3. HOW TO TAKE CARVEDILOL TABLETS
Always take Carvedilol Tablets exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
Method of Administration
Carvedilol Tablets should be swallowed whole with a drink of water. Do not crush, chew or suck them.
Dosage
Your doctor will decide on the right starting dose for you and on any increase in the dose depending on your condition and whether you are taking any other medicines. Do not change your dose unless your doctor tells you to do so.
The recommended dose is on the label on the carton which will tell you how many tablets you should take and when.
The usual doses for Carvedilol Tablets are as follows:
Heart Failure
If you have been given Carvedilol Tablets for the treatment of heart failure, it is likely that a hospital specialist will have started your treatment. The usual starting dose is 3.125 mg tablets twice a day (every 12 hours). You should try to take the tablets with food. However, you should still take your tablets even if you do not have much appetite. Your doctor may gradually increase the strength of your tablets until you find a dose that suits you best.
Carvedilol may worsen your symptoms of heart failure. Please tell your doctor if you notice any such change. While taking Carvedilol Tablets, make sure that you continue with any other treatments you may already be taking for heart failure as advised by your doctor.
High Blood Pressure
The usual starting dose is 12.5 mg once a day. Your doctor will gradually increase the strength of tablets you take until you receive the dose that suits you best. The normal dosage is one 25 mg tablet once a day.
Angina
The usual starting dose is 12.5 mg twice a day for the first two days of your treatment. From then on the usual dose is one 25 mg tablet twice a day.
Use in children and adolescents
Carvedilol Tablets are not suitable for children and adolescents under 18 years of age.
If you take more Carvedilol Tablets than you should:
If you (or someone else) swallow a lot of the tablets all together or if you think a child has swallowed any of the tablets, contact your nearest hospital casualty department or your doctor immediately. An overdose can cause low blood pressure (leading to feeling faint, shaky and weak), wheezing, vomiting, fits, very slow heartbeat, heart failure/attack, breathing problems and loss of consciousness.
If you forget to take Carvedilol Tablets
If you forget to take a dose, take one as soon as you remember, unless it is nearly time to take the next one. Do not take a double dose to make up for a forgotten dose.
If you stop taking Carvedilol Tablets
Do not suddenly stop taking your tablets as side effects may occur. If treatment is to be stopped, your doctor will gradually reduce your dose.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
