Azithromycin, while generally safe, can cause side effects. The most common include diarrhea, nausea, and vomiting. These usually resolve without treatment. However, more serious reactions are possible, though rare.
Gastrointestinal Issues: Beyond nausea and vomiting, you might experience abdominal pain or constipation. Severe diarrhea, potentially indicating Clostridium difficile infection, requires immediate medical attention. Drink plenty of fluids to prevent dehydration.
Allergies: Allergic reactions, ranging from mild skin rashes to severe anaphylaxis (a life-threatening reaction), are possible. Stop taking Azithromycin and seek immediate medical help if you experience swelling, difficulty breathing, or hives.
Heart Effects: Prolonged QT interval, a heart rhythm abnormality, is a potential concern, particularly in individuals with pre-existing heart conditions or those taking other medications that prolong the QT interval. Your doctor should be aware of your complete medical history.
Liver Problems: Azithromycin can, in rare instances, cause liver inflammation (hepatitis). Symptoms might include jaundice (yellowing of the skin and eyes), dark urine, or abdominal pain. Report these symptoms to your physician immediately.
Hearing Problems: Though infrequent, temporary or permanent hearing loss has been reported. This is more likely with high doses or in patients with pre-existing hearing difficulties.
Nervous System Effects: Dizziness, vertigo, and headache are possible. Severe neurological reactions are uncommon but may include seizures.
