Common Use

Clonidine can be taken orally or applied as patches on the skin to treat high blood pressure. It works by altering the concentration of certain chemicals in the blood and stimulating alpha2-adrenoceptors in the brain stem. This reduces the transmission of signals from the brain to other parts of the body, leading to decreased peripheral resistance, renal vascular resistance, heart rate, and blood pressure.

Dosage and Direction

Clonidine is typically taken twice daily, with the dosage adjusted based on the patient's blood pressure response. It should only be used if prescribed by a physician. For patches, apply them to a hairless area on the upper arm or torso, replacing them every 7 days. Rotate the application site with each new patch.

Precautions

Avoid alcohol consumption while using Clonidine. Be cautious when driving or performing tasks that require high concentration.

Contraindications

• Hypersensitivity to Clonidine or any component of the formulation.
• Patients with sick sinus syndrome, bradycardia, or atrioventricular block (degree II and III).
• Use with caution in cases of acute myocardial infarction, Raynaud's syndrome, endogenous depression, kidney failure, and other conditions.

Possible Side Effects

• Allergic reactions like hives, difficulty breathing, or swelling.
• Fast or pounding heartbeats, very slow heart rate, swelling, rapid weight gain.
• Confusion, hallucinations, fever, pale skin, reduced urination.

Seek immediate medical attention if any of these side effects occur.

Drug Interactions

• Clonidine may enhance the sedative effects of barbiturates, narcotic pain relievers, and alcohol.
• Certain antidepressants may reduce its effectiveness.
• Concurrent use with Cyclosporine may increase kidney damage risk.
• Use cautiously with medications that lower heart rate, such as beta-blockers.

Missed Dose

If you miss a dose, take it as soon as you remember. If it's almost time for your next dose, skip the missed dose. Do not take an extra dose to compensate.

Overdose

If you suspect an overdose (symptoms include severe headache, blurred vision, anxiety, confusion, chest pain, fainting, cold feeling, or slow heart rate), seek immediate medical help.

Storage

Store Clonidine tablets and patches at room temperature (15-30°C or 59-86°F) in a light-resistant container, away from moisture.
