Adverse Effects of Arikayce: An Overview and Strategies for Mitigation
Arikayce is a brand-name inhalation suspension prescribed for treating a certain bacterial lung infection known as Mycobacterium avium complex (MAC) lung disease. While it can be effective, it's important to be aware of its potential long-term risks and considerations.
Primarily, Arikayce is associated with respiratory adverse reactions and hypersensitivity. Notable long-term side effects reported include:
- Hypersensitivity pneumonitis, an inflammation of the lung tissue due to an immune reaction.
- Hemoptysis, or coughing up blood.
- Bronchospasm, a narrowing of the airways causing breathing difficulty.
- Exacerbations of underlying pulmonary diseases, such as chronic obstructive pulmonary disease (COPD) or bronchiectasis, are more common in patients on Arikayce plus background treatment compared to background treatment alone.
- Serious hypersensitivity reactions and anaphylaxis, which can include symptoms like hives, swelling of lips/tongue/uvula, respiratory distress (shortness of breath, wheezing), gastrointestinal symptoms, and cardiovascular shock.
In clinical trials and post-marketing experience, these respiratory side effects are the primary long-term safety concerns. Therefore, Arikayce treatment should be closely monitored for signs of pulmonary reactions or hypersensitivity.
Additional context from pharmacokinetic studies shows that liposomal amikacin, the active ingredient in Arikayce, accumulates preferentially in lung tissues. This may explain the localized lung-related side effects but also supports its targeted efficacy.
Before starting treatment with Arikayce, it's crucial to inform your doctor about any medical conditions you have, including kidney problems, nerve conditions such as myasthenia gravis, and genetic hearing conditions. If you have hearing problems or are pregnant, can become pregnant, or are breastfeeding, talk with your doctor before starting Arikayce.
Some over-the-counter pain medications may not be safe to take with Arikayce due to the risk of certain serious side effects. It's important to talk with your doctor or pharmacist before starting any OTC medications to ensure they are safe to take with Arikayce.
Common side effects reported with Arikayce include skin rash, weight loss, increased sputum, cough, diarrhea, fatigue, and changes in voice or hoarseness. Mild side effects reported include fever, muscle or joint pain, mouth or throat irritation or pain, chest discomfort, headache, and mild allergic reaction.
For mild symptoms of an allergic reaction, call your doctor right away. For serious symptoms, immediately call 911 or your local emergency number. If you develop diarrhea that's bothersome to you, talk with your doctor. They may recommend taking an OTC medication, such as loperamide (Imodium).
It's worth noting that Arikayce does not have a generic version available. Always ensure you are taking the prescribed brand-name medication to maintain proper treatment.
In rare cases, diarrhea can be a symptom of an allergic reaction. If you experience this, seek immediate medical attention.

- When taking Arikayce, be aware of its potential long-term risks, such as hypersensitivity pneumonitis, hemoptysis, bronchospasm, exacerbations of underlying pulmonary diseases, and serious hypersensitivity reactions or anaphylaxis.
- Given the accumulation of liposomal amikacin, the active ingredient in Arikayce, in lung tissues, it's essential to closely monitor the treatment for signs of pulmonary reactions or hypersensitivity.
- Before starting Arikayce, inform your doctor about any medical conditions, including kidney problems, nerve conditions, and genetic hearing conditions, as these may affect your treatment.
- Take caution when combining Arikayce with over-the-counter pain medications, as some may not be safe to take with it due to the risk of certain serious side effects.
- Common side effects of Arikayce include skin rash, weight loss, increased sputum, cough, diarrhea, fatigue, and changes in voice or hoarseness, but if you experience mild allergic reactions, fever, muscle or joint pain, mouth or throat irritation or pain, chest discomfort, headache, or diarrhea that's bothersome, consult your doctor for proper management.
