Hello, I understand your concern. Some of your symptoms may be related to side effects from moxifloxacin or from anxiety/panic triggered after taking the medication. Moxifloxacin can sometimes cause:
- Nausea - Stomach discomfort - Dizziness - Shaky feeling - Anxiety/restlessness - Palpitations
The good sign is that:
- You are breathing - Cough/phlegm is mild and clear - No severe allergic reaction symptoms like rash, facial swelling, or severe breathing difficulty were mentioned
Since your bronchitis symptoms were already improving before starting the antibiotic, it is possible that the medicine may not even be necessary, especially if it was viral bronchitis.
However, because you are feeling faint, shaky, very weak, and unwell after starting it, you should contact the prescribing doctor and discuss whether to stop/change the antibiotic rather than continuing it blindly.
For now:
- Rest - Sip fluids slowly (do not force huge amounts at once) - Eat light food - Avoid caffeine - Stand up slowly to avoid dizziness
⚠️ Seek urgent care immediately if:
- You faint - Chest pain/palpitations become severe - Breathing difficulty develops - Severe vomiting or allergic rash occurs
Final Prescription (Temporary Symptomatic Advice):
- Continue hydration with ORS/electrolyte fluids in small frequent amounts - Tab Paracetamol 500–650 mg SOS after food for body pain/fever - Discuss continuation of Moxifloxacin with your doctor before next dose
Advice: Many acute bronchitis cases are viral and self-limiting. Because symptoms started soon after the medicine, side effects or anxiety reaction should be considered.
Feel free to reach out again.

Hello
Moxifloxacin belongs to a group of antibiotics that can sometimes cause strong side effects even after the first dose. The timing of your symptoms — starting the next day after taking it — makes the medication a possible cause, especially since you describe extreme thirst, dry throat, shakiness, nausea, stomach pain, weakness, anxiety/panic feelings, poor sleep, and feeling faint.
Some of these effects can happen because the medicine may affect the nervous system, stomach, hydration level, blood sugar, or heart rhythm in sensitive people. Feeling “heavy legs,” shaky, and faint can also happen if your blood pressure dropped temporarily, if you became dehydrated from not eating well, or from anxiety triggered by the medication. Drinking a lot of water without electrolytes can sometimes still leave you feeling weak or unwell.
Because your bronchitis symptoms had almost resolved before starting the antibiotic, it is reasonable to speak with the doctor promptly about whether this medication is still necessary or whether a different treatment would be safer. Do not take another dose until you have spoken to a healthcare professional, especially if the symptoms are continuing.
For now:
* Rest and avoid exertion. * Sip fluids slowly; an oral rehydration drink or electrolyte drink may help more than plain water alone. * Eat light foods if you can tolerate them. * Avoid caffeine and alcohol. * Monitor for worsening symptoms.
Get urgent medical care immediately if you develop chest pain, palpitations, severe shortness of breath, swelling, severe diarrhea, confusion, severe weakness, tendon pain, fainting, or a spreading rash.
Take care
