Take it with food if it causes nausea or vomiting. The dose must be reduced in significant kidney disease, so check with a doctor/pharmacist before using it if you have renal problems.
Seek urgent care for breathing difficulty, chest pain, bluish lips, confusion, dehydration, persistent high fever, or worsening symptoms.
