A cough for 2 days is often due to a viral infection and usually settles on its own. You should not restart Covatil CV 500 Tablet (Cefuroxime and Clavulanic acid) without medical advice, as antibiotics are only needed when there is a clear bacterial infection. AB-Flo Capsule (Acebrophylline) may help in some cases of chest tightness or wheeze, but it should ideally be taken again only after consulting a doctor. Vibact Capsule (Lactobacillus) is a probiotic, but it is generally not necessary in this situation. Simple measures such as warm fluids, steam inhalation, and rest can help, and you should seek medical advice if the cough persists or worsens.
