Can Simvastatin and Levothyroxine affect blood sugar levels?

I am taking one tablet a day for simvastatin 40mg and levothyroxine 75 mcg 1 and 1/2 on Monda and Friday and one tablet on the other days. Just got my blood work back and now my sugar level is high. Can taking these cause a increase in my hemoglobin?

For the past 3 weeks my husband has experienced a dull pain, lasting 7 seconds a couple of times a day just above his heart. After visiting his primary care doc, emergency room for tests--EKG, chest x-ray, blood work, which were all clear, he has been advised to see a cardiologist, which we will do. Wondering if could be a side affect of Levothyroxine, Simvastatin or Slo Niacin which he has been taking for years.

Hello, I am a female aged 68 and have taken levothyroxine since 1997. I now also take Losartan, Clopidogrel and Simvastatin the latter two since a TIA in Feb 2016. I take the first 3 tablets first thing on empty stomach with water and then have breakfast. A friend who has just started on Levothyroxine has been told to take 30 mins before eating but I have never had this advice, and am a little concerned. A recent full blood test shows everything as showing normal.

70 year old female prescribed amlodipine 10 mg added to current medications for high blood pressure (atenolol 100 mg, lisinopril/hydrochlorthiazide 20-12.5mg) following treatment at local clinic for poison ivy treatment with steroids. The clinic recommended a follow up visit to the family doctor for 192/95 reading at the clinic prior to the steroid treatment). The family doctor prescribed the above amlodipine to be added because the blood pressure reading was similar to the clinic reading. Other medications are as follows: levothyroxine 75 mcg, simvastatin 40 mg, and prevent 10 mg, over the counter . The two questions I have are:1. Should the simvastatin dose be less than 20 mg while on amlodipine?2. Does the Prevagen (calcium binding protein) affect the Amlodipine (calcium channel blocker) in any way?
