Your symptoms are likely due to an allergy or a viral infection. Mox 500 mg Capsule contains Amoxycillin (an antibiotic), which treats bacterial infections, not viral ones. You may take an antihistamine such as Cetirizine to relieve sneezing. However, it is best to consult your doctor to determine the exact cause and receive appropriate treatment. Avoid taking antibiotics without a doctor?s advice.
