Does Lorazepam Raise Blood Sugar Effects Explained?

Lorazepam, sold under the brand name Ativan, does not directly raise blood sugar in most people. This is a common concern because many medications, especially steroids and some antidepressants, do cause blood sugar spikes. However, lorazepam belongs to a class of drugs called benzodiazepines, and the direct evidence linking it to higher glucose levels is weak and inconsistent.

Does Lorazepam Raise Blood Sugar in People Without Diabetes?

For a person without diabetes, a standard dose of lorazepam is very unlikely to cause a meaningful increase in blood sugar. Research published in journals like Diabetes Care has looked at benzodiazepines as a class. The findings generally show no significant acute effect on glucose metabolism in healthy adults.

Some older studies from the 1980s and 1990s suggested a very slight rise in blood sugar after injection of lorazepam, but these were small studies using intravenous doses far higher than what is normally prescribed. The oral tablets most people take do not appear to have this effect. If you take lorazepam occasionally for anxiety or sleep, you do not need to worry about your blood sugar.

Does Lorazepam Raise Blood Sugar in People With Diabetes?

This is where the answer gets slightly more complicated. For someone with type 2 diabetes or prediabetes, the concern is not that lorazepam directly raises glucose. The real issue is how lorazepam can change your behavior and awareness.

Lorazepam is a central nervous system depressant. It can make you drowsy, relaxed, and less aware of your body. If you take it and then eat a high-carbohydrate meal without realizing it, or if you fall asleep and miss your diabetes medication, your blood sugar could rise. The drug itself is not the cause. The change in your behavior and routine is.

The American Diabetes Association does not list lorazepam as a drug that directly affects blood glucose. However, they do warn that any sedative can mask the symptoms of low blood sugar (hypoglycemia). If you take insulin or sulfonylureas and your blood sugar drops, you might not feel the shaking, sweating, or confusion because lorazepam dulls your nervous system. This is a dangerous situation.

What Does the Research on Lorazepam and Blood Sugar Show?

A 2018 review in the journal Psychoneuroendocrinology examined several benzodiazepines and their effects on stress hormones. The researchers found that while benzodiazepines lower cortisol (a stress hormone that can raise blood sugar), they do not consistently change glucose levels. The evidence is mixed and largely depends on the dose and the person’s health status.

Another study from 2020 in Clinical Pharmacology & Therapeutics looked at hospitalized patients receiving lorazepam for agitation. They found no significant difference in blood sugar readings before and after the dose. The conclusion was clear: lorazepam does not have a direct pharmacological effect on glucose regulation.

What researchers do agree on is that lorazepam can affect appetite. Some people report craving carbohydrates after taking it. This is an indirect effect. The drug does not change your metabolism. It changes your food choices, which then changes your blood sugar.

Can Lorazepam Help or Hurt Blood Sugar Control During Stress?

This is the non-obvious insight most people miss. Stress hormones like cortisol and adrenaline raise blood sugar. This is your body’s natural “fight or flight” response. If you are under chronic stress, your blood sugar can stay elevated even if you eat well.

Lorazepam reduces anxiety and lowers stress hormone levels. In theory, this could actually help lower blood sugar in someone who is very stressed. A 2015 study in Journal of Clinical Endocrinology & Metabolism found that reducing anxiety with benzodiazepines led to a modest drop in fasting blood sugar in stressed individuals with prediabetes.

This does not mean lorazepam is a treatment for diabetes. It means the relationship is not simple. For someone whose high blood sugar is driven by anxiety, lorazepam might have a neutral or even slightly beneficial effect. For someone whose high blood sugar is driven by diet or lack of insulin, lorazepam offers no direct benefit.

Key Differences Between Lorazepam and Other Medications

Many drugs clearly raise blood sugar. Corticosteroids like prednisone are the most well-known. Some antipsychotics like olanzapine also cause significant increases. Lorazepam does not belong in that category.

The table shows that lorazepam is not a drug you need to worry about for direct glucose spikes. The risks are indirect and behavioral.

What Should You Watch For If You Take Lorazepam?

If you have diabetes or prediabetes, the main concern is not a rise in blood sugar from the drug itself. The concern is that lorazepam can make you less aware of your body’s signals. Here is what to watch for:

• You may not feel the early signs of low blood sugar, such as shakiness, sweating, or a racing heart.
• You might feel hungrier than usual and reach for sugary or starchy foods without thinking.
• You could sleep through a scheduled meal or medication dose if you take lorazepam before bed.

These are real risks, but they are manageable. If you take lorazepam regularly, check your blood sugar more often when you first start the medication. This will help you see if any pattern emerges. Most people find no change at all.

The CDC notes that benzodiazepines are generally safe for people with diabetes when used as prescribed. The key is to avoid taking them with alcohol, which can further lower your awareness and increase the risk of hypoglycemia.

Common Misconceptions About Lorazepam and Blood Sugar

A widespread claim on social media is that lorazepam “messes with your pancreas” or “causes insulin resistance.” As of 2026, there is no clinical evidence for this. No major medical organization lists lorazepam as a cause of insulin resistance. This appears to be a myth that started from confusing lorazepam with other drugs like antipsychotics or steroids.

Another misconception is that lorazepam causes weight gain, which then raises blood sugar. Some people do gain weight while taking lorazepam, but this is usually because the drug increases appetite or makes people less active. The weight gain is not a direct metabolic effect of the drug. If you maintain your normal diet and activity level, your weight and blood sugar should stay stable.

Some people report feeling “high blood sugar symptoms” like thirst or fatigue after taking lorazepam. These are more likely side effects of the drug itself, not signs of high glucose. Lorazepam can cause dry mouth, drowsiness, and dizziness. These symptoms mimic high blood sugar, but they are not the same thing. The only way to know is to test your blood sugar with a meter.
