How does Teva-Clonidine work? What will it do for me?

Clonidine belongs to the group of medications called antihypertensives or vascular stabilizers. It is used alone or in combination with thiazide diuretics (e.g., hydrochlorothiazide) to treat high blood pressure. It is usually tried when other types of blood pressure medications are ineffective or cannot be used. This medication works by widening the blood vessels, which increases blood flow and lowers blood pressure.

Clonidine can also be used to relieve menopausal hot flashes when hormone replacement therapy is not needed or not desired. For hot flashes, clonidine works by helping reduce the response of the blood vessels to stimuli that cause them to narrow and widen.

Are there any other precautions or warnings for Teva-Clonidine?

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Depression: This medication can cause symptoms of depression. If you have a history of depression, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. If you experience symptoms of depression such as poor concentration, changes in weight, changes in sleep, or decreased interest in activities, or notice them in a family member who is taking this medication, contact your doctor as soon as possible.

Drowsiness/reduced alertness: Clonidine can cause drowsiness and dizziness and may affect the ability of your eyes to change focus quickly between distance and close up. Avoid driving, operating machinery, or performing other potentially hazardous tasks until you have determined how you are affected by this medication.

Eyes: This medication may affect the eye. People taking clonidine should receive periodic eye examinations. This medication can cause decreased tear production, and contact lenses may become uncomfortable to wear.

Heart or blood vessel disease: Clonidine lowers blood pressure, which can cause worsening of heart conditions that are affected by decreased blood flow. If you have severe heart or blood vessel disease, have recently had a heart attack or stroke, or a slow heart rate, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Kidney function: Kidney disease or decreased kidney function can cause this medication to build up in the body, causing side effects. If you have reduced kidney function, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Lactose: This medication may contain lactose. If you have galactose intolerance, the Lapp lactase deficiency, or glucose-galactose malabsorption, you should not take this medication without talking to your doctor.

Other medical conditions: If you have polyneuropathy or constipation, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Raynaud’s disease: If you have Raynaud’s disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Surgery: If you are having any type of surgery, make sure that the doctors involved in your care are aware that you are taking this medication.

Withdrawal: Don’t stop taking this medication without talking to your doctor. A severe withdrawal reaction may develop within 12 to 48 hours when clonidine is stopped suddenly. This reaction includes a rapid rise in blood pressure and symptoms such as nervousness, agitation, restlessness, pounding heartbeat, nausea, and headache. When stopping clonidine therapy, your doctor will instruct you to reduce the dose gradually over 2 to 4 days to avoid this reaction. A withdrawal reaction is most likely to occur in people who have been receiving large doses of clonidine or who are taking another type of blood pressure medication called a beta-blocker (e.g., atenolol, metoprolol, bisoprolol) at the same time.

Pregnancy: When taken during pregnancy, clonidine crosses the placenta and may cause the developing baby’s heart rate to slow.

This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.

Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are taking clonidine, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding. This medication is not recommended for women who are breast-feeding.
