Betaxolol (Oral)

Betaxolol is a beta-blocker used to lower the blood pressure in patients to reduce their risk of heart attacks, heart failure, strokes, and kidney failure.


Betaxolol is part of the medicine group of beta-blocking agents. These beta-adrenergic blockers are used to lower the blood pressure in patients.

Beta-adrenergic blockers work by stopping natural nerve responses in the body. This blocks natural functions of the heart and arteries and forces the blood vessels to relax in certain parts of the body. This relaxing of blood vessels results in a lowering of the blood pressure.

Untreated high blood pressure, which is also known as hypertension, will stop the heart and arteries from working properly. When the blood pressure is too high, the blood is unable to absorb enough oxygen from the lungs and is thus unable to transport enough oxygen to the heart. If it continues untreated, hypertension can result in blood vessel disease, heart failure, strokes, kidney failure and heart attacks. If the condition is controlled with the use of Betaxolol then these problems are less likely to occur in the patient.

This medication is only available with a doctor's prescription.

This medication is not a cure for high blood pressure. Instead, it interrupts natural functions in the body to prevent the blood vessels from tightening. If the treatment is stopped then the medication will cease to be effective.

This medication is usually prescribed along with advice on how to naturally lower the blood pressure. This can involve taking steps to eat more healthily, reduce salt intake, lose weight and exercise. Only by lowering the blood pressure naturally can patients hope to remove the risks of hypertension and cease use of Betaxolol.

This medication should be prescribed along with advice on how you can lower your blood pressure naturally. This treatment is not a cure for high blood pressure. Instead, it is a temporary treatment that lowers your blood pressure by blocking natural processes within the body. Your doctor may advise you on how to control your weight, lose weight, lower your salt intake and undertake exercises to lose weight. Discuss ways in which you can lower your blood pressure naturally with your doctor.

Patients with high blood pressure will often feel fit and healthy and be unaware of the strain that is being placed on the heart and arteries. Even when this is the case it is vital that you continue to take Betaxolol as instructed. The medication only temporarily lowers your blood pressure and ceasing use will lead to a rapid increase in blood pressure. This rapid increase alone can trigger significant problems in the body and if your blood pressure stays high then the risk will increase too. Risks to life from high blood pressure include strokes, heart attacks, heart failure, kidney failure and blood vessel disease. You should never cease taking the prescribed dose of Betaxolol without first discussing this with your doctor.

The dose of this medication will vary depending on the patient, their weight, their medical conditions, the strength of the medication and their blood pressure. The following dosages are for guidance only and you should not change the dose that is prescribed by your doctor unless you have been instructed to do so:

Adults - Starting dose of 10mg once per day. This dose may be increased depending on results.

Children - Usage and dosage must be determined by the doctor.

Missed doses should be taken as soon as possible unless you are then close to your next dose. If you are close to your next dosage time then you should skip the missed dose and return to your usual schedule. Make a note of the missed dose to inform your doctor when you go for your next checkup. A missed dose may have an effect on the blood pressure results that your doctor takes.

Never take a double dose of this medication. You will be at risk of experiencing overdose symptoms.

It is important to tell your doctor about any medical conditions that you have or have had in the past. This is especially important with the following medical conditions:

Stopping the use of Betaxolol can provoke severe chest pain in these patients.

This medication should not be used with patients suffering from bradycardia, heart block or heart failure.

Diabetes, hyperthyroidism and hypoglycemia side effects can be covered up by the use of Betaxolol. Patients should be informed of other ways they can identify problems and should exercise extra caution.

  • Kidney disease

Removal of the medication from the body will be slower and the side effects can therefore be more pronounced in these patients.

  • Lung disease

Patients may experience increased difficulty in breathing when taking this medication.


Betaxolol blocks natural processes in the body to lower the blood pressure and as such can affect the body significantly. Before deciding to take this medication you should weigh the benefits against the risks and consider the following with your doctor:

Allergies - If you have ever had any unusual reactions to beta-blocking agents then you should not use this medication. You should also be wary if you have ever reacted badly to any other medication that you have received. Tell your doctor about any other allergies that you may have including allergies to dyes, food, animal and any other substances. Betaxolol can trigger severe allergic reactions in rare cases. If you experience this then you should seek immediate medical attention.

Pediatric - Safe and efficient use on children has not been established with this medication.

Geriatric - No problems with the use of this medication in the geriatric population are anticipated, but studies have not be carried out. Be cautious of age-related medical conditions that can impact the use of this medication, however.

Pregnancy - There is no controlled data in humans relating to the use of Betaxolol in pregnant women. While animal studies have shown fetus abnormalities at high levels of toxicity the risk is thought to be minimal. The benefits of Betaxolol should outweigh the risks to the fetus, although this should be discussed with your doctor.

Breastfeeding - Use caution when breastfeeding with use of this medication. Infants should be monitored for symptoms of exposure to Betaxolol when breastfeeding. Some beta-adrenergic blocking agents have been shown to cause adverse effects in infants. This medication will be extensively excreted through breast milk and will be passed to the child. Discuss the benefits of breastfeeding with your doctor and weigh them up against the potential risks of doing so when undergoing this treatment.


This medication should be stored in its original container until needed. Keep tablets in the blister pack until you are ready to take them.

Store in the closed container away from heat, moisture, and direct light.

Store at room temperature and prevent from freezing.

Always keep medication out of reach of children.

Do not keep any outdated or unused medicine. Your healthcare professional will be able to advise you on how best to dispose of any medicine that you have not used or has gone out of date.


Betaxolol is a beta-adrenergic blocking agent that works by preventing natural processes of the nervous system. This allows the blood vessels in the heart and arteries to relax and in doing so lowers the blood pressure in the patient.

This treatment is used to lower the risk of strokes, heart attack, heart failure and kidney failure in a patient with high blood pressure or hypertension. The use of Betaxolol will only temporarily lower the blood pressure in the patient and they will need to keep using the treatment in perpetuity to keep the blood pressure down.

This medication should be prescribed with additional advice on how to lower the blood pressure through healthier living. Steps that can be taken include reducing the amount of fat consumed, reducing the amount of salt consumed, losing weight and exercising. Lowering the blood pressure through healthy living will allow you to stop taking Betaxolol and will lower the risks of heart failure, heart attack, stroke and kidney failure.

Betaxolol has a significant number of interactions with other medications and as such, it is very important that you inform your doctor of all other medications that you are taking. You should also inform your doctor of any medical conditions that you have as these can also impact the use of this medication.

Betaxolol can be taken by pregnant women and the benefits of doing so should outweigh the risks of taking the medicine. Discuss this with your doctor and inform them if you are pregnant or may be soon.

Betaxolol will be excreted significantly in breast milk and will be passed on to a breastfeeding infant. You should discuss the risks of this with your doctor and any breastfeeding infants should be monitored for the effects of Betaxolol intake.
