Betagan review

Betagan is generally prescribed to treat glaucoma and other diseases that result with extensive pressure in the eye. It can be prescribed as levobunolol ophthalmic. It is a beta blocker and is dispensed in a liquid form with the use of an eye dropper.

The dispensing eye dropper should never touch any surface. It comes sterilized and should remain that way in order to avoid infection. A contaminated eye dropper can cause a serious eye infection. In case of contamination, patients are urged to call the pharmacist for instructions on replacing or sterilizing the eye dropper.

The medication must remain in the eye and not travel down through the tear ducts. Thus, after application, patients should apply a gentle but constant pressure along the ridge of the nose and the corner of the eye while the medication is absorbed, about one minute.

The prescribing physician should take a thorough assessment of the patient’s medical history before prescribing this drug. Betagan may not be suitable for patients with asthma, chronic lung disease, diabetes, over active thyroid, very low heart rate, and heart disease, especially heart block, hypertension, and congestive heart failure. Some patients may require careful testing and monitoring while others will not be able to handle the medication at all.

Betagan has received a pregnancy risk rating category C from the American Food and Drug Administration. Betagan has not been proven or disproven to cause harm to a developing fetus. It has yet to be determined whether Betagan passes through the mother’s breast milk and can affect a nursing infant. Women who are pregnant, nursing, or who are likely to become pregnant should discuss the risks and the benefits before starting a prescription of Betagan.

Betagan should be taken according to the pharmacy’s directions. Patients should take a missed dose as soon as possible, unless it is almost time for the next scheduled dose. Patients should skip a missed dose if the doses would be too close together. Double doses of this medication can result in overdosing.

An overdose requires immediate emergency medical attention and may present with symptoms such as wheezing, shortness of breath, respiratory distress, slow heart rate, headache, dizziness, or heart attack.

Allergic reactions are a medical emergency and often happen within the first dose, but can take several doses to develop. Swelling of the face, lips, mouth, tongue, or throat, hives, itching, and respiratory difficulties are indications of an allergic reaction.

Side effects are common and rarely require medical help. Patients should discuss their side effects with their physician as part of follow up care. Common side effects include fatigue, fainting, burning, stinging, headaches, nausea, depression, irregular heart rate, slow heart rate, and low blood pressure.

In rare cases, side effects can be much more serious and present life threatening symptoms such as an asthma attack or the signs of congestive heart failure—chest pain, shortness of breath, and anxiety.

Not all medications, over the counter or prescription, or herbal supplemenents or vitamin supplements, can be taken with Betagan. Patients should inquire with the prescribing physician before making any changes to their medication. Using other eye medications or beta blockers which are taken orally can cause severe reactions and lead to an overdose.

Patients who wear contact lenses should ask their physician for special instructions regarding cleaning solution, removal of lenses, and when it is safe to reinsert the lens.
