Drug Interactions With Betaxolol

Betaxolol Interactions Explained

The following sections explain in detail the potentially negative interactions that can occur when betaxolol is combined with any of the drugs listed above.
 
Alpha Blockers
Combining betaxolol with an alpha blocker can increase the risk of dangerously low blood pressure (hypotension). Check with your healthcare provider before combining such medications. This is probably more of a concern with betaxolol tablets (Kerlone), rather than betaxolol eye drops (Betoptic).
 
Calcium Channel Blockers
Combining betaxolol with certain calcium channel blockers may cause dangerously low blood pressure and (for verapamil or diltiazem) a slow heart rate (bradycardia) or heart failure. You may need to be monitored very closely if you take these medications together. In some cases, it is not recommended to combine betaxolol with a calcium channel blocker. This is probably more of a concern with betaxolol tablets (Kerlone), rather than betaxolol eye drops (Betoptic).
 
Certain Arrhythmia Medications
Combining betaxolol with certain arrhythmia medications may cause a dangerously slow heart rate (bradycardia). You may need to be monitored very closely if you take these medications together. In some cases, it is not recommended to combine betaxolol with an arrhythmia medication. This is probably more of a concern with betaxolol tablets (Kerlone), rather than betaxolol eye drops (Betoptic).
 
Clonidine
If you take both clonidine and betaxolol, stopping clonidine (without stopping the betaxolol) could increase the risk of dangerously high blood pressure, strokes, and other serious problems. It is advised to stop taking betaxolol several days before you gradually reduce the dose of clonidine. Do not attempt this without the approval and supervision of your healthcare provider. This is probably more of a concern with betaxolol tablets (Kerlone), rather than betaxolol eye drops (Betoptic).
