Precautions and Warnings With Betaxolol

Specific Betaxolol Precautions and Warnings

Some warnings and precautions to be aware of prior to taking this drug include the following:
  • Beta blockers can worsen breathing problems like asthma or COPD. If you have breathing problems, check with your healthcare provider before taking betaxolol. This can be a problem even for betaxolol eye drops.
  • As with all oral beta blockers, you should not abruptly stop taking betaxolol tablets, as serious problems (including heart attacks) may result. Your healthcare provider will advise you about how to safely stop taking this medication. It is usually recommended to slowly reduce the dose over a period of one to two weeks, with careful monitoring, and to minimize physical activity during this time. Let your healthcare provider know if you develop chest pain or any other problems while stopping betaxolol.
  • Beta blockers can mask some of the symptoms of low blood sugar (hypoglycemia), particularly the "racing heart" feeling. This can cause serious problems for people with diabetes, who need to be able to sense that they have low blood sugar (in order to correct it before it becomes life-threatening).
  • Like all beta blockers, betaxolol can worsen heart failure in some situations. However, beta blockers are also useful for the treatment of heart failure. If you have heart failure, your healthcare provider may need to monitor you very closely while you take betaxolol. Let your healthcare provider know immediately if your heart failure symptoms seem to worsen.
  • Betaxolol may worsen myasthenia gravis symptoms or may even potentially cause myasthenia gravis. Let your healthcare provider know if you develop symptoms of this problem, such as muscle weakness, double vision, or a droopy eyelid.
  • If you will be having surgery, make sure your surgeon and anesthesiologist know you take betaxolol, as it may affect the choice of medications used during the surgery.
  • Beta blockers can mask some of the symptoms of an overactive thyroid (hyperthyroidism). Stopping betaxolol suddenly could cause symptoms of a "thyroid storm" (a sudden and severe worsening of hyperthyroidism symptoms).


  • Betaxolol could potentially worsen psoriasis; this must be considered before this medication is used by people with this condition.
  • Betaxolol should not be used in people with untreated pheochromocytoma.
  • Like other beta blockers, betaxolol may be associated with the development of lupus. 


  • Betaxolol can potentially interact with many other medications (see Drug Interactions With Betaxolol).
  • The kidneys and liver help remove betaxolol from the body. If you have kidney or liver disease, your healthcare provider may need to monitor your response to betaxolol more closely (and a lower betaxolol dosage may be recommended).
  • Betaxolol could potentially cause problems for people with poor blood circulation in the brain (such as people who have had a stroke or transient ischemic attack). If you have had such problems in the past, check with your healthcare provider before taking betaxolol.
  • If you have an anaphylactic allergy (the type that affects the entire body and often interferes with breathing), betaxolol can make you more sensitive to the allergen and may make the usual treatments (such as epinephrine or an EpiPen®) less effective.
  • Betaxolol is considered a pregnancy Category C medication. This means that it may not be safe for use during pregnancy, although the full risks are not currently known (see Betaxolol and Pregnancy).
  • Betaxolol passes through breast milk in humans. Therefore, if you are breastfeeding or plan to start breastfeeding, discuss this with your healthcare provider prior to taking the drug (see Betaxolol and Breastfeeding).
