Dizziness and nausea after taking levofloxacin

Generally, dizziness and nausea after taking levofloxacin may be caused by drug side effects, expired medication, or drug overdose. It is recommended to identify the specific cause and receive targeted treatment. The detailed analysis is as follows:

1. Drug Side Effects

Levofloxacin is a commonly used quinolone antibiotic. After entering the body, it may irritate the central nervous system or gastric mucosa, leading to side effects such as dizziness, diarrhea, nausea, and vomiting. In most cases, these symptoms gradually subside after discontinuation of the drug and usually do not require special treatment.

2. Expired Medication

If the medication has not been properly stored and becomes degraded or expired, its active ingredients may change or become contaminated. Once ingested, it may irritate the gastrointestinal mucosa and brain nerves, causing the aforementioned symptoms. In such cases, drink plenty of water to promote metabolism, and avoid taking this medication again.

3. Drug Overdose

Taking a higher dose than prescribed without medical guidance can also affect health, resulting in abdominal pain, dizziness, drowsiness, and other symptoms. It is recommended to take the medication as directed; if necessary, switch to an alternative medication under medical supervision.

In addition to the common causes mentioned above, dizziness and nausea could also result from hypoglycemia, anemia, insufficient cerebral blood supply, or other conditions. It is advisable to visit a hospital for appropriate diagnostic evaluations.
