Chronic hypertension, also known as high blood pressure, is a disease that affects the flow of blood from the heart to the blood vessels.
Chronic blood pressure is a serious health problem, and your doctor may prescribe Labetalol to help manage blood flow.
We have created this guide to provide more information about the drug and its uses.
How High Blood Pressure Affects You
Every time the heart beats it creates pressure that pushes blood through vessels, arteries, and other passages. Blood pressure is the result of systolic pressure and diastolic pressure.
Systolic pressure is created by the blood pumping out of the heart, and diastolic pressure is the result of the heart resting before beats. High blood pressure makes your heart work harder to pump blood through the arteries. In turn, blood vessels weaken under the pressure.
The artery wall develops small tears and plaque will start to grow. The plaque blocks the arteries and prevents blood from flowing freely through the passageway.
Artery blockages cause strokes, vision loss, heart failure, kidney failure, and many other diseases.
What is Labetalol?
Labetalol acts as a blockade between the receptors of the adrenergic nervous system and arteries. When someone has high blood pressure, the nervous system releases norepinephrine which constricts arteries and raises blood pressure.
The medication blocks the transmission of norepinephrine to the arteries and decreases blood pressure.
How Often Should You Take Labetalol?
Doctors recommend patients take 100 mg of the drug twice per day. Dosages also depend on the severity of the patient’s blood pressure. Patients with severe pressure take 1.2 to 2.4 grams daily.
The drug can also be taken intravenously through 20 mg doses. Intravenous doses are increased by 20 mg increments over time. The drug can also be delivered through intravenous infusions at 1-2 mg doses.
Intravenous doses are given within minutes of each other.
How Well Does It Interact With Other Drugs?
Doctors advise patients to be careful when taking antidepressants while on Labelatol. Chemical reactions can increase tremors.
Diabetics taking medication for blood sugar should carefully monitor their sugar because the medication can mask signs of hypoglycemia.
This medicine can render asthmatic drugs like albuterol ineffective. Cimetidine works well with the drug so doctors may have to reduce your dosages.
Most patients taking medications are concerned with the longterm side effects. The medication has been linked to liver failure, slower heart rates, sexual dysfunction, abnormal heart rhythm, and allergic reactions to other medications.
Should You Take Labetalol?
The decision to take Labetalol is between you and your doctor. Your doctor understands your health needs and will help you manage health conditions.
Your doctor will also know how the drug reacts with other prescription medications. However, it’s your body, and only you will be able to explain how the medication makes you feel.
It is important to discuss any concerns you have with your doctor. The side effects listed are not necessarily common, and you may not experience any negative effects.
