My mom has a diabetes problem, help reduce fever?

Patient: My mom is 83 with diabetes, and is on medication. The medication is Gabapentin 100mg + 300mg, 4 times a day. She is on Janumet 100mg/50mg, and takes 2 tablets of it a day. She also takes Mylan-Nifedipine E 60mg, which she takes once a day. She also takes SDZ-Valsartan 80mg, once a day. She takes Gen-Metoprolol (TY 50mg) twice a day. She has a very high fever ever since last night (July 19th, 2015). Can you please help me what can I give her for the temperature to drop down? So that it doesn’t interfere with her medication?
