Can I Give Meftal-P To My Toddler Son 3 Hours After P250 For Persistent High Fever?

Hi My son age 1year 3months. Has high fever nearing 102F for the past one day. My doctor suggested taking P250 and if the fever doesn t reduce after 2 hrs advised to give meftal p syrup and to take alternately both medicine in a gap of 5 hrs. Now it has been 3 hours after taking p250 the fever doesn t reduced. Can I give meftal in 3hrs gap after p250. How long should I wait to give meftal after giving p250?
