Afrezza is utilized primarily to manage blood sugar levels during mealtime, offering a rapid-acting insulin option for individuals with diabetes mellitus. It is particularly beneficial for addressing postprandial glucose spikes, which commonly occur after meals.

Afrezza is administered just before or at the start of a meal to help control blood sugar levels during and after eating. Its rapid onset of action closely mimics the body’s natural insulin response to food intake, thereby aiding in the regulation of glucose levels.

Individuals with type 1 diabetes, who lack the ability to produce insulin, can use Afrezza in combination with long-acting insulin to manage their blood sugar throughout the day. Its rapid absorption into the bloodstream makes it effective in controlling post-meal glucose excursions.

Afrezza is also approved for use in adults with type 2 diabetes. It can be used either alone or in combination with other antidiabetic medications, such as oral glucose-lowering drugs or long-acting insulin, to improve glycemic control. This flexibility makes Afrezza a valuable treatment option for individuals with type 2 diabetes who require additional insulin support to manage their blood sugar levels.

How it works

Afrezza works by delivering insulin directly to the lungs through inhalation. Unlike traditional injectable insulins, which are administered subcutaneously and take time to be absorbed into the bloodstream, Afrezza’s inhaled insulin formulation allows for rapid absorption and onset of action.

When Afrezza is inhaled, the powdered insulin particles enter the lungs and are quickly absorbed into the bloodstream through the alveoli, tiny air sacs in the lungs where gas exchange occurs. From there, insulin enters the systemic circulation and begins to lower blood sugar levels.

The rapid absorption of Afrezza mimics the body’s natural insulin response to food intake. In individuals without diabetes, the pancreas releases insulin in response to rising blood sugar levels after meals, facilitating the uptake of glucose into cells for energy or storage. Afrezza provides a similar rapid-acting insulin effect, helping to control postprandial glucose spikes and maintain blood sugar levels within the target range.

Common side effects 

• Hypoglycemia (low blood sugar): This can occur if the dose of Afrezza is too high or if not enough food is consumed after administration.
• Cough: Some individuals may experience a cough after inhaling Afrezza. 
• Throat irritation: Inhalation of Afrezza may cause irritation or soreness in the throat, which typically resolves over time.

Serious side effects 

• Allergic reactions: Some individuals may experience allergic reactions to Afrezza, which can range from mild to severe and may include symptoms such as rash, itching, swelling, or difficulty breathing.
• Decline in lung function: Afrezza may cause a decline in lung function, particularly in patients with underlying lung diseases such as asthma or chronic obstructive pulmonary disease (COPD).

Patients should report any side effects they experience while using Afrezza to their healthcare provider promptly. It’s essential to weigh the benefits of glycemic control against the potential risks of treatment and to work closely with a healthcare provider to manage any side effects effectively.

Before starting treatment with Afrezza, patients should be aware of certain precautions and warnings to ensure safe and effective use of the medication.

Afrezza should be used with caution in individuals with a history of lung disease, such as asthma or chronic obstructive pulmonary disease (COPD). It may exacerbate respiratory symptoms and lead to a decline in lung function. Patients should undergo regular monitoring of lung function while using Afrezza and discontinue treatment if significant declines are observed.

Afrezza is not recommended for use in individuals who smoke or have recently quit smoking. Smoking may increase the risk of respiratory complications with Afrezza and could impair its effectiveness.

As with any insulin therapy, Afrezza can cause hypoglycemia (low blood sugar). Patients should be educated about the signs and symptoms of hypoglycemia and how to treat it promptly. Adjustments to the dose of Afrezza or other antidiabetic medications may be necessary to reduce the risk of hypoglycemia.

Afrezza, like other medications, may interact with certain drugs, potentially affecting its efficacy or increasing the risk of adverse effects. It’s essential for patients to inform their healthcare provider about all medications they are taking, including prescription, over-the-counter, and herbal supplements, to avoid potential drug interactions.

Afrezza dosing is individualized based on factors such as meal size, blood sugar levels, and insulin sensitivity. It’s essential for patients to work closely with their healthcare provider to determine the most appropriate dosage regimen for their needs.

The recommended starting dose of Afrezza for adults with type 1 or type 2 diabetes is typically based on body weight and is administered before each meal. Healthcare providers may adjust the initial dose based on factors such as glycemic control and insulin sensitivity.

Patients should monitor their blood sugar levels regularly and report any significant changes to their healthcare provider. Dosage adjustments may be necessary based on factors such as changes in diet or exercise habits, illness, or other medications that may affect blood sugar levels.

Afrezza is administered using a small handheld inhaler device. Patients should receive proper training on inhaler technique and follow the prescribed dosing instructions carefully to ensure effective delivery of insulin.

Afrezza is available by prescription only and should be used under the guidance of a healthcare provider experienced in the management of diabetes. Patients cannot obtain Afrezza over-the-counter and must consult their healthcare provider to determine if Afrezza is an appropriate treatment option for their condition. Healthcare providers will assess the patient’s medical history, current medications, and individual needs to prescribe the most suitable dosage and administration regimen.Patients should follow their healthcare provider’s instructions for proper use of Afrezza and report any concerns or side effects promptly during the course of treatment.
