Biaxin is the brand name for the antibiotic medication Clarithromycin. It belongs to the macrolide class of antibiotics and is commonly prescribed to treat various bacterial infections.

Clarithromycin works by inhibiting the growth and spread of bacteria in the body. It does this by interfering with the protein synthesis process that is essential for bacteria to survive and multiply.

Antibiotic is often used to treat respiratory tract infections, such as bronchitis and pneumonia. It can also be prescribed for certain types of skin and soft tissue infections, as well as certain bacterial infections of the sinuses, throat, and ears. Additionally, Biaxin may be part of the treatment regimen for certain gastrointestinal infections caused by Helicobacter pylori bacteria.

Biaxin is available in different formulations, including tablets, extended-release tablets, and oral suspensions.

Biaxin is a macrolide antibiotic


Typically, the recommended dosage for Biaxin in adults for most infections is:

  • For respiratory tract infections: 250 to 500 mg taken twice daily (every 12 hours) for 7 to 14 days.
  • For skin and skin structure infections: 250 to 500 mg taken twice daily for 7 to 14 days.
  • For Helicobacter pylori infection: Biaxin is used in combination with other medications, and the dosage may vary. It is best to follow your doctor's instructions in this case.

For children, the dosage of Biaxin is usually based on their weight. The pediatric dosage may range from 7.5 mg/kg to 15 mg/kg of body weight per day, divided into two doses.

It is essential to complete the full course of Biaxin as prescribed, even if you start feeling better before finishing the medication. This helps ensure that the infection is completely treated and reduces the risk of antibiotic resistance.

How to Take

Here are some general guidelines:

  1. Read the instructions: Carefully read the information leaflet that comes with the medication. It provides important details about the medication, including any specific instructions or precautions.
  2. Timing: Biaxin is usually taken with or without food. However, some forms of this drug, such as extended-release tablets, should be taken with food to enhance absorption and reduce the risk of stomach upset.
  3. Swallowing: Swallow the tablet or capsule whole with a full glass of water. Do not crush, chew, or break the tablet or capsule unless specifically instructed by your doctor.
  4. Duration: Take Biaxin for the full prescribed duration, even if you start feeling better before completing the medication. Stopping the medication early may allow the infection to return or worsen.

Biaxin can potentially interact with other medications, supplements, or substances, which may affect its effectiveness or increase the risk of side effects. Here are some common interactions:

Medications that may increase the risk of side effects or affect the metabolism of Biaxin:

  • Statins (cholesterol-lowering medications): Such as atorvastatin, simvastatin, lovastatin. Taking Biaxin with these medications can increase the risk of muscle-related side effects.
  • Warfarin: Biaxin may enhance the effects of warfarin, an anticoagulant, and increase the risk of bleeding. Close monitoring of blood clotting times is necessary if you take both medications.
  • Digoxin: Clarithromycin can increase the levels of digoxin in the blood, leading to potential toxicity. Regular monitoring of digoxin levels is recommended if you take both medications.

Medications that may be affected by Biaxin and require dosage adjustments:

  • Carbamazepine: Biaxin can increase the levels of carbamazepine in the blood, potentially leading to side effects.
  • Theophylline: Medicine may increase the levels of theophylline, a medication used for respiratory conditions, and lead to side effects. Monitoring theophylline levels and adjusting the dosage is important in such cases.
  • Colchicine: Concomitant use of Biaxin and colchicine can increase the risk of colchicine toxicity. Dose reduction or avoidance of colchicine may be necessary.

Medications that may reduce the effectiveness of Biaxin:

  • Rifampin: Taking Biaxin with rifampin, an antibiotic used to treat tuberculosis and other infections, may reduce the effectiveness of Biaxin. Alternative antibiotics may be considered in such situations.

These are not the only possible interactions with Biaxin, and there may be other medications or substances that can interact with it.


Here are some important warnings associated with Biaxin:

  1. Allergic reactions: Some individuals may be allergic to Biaxin or other macrolide antibiotics. If you experience signs of an allergic reaction, such as rash, itching, swelling, dizziness, or difficulty breathing, seek immediate medical attention.
  2. Liver problems: Clarithromycin can cause liver problems, including hepatitis or liver failure. Inform your doctor if you have a history of liver disease or if you experience symptoms such as jaundice (yellowing of the skin or eyes), dark urine, abdominal pain, or persistent nausea.
  3. QT prolongation and arrhythmias: Biaxin may cause an abnormal heart rhythm condition called QT prolongation, which can be serious and potentially life-threatening.
  4. Myasthenia gravis: Medicine may worsen symptoms of myasthenia gravis, a neuromuscular disorder characterized by muscle weakness and fatigue. Inform your doctor if you have this condition or if you experience increased muscle weakness while taking Biaxin.
  5. Clostridium difficile-associated diarrhea: Antibiotic use can lead to the overgrowth of a bacteria called Clostridium difficile, resulting in severe diarrhea.
  6. Pregnancy and breastfeeding: Biaxin should be used during pregnancy only if clearly needed. It is excreted in breast milk, so caution should be exercised if breastfeeding.
  7. Resistance and secondary infections: Overuse or misuse of antibiotics, including Clarithromycin, can lead to antibiotic resistance and the development of secondary infections. Take Biaxin as prescribed and only for the recommended duration.
  8. Gastrointestinal effects: Clarithromycin may cause gastrointestinal side effects such as nausea, vomiting, abdominal pain, and diarrhea. Taking it with food or dividing the doses may help reduce these effects.
  9. Neurological effects: Drug has been associated with neurological effects, including confusion, hallucinations, and disorientation.

Biaxin and Alcohol

It is generally recommended to avoid consuming alcohol while taking Biaxin. Alcohol can interact with the medication and increase the risk of certain side effects. Here are a few reasons why it is advisable to avoid alcohol while on Biaxin:

  1. Increased risk of gastrointestinal side effects: Both Biaxin and alcohol can individually cause gastrointestinal side effects such as nausea, vomiting, stomach upset, and abdominal pain. Consuming alcohol while taking Biaxin may exacerbate these symptoms and make you more prone to experiencing gastrointestinal discomfort.
  2. Potential for liver toxicity: Clarithromycin is metabolized in the liver, and alcohol consumption can also put stress on the liver. Concurrent use of Biaxin and alcohol may increase the risk of liver damage or impair the liver's ability to process the medication effectively.
  3. Negative impact on immune system function: Alcohol consumption can weaken the immune system, making it less effective in fighting infections. Taking tablets for the treatment of an infection requires optimal immune function to aid in the recovery process. Alcohol can interfere with this process and potentially reduce the effectiveness of the medication.
  4. Increased risk of side effects: Biaxin can cause dizziness, drowsiness, and blurred vision as side effects. Alcohol has similar effects on the central nervous system. Combining the two substances may intensify these side effects, leading to increased drowsiness, impaired coordination, and reduced alertness.
  5. Overall treatment effectiveness: Alcohol can interfere with the absorption and metabolism of medications, potentially affecting the efficacy of Biaxin. To ensure the best possible treatment outcomes, it is recommended to avoid alcohol consumption while taking Biaxin.

It is important to note that the specific interactions between Biaxin and alcohol may vary depending on individual factors and the dosage of both substances.
