Hi, You can take Paracetamol, Dolo SOS whenever you have fever, headache or body ache. You should not use paracetamol more than 3 gm per day. There are no much side effects if taken intermittently. Using it for longer time or frequently or in high dosage may cause few side effects. Take care. Hope I have answered your question. Let me know if I can assist you further.
