Is this topic for you?
Hypoglycemia, or low blood sugar, is most common in people with diabetes. If you have already been diagnosed with diabetes and need more information about low blood sugar, see the topics:
What causes low blood sugar?
Your body uses hormones to keep your blood sugar in a normal range. But a long-term health problem that needs treatment can cause blood sugar to drop too low.
People with diabetes often deal with low blood sugar. It’s not as common in people who don't have diabetes, but it can happen. It could be caused by:
- Medicines such as monoamine oxidase inhibitors (used to treat depression), quinine sulfate (used to treat malaria), and aspirin.
- Drinking too much alcohol.
- Diseases that affect the pancreas, liver, kidneys, adrenal glands, or other organs.
- Metabolic problems that run in families.
- Problems caused by stomach surgery.
What are the symptoms?
The symptoms can be different depending on how low your blood sugar level drops.
- Mild hypoglycemia can make you feel hungry or like you want to vomit. You could also feel jittery or nervous. Your heart may beat fast. You may sweat. Or your skin might turn cold and clammy.
- Moderate hypoglycemia often makes people feel short-tempered, nervous, afraid, or confused. Your vision may blur. You could also feel unsteady or have trouble walking.
- Severe hypoglycemia can cause you to pass out. You could have seizures. It could even cause a coma or death.
If you've had hypoglycemia during the night, you may wake up tired or with a headache. And you may have nightmares. Or you may sweat so much during the night that your pajamas or sheets are damp when you wake up.
How is hypoglycemia diagnosed?
To diagnose hypoglycemia, your doctor will do a physical exam and ask you questions about your health. You will need tests to check your blood sugar levels. Your doctor will also ask you about any medicines you take and whether you have recently lost or gained weight.
If a blood test shows that you have low blood sugar, and if you have symptoms that go away after you eat a snack or drink with sugar in it, you probably have hypoglycemia.
How is it treated?
If you have symptoms of low blood sugar, you need to eat or drink something with sugar in it. For example, you could eat raisins, graham crackers, or candy. You could also drink skim milk, regular (not diet) soda, or fruit juice. You may also take glucose tablets.
It’s a good idea to find out about health problems or situations that can lead to low blood sugar. It’s also important to pay attention to your health and lifestyle. For example, talk to your doctor to see if you can change your diet, change the medicines you take, or change the way you exercise. In some cases, treating the health problem that is causing low blood sugar can prevent future problems.

Indication
Uroxatral® (alfuzosin HCl 10 mg extended-release tablets) is an alpha1-blocker for the treatment of the signs and symptoms of BPH.
Important Safety Information
Do not take UROXATRAL if you have liver problems or if you are taking antifungal drugs like ketoconazole or itraconazole, or HIV drugs like ritonavir.
UROXATRAL can cause a sudden drop in blood pressure, especially when starting treatment. This may lead to fainting, dizziness, and lightheadedness. Do not drive, operate machinery, or do any dangerous activity until you know how UROXATRAL will affect you. This is especially important if you already have a problem with low blood pressure or take medicines to treat high blood pressure. There may be an increased risk of low blood pressure and fainting when taking UROXATRAL in combination with blood pressure medication or nitrates, or erectile dysfunction medication.
If considering cataract surgery (clouding of the eyes), tell your eye surgeon that you are currently taking UROXATRAL or have previously been treated with an alpha-blocker.
Before taking UROXATRAL, tell your doctor if you have kidney problems.
Also, tell your doctor if you or any family member(s) have or take medications for a rare heart condition known as congenital prolongation of the QT interval.
BPH and prostate cancer can cause the same symptoms. However, UROXATRAL is not a treatment for prostate cancer.
The most common side effects with UROXATRAL are dizziness, upper respiratory tract infection, headache, and tiredness.
Please see UROXATRAL full prescribing information.
