What should I do if my body temperature rises higher after receiving a fever-reducing injection?
After receiving a fever-reducing injection, body temperature may rise further, which could be related to factors such as dehydration, ineffective medication, insufficient drug dosage, drug allergy, or concurrent viral infection. It is important to seek medical attention and follow the doctor's recommendations for appropriate treatment.
1. Dehydration
If the patient is significantly dehydrated, they may be unable to sweat effectively, impairing the body’s ability to release heat and reducing the effectiveness of the fever-reducing injection. It is recommended to promptly replenish fluids and adjust the indoor temperature accordingly.
2. Medication Not Yet Effective
Due to individual differences in physical condition and baseline body temperature, it may take some time—typically 1 to 2 hours—after the injection for fever symptoms to gradually subside. During this period, high fever might still occur. Monitor body temperature and mental status closely. If there is no improvement, seek medical help promptly.
3. Insufficient Drug Dosage
The dose of the antipyretic injection may have been too low to produce a noticeable effect. It is recommended to adjust the dosage under a physician’s guidance.
4. Drug Allergy
The patient may be allergic to certain components of the medication, triggering an inflammatory response that increases body temperature. This may also be accompanied by rashes, skin itching, or other discomforts. Antiallergic medications such as cetirizine hydrochloride tablets, loratadine tablets, or ebastine tablets may be used as directed by a doctor.
5. Concurrent Viral Infection
Fever caused by a viral infection will not be controlled by fever-reducing injections alone, as these do not inhibit the virus itself. Body temperature may even increase after the injection. Under medical supervision, oral antiviral medications such as oseltamivir phosphate capsules, acyclovir tablets, or ribavirin tablets may be prescribed to suppress viral replication.
It is advised to visit a hospital promptly for relevant examinations. Once the underlying cause is identified, follow the doctor's instructions for proper management. During treatment, maintain a light diet and drink plenty of warm water to support recovery.
