Summary of Key Points

Betaxolol is a medication commonly prescribed for conditions such as high blood pressure, glaucoma, and certain heart-related issues. It belongs to a class of drugs known as beta-blockers, which work by reducing the heart’s workload and lowering blood pressure. Betaxolol is available in both oral tablet and eye drop forms.

How to Use Betaxolol Eye Drops and Oral Tablets

Betaxolol should be used exactly as prescribed by your healthcare provider. For Betaxolol eye drops, wash your hands before applying and avoid touching the dropper tip to any surface to prevent contamination. For oral tablets, you can take them with or without food, but try to take them at the same time each day. If you miss a dose, take it as soon as you remember, unless it’s close to your next scheduled dose. In that case, skip the missed dose and continue with your regular schedule. Do not double the dose to make up for a missed one. Always follow your doctor’s instructions, and if you have any questions, consult your healthcare provider. You can also schedule a telemedicine visit with us for further assistance.

Contraindications for Betaxolol

A contraindication is a specific condition or situation where a medication should not be used because it may cause harm. If you have any of the following conditions, avoid taking Betaxolol and discuss alternative treatments with your healthcare provider:

1. Severe bradycardia (slow heart rate): Betaxolol can further slow your heart rate, which could be dangerous if your heart is already beating too slowly.
2. Second or third-degree heart block: This condition occurs when the electrical signals in your heart are partially or completely blocked. Betaxolol can worsen this condition, leading to more serious heart problems.
3. Cardiogenic shock: This life-threatening condition happens when the heart cannot pump enough blood to meet the body’s needs. Betaxolol can decrease heart function, worsening this condition.
4. Severe asthma or chronic obstructive pulmonary disease (COPD): Betaxolol, as a beta-blocker, can narrow the airways, potentially worsening breathing problems in people with asthma or COPD.
5. Severe peripheral arterial disease: This condition affects blood flow to the limbs. Betaxolol can reduce circulation, worsening symptoms like pain or cramping in the legs.
6. Untreated pheochromocytoma: This rare adrenal gland tumor can cause high blood pressure. Betaxolol may not be safe unless the condition is properly managed with other medications.

Drug to Drug Interactions

Betaxolol can interact with other medications, potentially increasing side effects or reducing its effectiveness. It’s essential to inform your healthcare provider about all the medications you are taking, including over-the-counter drugs and supplements. Some key drug interactions include:

1. Calcium channel blockers (e.g., Verapamil, Diltiazem): These medications can slow your heart rate and lower blood pressure, increasing the risk of heart complications when combined with Betaxolol.
2. Clonidine (brand name: Catapres): Using Clonidine with Betaxolol may lead to a significant drop in both blood pressure and heart rate.
3. Antiarrhythmics (e.g., Amiodarone, Quinidine): These drugs treat irregular heartbeats but may increase the risk of bradycardia (a slow heart rate) when taken with Betaxolol.
4. Insulin or oral diabetes medications (e.g., Metformin, Glipizide): Betaxolol can mask the symptoms of low blood sugar, making hypoglycemia harder to recognize and treat.
5. Nonsteroidal anti-inflammatory drugs (NSAIDs) (e.g., Ibuprofen, Naproxen): These medications may reduce Betaxolol’s ability to lower blood pressure.

Betaxolol in Pregnancy

Is it safe to take Betaxolol during pregnancy?

Betaxolol is classified as a pregnancy category C drug by the FDA, meaning there isn’t enough research to confirm its safety during pregnancy. While animal studies suggest some risk to the fetus, there are no well-controlled studies in pregnant women. If you are pregnant or planning to become pregnant, it’s important to discuss the potential risks and benefits of Betaxolol with your healthcare provider. In some cases, the benefits of controlling high blood pressure or heart conditions may outweigh the potential risks to the baby.

Betaxolol while Breastfeeding

Is it safe to take Betaxolol while breastfeeding?

Betaxolol is excreted in breast milk, meaning it can pass to your baby. Although the amount transferred is generally low, it’s important to carefully weigh the risks and benefits. If you are breastfeeding, consult your healthcare provider to determine whether Betaxolol is the right choice for you. In some cases, an alternative medication may be recommended.

Estimated Cost of Betaxolol Medication

The cost of a 30-day supply of Betaxolol without insurance can vary depending on the pharmacy and location. With a GoodRx coupon, the estimated price for a 30-day supply of Betaxolol (10 mg tablets) typically ranges from $30 to $50. Prices may differ, so it’s a good idea to check with your local pharmacy or use a discount service like GoodRx for the most accurate pricing.

Possible Alternatives to Betaxolol

If Betaxolol isn’t suitable for you, there are other treatment options available depending on your condition. Always consult your healthcare provider before making any changes to your treatment plan. You can also consult one of our providers via telemedicine for personalized advice.

1. Glaucoma: Alternatives include other beta-blocker eye drops like Timolol or prostaglandin analogs such as Latanoprost. In some cases, laser therapy or surgery may be considered.
2. Ocular hypertension: Similar to glaucoma, alternatives include prostaglandin analogs, alpha agonists, or carbonic anhydrase inhibitors.
3. Hypertension: Lifestyle changes, such as reducing salt intake, exercising regularly, and managing stress, can help. Other medications include ACE inhibitors (e.g., Lisinopril), calcium channel blockers (e.g., Amlodipine), or diuretics (e.g., Hydrochlorothiazide).
4. Heart failure: ACE inhibitors, ARBs (e.g., Losartan), or diuretics may be prescribed. Lifestyle changes, such as reducing sodium intake and engaging in regular physical activity, are also important.
5. Angina: Other beta-blockers like Metoprolol or calcium channel blockers may be used. Nitroglycerin is another option for relieving chest pain.
6. Arrhythmias: Antiarrhythmic drugs like Amiodarone or procedures like electrical cardioversion may be considered. Lifestyle changes, such as reducing caffeine intake, can also help manage symptoms.
7. Migraine: Preventive medications like Topiramate or Amitriptyline may be alternatives. Lifestyle adjustments, such as avoiding known triggers and managing stress, can reduce the frequency of migraines.
8. Anxiety: Cognitive-behavioral therapy (CBT) and relaxation techniques may be beneficial. Medications like SSRIs (e.g., Sertraline) or benzodiazepines (e.g., Lorazepam) may also be considered.
9. Hyperthyroidism: Antithyroid medications like Methimazole or radioactive iodine treatment may be alternatives. Beta-blockers are often used to control symptoms while waiting for other treatments to take effect.
10. Essential tremor: Other beta-blockers like Propranolol or anticonvulsants such as Primidone may be used. In some cases, deep brain stimulation (DBS) surgery may be an option.

Recent Updates on Betaxolol Research

Recent studies have explored Betaxolol’s potential uses beyond its traditional roles in treating glaucoma and hypertension. For example, ongoing research is investigating its possible neuroprotective effects in glaucoma patients, which could help slow vision loss. Additionally, some studies are examining Betaxolol in combination with other medications to enhance its effectiveness in treating cardiovascular conditions. However, more research is needed to confirm these findings.

It’s important to stay informed about the latest research and discuss new treatment options with your healthcare provider. If you have questions about Betaxolol or other medications, our telemedicine providers are available to help you understand your options and make informed decisions about your health.
