From the Guidelines
Dysgeusia is not a definitive indication to discontinue Clarithromycin therapy, unless it significantly impacts the patient's quality of life or nutritional intake. The management of Helicobacter pylori infection, as outlined in the Maastricht IV/Florence Consensus Report 1, does not specifically address dysgeusia as a reason to discontinue clarithromycin. However, it does emphasize the importance of completing the full prescribed course of treatment to ensure effective eradication of the infection.
Some key points to consider when managing dysgeusia in patients taking clarithromycin include:
- The side effect is usually temporary and resolves after completing the treatment course
- If the dysgeusia is severe, it may be necessary to discuss alternative treatment options with a healthcare provider
- The use of sugar-free mints or gum, good oral hygiene, and staying well-hydrated may help manage the side effect
- In areas with high clarithromycin resistance, alternative treatment regimens such as bismuth-containing quadruple treatments or sequential treatment may be recommended 1
It's essential to weigh the benefits of completing the prescribed course of clarithromycin against the potential impact of dysgeusia on the patient's quality of life and nutritional intake. Unless the dysgeusia is severe, it is generally recommended to continue the full prescribed course of clarithromycin to ensure effective treatment of the underlying infection. If the taste disturbance is severe, healthcare providers may consider alternative antibiotics, such as azithromycin, which may have a different side effect profile 1.
From the Research
Dysgeusia and Clarithromycin Therapy
- Dysgeusia, an unpleasant alteration in taste, has been reported as a side effect of clarithromycin therapy 2, 3, 4, 5.
- In a study on clarithromycin-amoxycillin therapy for Helicobacter pylori infection, 8 out of 29 patients experienced dysgeusia, but none discontinued therapy due to this side effect 2.
- Another study found that 21.1% of patients experienced a metallic taste, but none discontinued medication 4.
- A systematic review of drug-related dysgeusia found that clarithromycin was one of the drugs correlated with dysgeusia, but the quality of evidence was low in most reviewed studies 3.
- The pharmacokinetics and tolerability of extended-release clarithromycin found that abnormal taste was one of the most frequently reported adverse events, but the incidence was comparable to the immediate-release formulation 5.
Discontinuation of Clarithromycin Therapy
- There is no evidence to suggest that dysgeusia is a indication to discontinue clarithromycin therapy 2, 4.
- In fact, studies have shown that clarithromycin therapy can be effective and well-tolerated, even in patients who experience dysgeusia 2, 4, 5.
- The decision to discontinue clarithromycin therapy should be based on the severity of side effects and the clinical judgment of the healthcare provider 3, 5.
