1. What Catapresan is and what it is used for

Catapresan contains an active substance called clonidine, which belongs to a group of medicines known as imidazoline receptor agonists (medicines that lower blood pressure).

Catapresan is used for the treatment of high blood pressure in all its forms.

2. What you need to know before taking Catapresan

Do not take Catapresan:

  • if you are allergic to clonidine hydrochloride or to any of the other ingredients of this medicine (listed in section 6)
  • if you have severe bradycardia (slow heart rate).

Warnings and precautions

Talk to your doctor or pharmacist before taking Catapresan:

  • if you have mild or moderate bradycardia (slow heart rate)
  • if you have cerebral or peripheral circulatory disorders
  • if you suffer from depression
  • if you have polyneuropathy (a type of nervous system disorder)
  • if you suffer from constipation
  • if you have renal insufficiency (see section 3)
  • if you are considering stopping treatment (see section 3)
  • if your treatment includes a beta-blocker (a medicine used to treat high blood pressure and heart problems). In this case, you must follow your doctor's instructions when discontinuing treatment
  • if you have heart problems such as heart failure or severe coronary disease. In such cases, as with other medicines used to treat high blood pressure, careful medical monitoring is required
  • if you wear contact lenses, as this medicine may reduce tear production.

Clonidine is not expected to have any therapeutic effect if you have hypertension caused by a pheochromocytoma (a condition that may lead to increased blood pressure).

Children and adolescents

Do not give Catapresan to children and adolescents. Specifically, when used outside authorized indications in combination with methylphenidate (a medicine used to treat attention deficit hyperactivity disorder (ADHD) in children), serious adverse reactions, including death, have been observed.

Taking Catapresan with other medicines

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.

In particular, inform your doctor if you are taking any of the following types of medicines:

  • Other medicines intended to lower blood pressure: the blood pressure-lowering effect of this medicine may be enhanced.

  • Non-steroidal anti-inflammatory drugs (NSAIDs): the effect of this medicine may be reduced.

  • Medicines with alpha-2 blocking properties such as phentolamine or tolazoline: the effect of this medicine may be counteracted.

  • Beta-blockers and digitalis derivatives (medicines used to treat high blood pressure and heart problems) may cause or worsen bradycardia (slow heart rate) when administered together with clonidine. In addition, beta-blockers may cause or worsen peripheral circulatory disturbances.

  • Tricyclic antidepressants (used to treat depression) or neuroleptics (used to treat certain mental illnesses): concomitant administration with this medicine may cause or worsen orthostatic regulation disorders (changes in blood pressure upon changing position), and may also reduce or abolish the hypotensive effect of clonidine.

Clonidine may enhance the effects of central nervous system depressants (also known as sedatives or tranquilizers).

Taking Catapresan with food, drinks and alcohol

Clonidine may enhance the effects of alcohol.

Pregnancy, breast-feeding and fertility

If you are pregnant, breast-feeding, think you may be pregnant, or are planning to become pregnant, consult your doctor or pharmacist before using this medicine.

During pregnancy, clonidine should only be used in cases of extreme necessity, with careful monitoring of both mother and child, since clonidine may reduce the fetal heart rate and cause a transient increase in blood pressure in the newborn after delivery.

There is insufficient data on the long-term effects of prenatal exposure.

During breast-feeding, the use of this medicine is not recommended, as sufficient information is not available.

There are no data on the effect of clonidine on fertility.

Driving and using machines

Catapresan may cause sedation, drowsiness, and accommodation disorders (difficulty of the eye to focus). Therefore, caution is advised when driving or operating machinery.

Catapresan contains lactose.

If your doctor has informed you that you have an intolerance to certain sugars, consult him before taking this medicine.

3. How to take Catapresan

Follow exactly the instructions for use of this medicine as given by your doctor or pharmacist. If in doubt, consult your doctor or pharmacist again.

The treatment of hypertension requires regular medical supervision.

The dose of Catapresan will be determined according to each patient's individual blood pressure response.

Most mild to moderate hypertension cases respond to an average dose of 2 tablets daily, one in the morning and one at night before going to bed. It is recommended to start treatment with 1 tablet at night, and after 10–15 days, proceed with one tablet in the morning and one at night.

If necessary, the dose may be increased after a period of 2–4 weeks to achieve the desired response, preferably by increasing the nighttime dose.

In cases of severe hypertension, it may be necessary to further increase each dose up to 2 tablets (0.3 mg); this dose may be repeated up to four times daily (8 tablets = 1.2 mg).

The tablets should be taken with a little liquid.

The tablet may be divided into equal doses.

Renal impairment

The dose should be adjusted according to:

  • the individual antihypertensive response, which may vary significantly in patients with renal impairment
  • the degree of renal deterioration

In both cases, careful monitoring is required.

Since only a minimal amount of clonidine is removed during routine hemodialysis, it is not necessary to administer a supplemental dose of clonidine after dialysis.

If you take more Catapresan than you should

Symptoms of overdose may include reduced pupil size, lethargy, slowed heart rate, hypotension, decreased body temperature, drowsiness (including coma), and reduced respiratory rate.

In addition, an increase in blood pressure may also occur.

If you take more Catapresan than you should, contact your doctor, pharmacist, or call the Toxicology Information Service immediately at 91 562 04 20.

If you forget to take Catapresan

Do not take a double dose to make up for forgotten doses.

If you stop taking Catapresan

Do not stop treatment abruptly without first consulting your doctor, as after prolonged treatment with high doses, symptoms such as restlessness, palpitations, rapid rise in blood pressure, nervousness, tremor, headache, or nausea may occur.

If you are taking this medicine in combination with a beta-blocker, follow your doctor's instructions for discontinuing treatment.

If you have any further questions about the use of this medicine, ask your doctor or pharmacist.
