Taking propranolol slows the heartbeat and makes it easier to pump blood into the body. Generally, this drug is prescribed to treat various heart disorders and high blood pressure, but it can also be used to relieve symptoms of psychological anxiety such as tremors and sweating.

After taking the first dose of the drug, the patient may suffer from dizziness, therefore, doctors advise that it be taken before bed, and if it does not cause dizziness, it can be taken in the morning.

In addition to dizziness, the drug can cause a feeling of tiredness and coldness in the feet and hands, and it may also cause difficulty sleeping and bad dreams, but all of these effects are mild and last for a short period.

Who is propranolol prescribed for?

This medicine is prescribed for both children and adults, but it is not used to treat high blood pressure in children under 12 years of age.

This medicine is not suitable for all patients, and in order to be sure that it is suitable for you, you must discuss this with the doctor. It is necessary to inform the doctor if you suffer from:

How and when to take propranolol?

There are two types of propranolol:

  • The rapid type: which dissolves in the body quickly and has a rapid effect, this type may need to be taken several times a day.
  • Slow type: It dissolves slowly in the body and therefore its effect is not as fast. In general, most patients only need one dose per day.

If it was prescribed to you as one dose per day, the doctor may ask you to take it before bed, so that you do not feel dizzy, and if you do not feel dizzy after taking the first dose, you can take it in the morning.

Important note: You should not stop taking the medicine even if you feel better, only your doctor should decide to stop taking the medicine or reduce the dose after evaluating your condition.

Dose

How much medicine to take depends on your condition. This will be decided by the doctor.

For adult patients and children 12 years of age or older, the dosage is as follows:

  • For the treatment of high blood pressure: 80 mg twice a day. However, if the patient does not feel any improvement and the high blood pressure persists, the dose may be increased to 160 mg twice a day as a maximum.
  • For migraine or angina (chest pain): 40 mg 2 – 3 times a day. The doctor may also increase this dose to 240 mg.
  • For the treatment of arrhythmias: 10 – 40 mg 3 – 4 times a day.
  • For anxiety treatment: 40 mg once a day, 40 mg 3 times a day can also be taken.
  • Hyperthyroidism (thyrotoxicosis): 10 – 40 mg 3 – 4 times a day.

For elderly patients or those with kidney or liver disease. Doses may be lower.

If the doctor finds it necessary to give propranolol to a child under 12 years old, the doctor will measure the child’s weight and determine the appropriate dose for him.

How to take medication

Propranolol can be taken with or without meals. But you should take it the same way every day.

The tablets are taken with water, and if it feels difficult to swallow all at once, divide the tablet in half.

For syrup, the medicine usually comes from a spoon that helps determine the amount of dose, if you do not find the spoon, consult a doctor or pharmacist, we do not advise you to use a tablespoon.

If you forget to take the medicine

If you forget to take the medicine, you should take it as soon as you remember, but if it is almost time for the next dose, then there is no need to take the forgotten dose. Wait a while and then take the next dose as scheduled.

Under no circumstances should two doses be taken at the same time, do not take an extra dose to make up for the forgotten dose.

If you always forget to take your medication, we recommend that you use the alarm on your phone to remember dosing times on time.

If you take a large dose

Taking more propranolol will cause the heart rate to slow down, make breathing more difficult, and may lead to shivering and dizziness.

In the event that a large dose was taken and you felt abnormal symptoms, call an ambulance immediately or go to the nearest hospital, in this case, you should not drive the car because you may feel dizzy and lose control, which causes a danger to your life and the lives of others, ask another person to drive the car Or go to the hospital by taxi.

When you go to the hospital, take the medicine package with you so that the doctors know the condition they are treating.
