Unable to stand due to limb weakness after intravenous ceftriaxone infusion

Generally, weakness in the limbs and inability to stand after receiving cefalosporin injection may be caused by poor sleep quality, rapid infusion rate, adverse drug reactions, hypoglycemia, or myasthenia gravis, among other factors. Appropriate treatment should be administered based on the specific cause. Detailed analysis is as follows:

1. Poor Sleep Quality

If a patient suffers from insomnia or excessive fatigue, it may negatively affect the body and lead to limb weakness. This condition is generally unrelated to the administration of cefalosporin antibiotics. It is recommended to drink a cup of warm milk before bedtime each night to promote better sleep, and avoid staying up late.

2. Rapid Infusion Rate

Infusing fluids too quickly may suddenly increase blood volume within a short time, leading to elevated blood pressure and symptoms such as dizziness, headache, and general fatigue. The injection rate should not be too fast. Usually, no special treatment is required—symptoms can be relieved simply by resting for a period of time.

3. Adverse Drug Reaction

If limb weakness occurs after receiving cefalosporin antibiotics, it may be due to an allergic reaction caused by the medication. In some cases, symptoms such as difficulty breathing and generalized rash may also appear. It is recommended to rest appropriately and, under medical guidance, take vitamin C or medications such as loratadine tablets or cetirizine tablets to alleviate symptoms.

4. Hypoglycemia

Fasting during intravenous infusion, combined with the administration of fluids such as normal saline, increases blood volume and dilutes blood glucose levels, potentially worsening hypoglycemia and causing symptoms like dizziness, fatigue, and generalized weakness. Treatment may include medications such as furosemide tablets or compound reserpine triamterene tablets, taken as directed by a physician.

5. Myasthenia Gravis

This is a chronic autoimmune neuromuscular disorder characterized primarily by muscle weakness and easy fatigability. The use of cefalosporin antibiotics may exacerbate existing myasthenia gravis or trigger symptom onset. Patients should receive treatment under a doctor’s supervision, which may include medications such as pyridostigmine bromide tablets or cyclophosphamide compound tablets.

In summary, if any of the above symptoms occur, it is important to inform the doctor promptly. Additionally, patients should avoid alcohol and all alcoholic beverages and foods after receiving cefalosporin injections, including dishes cooked with cooking wine, to prevent disulfiram-like reactions.
