<s>[INST] Hi, I gave Pentaxim to my 18 months old son. Once he came home, he started reacting differently. He is getting anger soon for everything, he will get angry and go to any corner of the room and stare at one place for sometime. He has around 100 F fever also with diarrhea and not drinking water. Please advise how to deal with this. Thanks Indhu [/INST] Hi, I had gone through your question and understand your concerns.Fever, redness, tiredness, fussiness , vomiting and slight irritability can occur after DPT vaccine , but loose motions does not seems to be related to this . Usually symptoms subside in 1-3 days , but if persist consult health care provider , or if any signs of urgent concern like  very high fever, behaviour changes or any sign of severe allergic reaction like swelling over body, hives  ,any difficulty noticed in respiration  ,dizziness, and weakness do consult urgently to your health care provider. For pain and fever you can use paracetamol .Hope this answers your question.
