Medications either prescription or OTC may be an issue for individuals who wish to control their glucose levels. Check out the list of drugs that raise blood sugar here:

Steroids

People take corticosteroids to treat health problems like rheumatoid arthritis and asthma. These drugs might be successful in managing these issues. Also, they may cause mess over the glucose levels. On reducing the steroid doses or stopping the medicine, the blood glucose levels revert to their previous readings. These steroids can be prednisone or prednisolone.

These medicines are helpful for treating medical problems relating to inflammation. These medical conditions include asthma, arthritis, hypersensitivities, and joint injuries. Corticosteroids present in skin creams or inhalers do not have an effect on sugar levels. As they fail to enter the bloodstream in sufficient amounts. However, corticosteroids via injection or oral may considerably increase blood sugar levels.

Summary

Corticosteroids bring about high blood glucose in diabetic patients. These drugs increase the liver’s resistance to insulin. It results in insulin resistance in diabetics while they’re consuming the medicine.

Antihypertensive Drugs

Diuretics i.e., medicines that manage a person’s blood pressure. They work by removing fluid from the body. This causes more often urination and might also elevate the blood glucose levels. Common medicines involve hydrochlorothiazide and furosemide.

Antipsychotics

Patients experiencing mental problems like schizophrenia depend upon antipsychotic medications. They help to manage their signs. These medications might be lifesaving. Also, they elevate the levels of blood glucose particularly,

  • aripiprazole
  • quetiapine fumarate
  • olanzapine
  • risperidone
  • ziprasidone
  • clozapine

If a person is taking any of these especially, olanzapine, he or she must regularly check their glucose levels before beginning the medication. These medicines are used for months or years, hence it may be a problem to have knowledge of.

Beta-blockers treat heart issues. They also have an impact on blood glucose levels. Beta-blockers medicines may include:

  • propranolol
  • atenolol
  • bisoprolol
  • acebutolol
  • metoprolol

This huge category of heart medications reduces blood pressure. They also treat a range of other medical conditions, such as abnormal heartbeat and anxiety. Also, these medications elevate a person’s glucose levels. Few beta-blockers exert less effect on the sugar levels than others. However, these medicines are at times more costly and might not be under insurance. In addition, beta-blockers might mask tachycardia relating to low blood glucose.

Summary

Blood pressure drugs remove sodium and potassium from the body. Potassium is known to absorb glucose into fat and muscle tissue. Thus, in the absence of potassium levels, blood glucose levels might rise.

Birth Control Pills

Oral contraceptives may increase glucose levels in a diabetic person. Even if the increase isn’t a big one, professionals note that one must be aware of this known side effect before beginning this medicine. Heart attack and stroke are chief killers among diabetics and are not effective medicines for statins.

And, for prediabetics, using a statin-associated with a higher risk of developing full-scale diabetes. The use of statins relates to a 30% greater risk of diabetes.

Summary

Statins lower down insulin secretion in type 2 diabetics. And, causes overall insulin resistance in type 1 diabetic patients as well. Both of these would elevate the levels of blood sugar.

Antibiotics to Kill Infections like UTIs and Pneumonia

Antibiotics (fluoroquinolones) are helpful in the treatment of pneumonia and urinary tract infections (UTIs). They result in very low and high blood glucose levels. Moreover, pentamidine, an antimicrobial medication used in the treatment of a type of pneumonia, might also raise the levels of blood glucose.

Can amlodipine elevate blood glucose?

Calcium channels releases insulin from the beta cells of pancreas. Hence, calcium channel blockers (amlodipine) may bring about high blood sugar when used in diabetics.

Do antibiotics elevate the levels of blood glucose?
