Nausea, stomach discomfort, dizziness, and a feeling of weakness can occur as side effects of azithromycin (HHAZI 250) in some people. Mild symptoms may improve after taking the medicine with food and drinking enough water, but continuous or severe nausea and dizziness should not be ignored, especially if they are making you feel unwell or affecting daily activities. Since you were prescribed the medicine for eyelid irritation, it is important to contact your dermatologist again and inform them about these side effects. Your doctor may decide to reduce the dose, change the medicine, or check if the symptoms are due to another cause. Do not stop or continue the antibiotic for a long period on your own without medical advice. Also, use the eye ointment exactly as prescribed and avoid rubbing or touching the eyes frequently. If you develop severe vomiting, rash, breathing difficulty, fainting, palpitations, swelling, or worsening eye redness and pain, seek medical care immediately. Until you speak with your doctor, avoid driving or activities that require full alertness if the dizziness is significant.
