intrinsically resistant.<\/p>\n<p>Clarithromycin has the most consistent <em>Helicobacter pylori<\/em> activity of the macrolide class (where local resistance is &lt; 15%) and is a key component of triple-therapy peptic-ulcer eradication regimens. It is a strong CYP3A4 inhibitor.<\/p>\n<h2 id=\"indications\">Indications &amp; dosing<\/h2>\n<table style=\"width:100%;border-collapse:collapse;margin:14px 0;font-size:14px;\">\n<caption style=\"text-align:left;font-weight:bold;margin-bottom:6px;\">Adult dosing<\/caption>\n<thead>\n<tr style=\"background:#2c7cb0;color:#fff;\">\n<th style=\"padding:8px;border:1px solid #ddd;text-align:left;\">Indication<\/th>\n<th style=\"padding:8px;border:1px solid #ddd;text-align:left;\">Dose<\/th>\n<th style=\"padding:8px;border:1px solid #ddd;text-align:left;\">Duration<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"background:#fff;\">\n<td style=\"padding:8px;border:1px solid #ddd;\">CAP \/ acute bronchitis<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">500 mg twice daily<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">7\u201314 days<\/td>\n<\/tr>\n<tr style=\"background:#f9f9f9;\">\n<td style=\"padding:8px;border:1px solid #ddd;\">Sinusitis \/ otitis<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">500 mg twice daily<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">14 days<\/td>\n<\/tr>\n<tr style=\"background:#fff;\">\n<td style=\"padding:8px;border:1px solid #ddd;\">Helicobacter pylori (triple therapy with PPI + amoxicillin)<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">500 mg twice daily<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">14 days<\/td>\n<\/tr>\n<tr style=\"background:#f9f9f9;\">\n<td style=\"padding:8px;border:1px solid #ddd;\">Mycobacterium avium complex disease<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">500 mg twice daily (combination)<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">Refer specialist<\/td>\n<\/tr>\n<tr style=\"background:#fff;\">\n<td style=\"padding:8px;border:1px solid #ddd;\">Skin \/ soft-tissue infection<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">500 mg twice daily<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">7\u201310 days<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Modified-release clarithromycin 1 g once daily is also available \u2014 same indications, similar efficacy, lower GI side-effect burden.<\/p>\n<div style=\"background:#fff3f3;border-left:4px solid #d9534f;padding:14px 18px;margin:18px 0;border-radius:6px;\"><strong style=\"color:#a94442;\">\u26a0 QT prolongation \u2014 class warning<\/strong><\/p>\n<div style=\"margin-top:6px;font-size:14px;line-height:1.55;\">\n<p style=\"margin:0;\">All macrolides can prolong the QT interval and trigger torsades de pointes \u2014 particularly in patients with congenital long QT, electrolyte disturbance (low K+ \/ Mg2+), bradycardia, concurrent QT-prolonging medications (azoles, fluoroquinolones, citalopram, ondansetron, certain antipsychotics, some antiarrhythmics) or significant cardiac disease.

Azithromycin&#8217;s long intracellular half-life means treatment continues for ~7 days even after a 5-day course ends \u2014 do not assume the course is too short.<\/p>\n<h3>Should I take it with food?<\/h3>\n<p>Clarithromycin can be taken with or without food. The modified-release tablet should be taken with food for best absorption.<\/p>\n<h3>Can I take it if I have heart disease?<\/h3>\n<p>Stable cardiovascular disease is not an absolute contraindication. Patients with congenital long-QT, recent acute coronary events, advanced heart failure, or concurrent QT-prolonging medications should discuss alternatives with their prescriber.<\/p>\n<h3>Why does my doctor avoid clarithromycin with my statin?<\/h3>\n<p>Clarithromycin is a strong CYP3A4 inhibitor and dramatically raises levels of simvastatin and lovastatin \u2014 risk of severe muscle injury (rhabdomyolysis) and acute kidney injury. The statin should be paused for the antibiotic course or switched to a non-CYP3A4 statin (rosuvastatin, pravastatin).<\/p>\n<h3>What if I miss a dose?<\/h3>\n<p>Take it as soon as you remember. If you are within a few hours of the next dose, skip and resume. Do not double up.<\/p>\n<h3>Does Claribid interact with my contraceptive pill?<\/h3>\n<p>Modern evidence does not support clinically important reductions in pill efficacy. Continue your usual schedule. Use additional protection if you experience vomiting or diarrhoea.<\/p>\n<h3>Can I drink alcohol?<\/h3>\n<p>There is no direct interaction. Heavy drinking increases nausea and slows immune recovery \u2014 moderate use is acceptable.<\/p>\n<h3>Will Claribid cover MRSA?<\/h3>\n<p>No \u2014 most MRSA strains are macrolide-resistant via efflux pumps and target modifications. For MRSA, use clindamycin \/ doxycycline \/ TMP-SMX \/ linezolid based on local susceptibility data.<\/p>\n<h3>Why did my doctor give me a single 1 g dose for chlamydia?<\/h3>\n<p>Azithromycin 1 g single oral dose achieves curative tissue levels for >7 days against Chlamydia trachomatis. Confirmed treatment failure rates are low (~5%); test of cure is recommended at 3 months because re-infection is common.<\/p>\n<h3>Can I use this for a viral cold?<\/h3>\n<p>No. Macrolides have no antiviral activity. Using them for the common cold or simple flu provides no benefit, accelerates resistance, and exposes you to QT and GI side effects unnecessarily.<\/p>\n<p><!-- medsbase-related-alts-v1 --><\/p>\n<h2>Other Antibiotics &amp; Anti-Infective Medications<\/h2>\n<ul>\n<li><a href=\"\/azee\/\">Azee (Azithromycin) \u2014 short-course macrolide alternative<\/a><\/li>\n<li><a href=\"\/claribid\/\">Claribid (Clarithromycin) \u2014 H. pylori, atypical pneumonia<\/a><\/li>\n<li><a href=\"\/doxt\/\">Doxt (Doxycycline) \u2014 atypical pneumonia \/ STIs<\/a><\/li>\n<li><a href=\"\/augmentin\/\">Augmentin (Amoxicillin + Clavulanic acid) \u2014 beta-lactam alternative<\/a><\/li>\n<li><a href=\"\/levomac\/\">Levomac (Levofloxacin) \u2014 respiratory fluoroquinolone<\/a><\/li>\n<\/ul>\n<div style=\"background:#fff3f3;border-left:4px solid #d9534f;padding:12px 16px;margin:22px 0 0;border-radius:6px;font-size:13px;color:#555;\"><strong>Medical Disclaimer:<\/strong> The information on this page is provided for educational purposes and does not replace a consultation with a qualified clinician.
