Medications can cause halitosis (bad breath) through intra-oral or extra-oral effects. Understanding these drug-induced causes is vital for effective diagnosis and management by healthcare providers.
Area of Science:
- Pharmacology
- Oral Medicine
- Halitosis Research
Background:
- Halitosis significantly impacts social, psychological, and emotional well-being.
- Effective diagnosis and management of halitosis are crucial for healthcare providers.
Purpose of the Study:
- To review medications that may cause halitosis as a side effect.
- To update knowledge on drug-induced halitosis for clinical application.
Main Methods:
- Conducted a literature review of PubMed and EMBASE/OVID databases.
- Focused on systematic reviews and literature published between 2020 and 2025.
Main Results:
- Identified medications causing extra-oral halitosis, including ranitidine, cysteamine, antifungals, aspirin, and others.
- Intra-oral halitosis is linked to medications causing xerostomia and medication-related osteonecrosis of the jaw (MRONJ).
Conclusions:
- Multiple medication classes can induce intra- or extra-oral halitosis.
- Further research is needed to elucidate specific mechanisms and monitor halitosis as an independent side effect.
- Clinicians should consider recreational drugs as potential causes of halitosis.
