How long does the bitter taste in the mouth last after receiving intravenous anti-inflammatory fluids?

After receiving intravenous anti-inflammatory fluids, a bitter taste in the mouth is common and usually gradually disappears once the medication has been fully metabolized.

A bitter taste after IV infusion is a normal phenomenon. After the infusion, drugs may be secreted into the oral cavity through the salivary glands, causing a bitter sensation. It could also result from an imbalance in the normal oral flora. For example, gastrointestinal side effects of medications such as metronidazole or clindamycin can cause oral discomfort. Anti-inflammatory drugs may irritate the digestive system, affect gastrointestinal mucosa, and stimulate secretion of digestive fluids, leading to a bitter taste and altered taste perception. This is caused by the medication and does not pose any harm to the body. The bitter taste will gradually fade after the drug is eliminated.

To manage the bitter taste after IV anti-inflammatory treatment, probiotics can be taken to help regulate the body, and drinking more water can promote drug excretion. Once the medication is metabolized, the body will return to normal. Eating sweets such as biscuits may also help relieve the bitter taste. However, if the same medication is used in future IV treatments without changing the drug, the bitter taste is likely to recur.
