Taking 2 paracetamol within 24hrs.

The most common side effects following COVID-19 vaccines are fatigue, a fever, headaches, body aches, chills, nausea, diarrhea, and pain at the site of injection, according to the World Health Organization. These may last from a few days to a week and are mostly self limiting. Take medication as prescribed by your doctor and rest. You can keep a clean wet cloth on the affected area to reduce pain. Consult your doctor if redness, tenderness, or swelling of the hand worsens. Drink plenty of fluids to stay hydrated. Avoid doing strenuous activities for at least 3-4 days after getting the vaccine. It is safer to avoid alcohol and smoking for a few days. The vaccine does not fully prevent infection by the COVID-19 virus. However it drastically reduces the chances of severe life threatening consequences and death due to COVID-19.

Take Tablet PARACETAMOL 500mg thrice a day after meals provided you have no prior reaction to the medication.

Be careful not to exceed the safe dosage of PARACETAMOL which is 3 grams/day and 1 gram per dosage. To put it simply; do not exceed 3 tablets of PARACETAMOL per day.
