Nexiclon XR

Generic name: Clonidine
Drug class: Antiadrenergic agents , Antineoplastic Agents

Usage of Nexiclon XR

Clonidine is used alone or together with other medicines to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk for heart attacks. These problems may be less likely to occur if the blood pressure is controlled.

Clonidine belongs to the class of medicines called antihypertensives. It works in the brain to change some of the nerve impulses. As a result, the blood vessels relax and blood passes through them more easily, which lowers blood pressure. When the blood pressure is lowered, the amount of blood and oxygen going to the heart is increased.

This medicine will not cure your high blood pressure, but it does help control it. Therefore, you must continue to use it as directed if you expect to lower your blood pressure and keep it down. You might have to take high blood pressure medicine for the rest of your life.

Kapvay® extended-release tablets is used alone or together with other medicines to treat attention deficit hyperactivity disorder (ADHD). It works by increasing attention and decreasing restlessness in children and adults who are overactive, cannot concentrate for very long, or are easily distracted and impulsive. This medicine is used as part of a total treatment program that also includes social, educational, and psychological treatment.

This medicine is available only with your doctor's prescription.

    Make sure that you have enough clonidine on hand to last through weekends, holidays, or vacations. You should not miss any doses. You may want to ask your doctor for a second written prescription for clonidine to carry in your wallet or purse. You can have it filled if you run out of medicine when you are away from home.

    Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements. You should avoid over-the-counter [OTC] medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems, since they may tend to increase your blood pressure.

    Clonidine will add to the effects of alcohol and other central nervous system (CNS) depressants. CNS depressants are medicines that slow down the nervous system and may cause drowsiness. Some examples of CNS depressants are antihistamines or medicine for hay fever, allergies, or colds; sedatives, tranquilizers, or sleeping medicine; prescription pain medicine or narcotics; barbiturates or medicine for seizures; muscle relaxants; or anesthetics, including some dental anesthetics. Check with your doctor before taking any of the above while you are using this medicine.

    Clonidine may cause some people to become drowsy or less alert than they are normally. This is more likely to happen when you begin to take it or when you increase the amount of medicine you are taking. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are not alert.

    Before having any kind of surgery (including dental surgery) or emergency treatment, tell the medical doctor or dentist in charge that you are using this medicine.

    This medicine may cause dryness of the eyes. If you wear contact lenses, this may be a problem for you. Talk to your doctor if you wear contact lenses, and discuss how to treat the dryness.

    Dizziness, lightheadedness, or fainting may occur after you take this medicine, especially when you get up suddenly from a lying or sitting position. Getting up slowly may help, but if the problem continues or gets worse, check with your doctor.

    The dizziness, lightheadedness, or fainting is also more likely to occur if you drink alcohol, stand for long periods of time, exercise, or if the weather is hot. While you are taking clonidine, be careful to limit the amount of alcohol you drink. Also, use extra care not to become dehydrated or overheated during exercise or hot weather or if you must stand for a long time.

    If you develop a skin rash, hives, or any allergic reaction to this medicine, stop taking the medicine and check with your doctor as soon as possible.

    Clonidine may cause dryness of the mouth. For temporary relief, use sugarless candy or gum, melt bits of ice in your mouth, or use a saliva substitute. However, if your mouth continues to feel dry for more than 2 weeks, check with your medical doctor or dentist. Continuing dryness of the mouth may increase the chance of dental disease, including tooth decay, gum disease, and fungus infections.
