Introduction
In general, if a person sweats after taking antipyretic medication but then experiences fever again, it may be related to factors such as reduced drug efficacy, influenza, pneumonia, tuberculosis, or hyperthyroidism. Treatment can include daily care and medical interventions. It is advisable to maintain healthy lifestyle habits and avoid consuming spicy or irritating foods such as Sichuan pepper, chili peppers, and garlic, as these may hinder recovery.

In general, if a person sweats after taking antipyretic medication but then experiences fever again, it may be related to factors such as reduced drug efficacy, influenza, pneumonia, tuberculosis, or hyperthyroidism. Treatment can be carried out through daily care, medication, and other interventions. Specific analyses are as follows:

1. Reduced Drug Efficacy

After entering the body, antipyretic drugs undergo processes including absorption, distribution, metabolism, and excretion. Over time, the drug concentration in the body gradually decreases. When the concentration falls below the effective therapeutic level, the drug may no longer effectively suppress the body's temperature regulation center, leading to a rise in body temperature again. It is recommended to take the antipyretic again at appropriate intervals according to the instructions, in order to maintain an effective drug concentration.

2. Influenza

Influenza is a respiratory illness caused by infection with the influenza virus. If the patient has not fully recovered or becomes reinfected with another strain of the influenza virus, recurrent fever may occur. While taking antipyretics, patients should also take antiviral medications such as oseltamivir phosphate capsules or ribavirin tablets for treatment.

3. Pneumonia

If pneumonia is not completely treated, symptoms are not fully resolved, or the patient is reinfected with another pathogen, persistent fever may result. Additionally, pneumonia can cause lung tissue damage and inflammation, which may lead to recurrent fever. Patients should drink plenty of water and urinate frequently, and follow medical advice to use medications such as sodium penicillin for injection or cefotaxime sodium for injection.

4. Tuberculosis

Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis. If the disease is not fully cured or recurs, it may lead to recurring fever. While managing fever, patients can take anti-tuberculosis drugs such as isoniazid tablets or rifampicin tablets.

5. Hyperthyroidism

In patients with hyperthyroidism, excessive secretion of thyroid hormones accelerates metabolism and increases heat production, which may also lead to fever recurrence even after taking antipyretics. Under medical guidance, patients can take medications such as propylthiouracil tablets, carbimazole tablets, or metoprolol tartrate tablets for treatment.

Maintain healthy lifestyle habits in daily life, and avoid consuming spicy and irritating foods such as Sichuan pepper, chili peppers, and garlic, as these may impair recovery.

Can I hug someone who has norovirus?
Under normal circumstances, norovirus mainly spreads through close contact. During symptom onset, the virus present in saliva, sweat, or vomit may remain on the body surface. Hugging at this time can easily lead to infection via skin contact or respiratory droplets, especially for individuals with weaker immune systems who face a higher risk of infection, potentially leading to symptoms such as vomiting and diarrhea.
