Azithromycin, while generally safe, can cause side effects. These vary in severity and frequency. Common reactions include diarrhea, nausea, and vomiting. These usually resolve without treatment.
Gastrointestinal Issues
Upset stomach is the most frequently reported side effect. Less common, but still possible, are abdominal pain and changes in bowel habits. Severe diarrhea, potentially indicating Clostridium difficile infection, requires immediate medical attention.
Allergic Reactions
Allergic reactions range from mild skin rashes to severe, life-threatening anaphylaxis. Symptoms of an allergic reaction include hives, swelling, difficulty breathing, and dizziness. Seek immediate medical help if you experience these.
Other Potential Side Effects
Azithromycin can also affect the liver, though this is uncommon. Symptoms of liver problems include jaundice (yellowing of skin and eyes), dark urine, and abdominal pain. Heart rhythm abnormalities, though rare, are a possibility, especially in patients with pre-existing heart conditions. Hearing problems, such as tinnitus (ringing in the ears), are another potential side effect.
Important Considerations
| Nausea, Vomiting, Diarrhea | Common | May resolve spontaneously; consult doctor if severe or persistent. |
| Allergic Reaction (Hives, Swelling, Difficulty Breathing) | Uncommon | Seek immediate medical attention. |
| Liver Problems (Jaundice, Dark Urine) | Rare | Consult doctor immediately. |
| Heart Rhythm Abnormalities | Rare | Seek immediate medical attention. |
Drug Interactions
Azithromycin can interact with other medications. Inform your doctor about all medications, supplements, and herbal remedies you are taking. This includes prescription drugs, over-the-counter medications, and even some supplements.
