Introduction
In general, levofloxacin tablets, as a quinolone antibiotic, may cause side effects after administration, including gastrointestinal discomfort, central nervous system reactions, musculoskeletal abnormalities, skin allergic reactions, and effects on liver and kidney function. During treatment with levofloxacin tablets, the dosage and duration of therapy must be strictly followed as prescribed by a physician; patients should not adjust the dose or extend the treatment period on their own.
Generally, as a quinolone antibiotic, Levofloxacin Tablets may cause several side effects after administration, including gastrointestinal discomfort, central nervous system reactions, musculoskeletal abnormalities, skin allergic reactions, and effects on liver and kidney functions. Detailed analysis is as follows:
1. Gastrointestinal discomfort: Some patients may experience symptoms such as nausea, vomiting, diarrhea, abdominal pain, and loss of appetite after taking the medication, primarily due to the drug's irritation to the gastrointestinal mucosa. These symptoms are usually mild, and most people can tolerate them. Taking the medication after meals may help alleviate these discomforts.
2. Central nervous system reactions: A few patients may experience dizziness, headache, insomnia, or anxiety. In severe cases, symptoms such as restlessness and confusion may occur. Patients with a history of epilepsy or other central nervous system diseases should use this medication with particular caution.
3. Musculoskeletal abnormalities: This medication may affect cartilage development, leading to joint pain, muscle aches, and even severe conditions such as tendonitis or tendon rupture, especially in elderly patients or those receiving corticosteroid therapy who are at higher risk.
4. Skin allergic reactions: Some patients with allergic constitutions may develop symptoms such as rash, itching, and skin erythema. Severe reactions may include allergic dermatitis and angioneurotic edema. If skin abnormalities occur, the medication should be discontinued immediately to prevent worsening of the allergic reaction.
5. Effects on liver and kidney function: Long-term or high-dose use of this medication may cause certain damage to liver and kidney function, manifesting as abnormal liver or kidney function indicators. Regular monitoring of liver and kidney function is necessary during treatment.
During the course of taking Levofloxacin Tablets, it is essential to strictly follow medical instructions regarding dosage and duration of treatment. Do not adjust the dose or extend the treatment period without authorization. Additionally, avoid taking the medication with drugs or foods containing metal ions, as this may affect drug efficacy. Maintain a light diet and drink plenty of water to promote drug metabolism.
