Long-Term Use of Duasma: Risks of Glaucoma and Eye Pressure - Pulmonology

More Info

Duasma, known generically as budesonide/formoterol, is an inhaled medication commonly prescribed for asthma and chronic obstructive pulmonary disease (COPD). It combines a corticosteroid (budesonide) with a long-acting beta-agonist (formoterol) to help reduce inflammation and relax the airways. While your doctor has assured you that long-term use of Duasma is generally safe and that the dosage is low, it is understandable to have concerns regarding potential side effects, particularly those related to eye health, such as glaucoma and increased intraocular pressure.

Corticosteroids, including budesonide, are known to have a potential side effect of increasing intraocular pressure, which can lead to glaucoma, especially when used in high doses or over extended periods. However, the risk associated with inhaled corticosteroids is significantly lower compared to systemic corticosteroids (those taken orally or injected). This is primarily due to the lower systemic absorption of inhaled medications, which means that less of the drug enters the bloodstream and reaches other parts of the body, including the eyes.

The warning about glaucoma and increased eye pressure in the medication's information is a precautionary measure. It serves to inform patients and healthcare providers of the potential risks, particularly for those who may already have risk factors for glaucoma, such as a family history of the disease, existing eye conditions, or other health issues. In your case, if you do not have any pre-existing conditions that predispose you to glaucoma, the likelihood of developing these issues from long-term use of Duasma is relatively low.

It is also important to consider that the dosage of the medication plays a crucial role in the risk of side effects. Since your doctor has prescribed a low dose, this further minimizes the risk. Regular monitoring of your eye health, especially if you have concerns or if you notice any changes in your vision, is advisable. If you experience symptoms such as blurred vision, seeing halos around lights, or persistent eye discomfort, you should consult with your healthcare provider promptly.

In summary, while there is a theoretical risk of increased intraocular pressure and glaucoma with long-term use of inhaled corticosteroids like Duasma, the actual risk is quite low, particularly at low doses. It is essential to maintain open communication with your healthcare provider about any concerns you may have and to undergo regular eye examinations, especially if you are using the medication for an extended period. Your doctor can help monitor your eye health and make any necessary adjustments to your treatment plan if needed.
