In this article, we will explore the common and rare side effects associated with Azithromycin, providing you with the knowledge you need to make informed decisions about your health.

What is Azithromycin?

Azithromycin belongs to a class of antibiotics called macrolides, which are used to combat various bacterial infections. It is commonly prescribed for respiratory tract infections, skin infections, and sexually transmitted diseases. Azithromycin works by inhibiting the growth of bacteria, allowing the body’s immune system to fight off the infection more effectively.

Common Side Effects

While many individuals tolerate Azithromycin well, some may experience certain side effects. These side effects are generally mild and temporary, subsiding as the body adjusts to the medication. The most common side effects include:

Gastrointestinal Issues

  1. Nausea and Vomiting: Some individuals may feel nauseous or experience vomiting shortly after taking Azithromycin. This can usually be minimized by taking the medication with food.
  2. Diarrhea: Azithromycin can occasionally cause diarrhea, which may be accompanied by abdominal cramping. Staying hydrated and consuming a balanced diet can help alleviate this symptom.

Allergic Reactions

Allergic reactions to Azithromycin are rare but can occur. If you notice any of the following symptoms, seek immediate medical attention:

  1. Rash and Itching: Skin rashes and itching may develop as an allergic reaction to the medication. Discontinue use and consult a healthcare professional if these symptoms arise.
  2. Swelling and Difficulty Breathing: In severe cases, Azithromycin can cause swelling of the face, lips, tongue, or throat, leading to breathing difficulties. This is a medical emergency, and urgent medical attention is necessary.

Azithromycin can affect liver function in some individuals, although this is uncommon. Regular monitoring of liver enzymes may be required for individuals with pre-existing liver conditions. If you experience any of the following symptoms, consult your healthcare provider:

Some individuals may experience mild neurological symptoms while taking Azithromycin. These symptoms typically resolve on their own and do not require medical intervention. However, if they persist or worsen, consult your healthcare provider:
