Why do I feel cold after taking ibuprofen, and what should I do?

Generally, feeling cold after taking ibuprofen may be caused by factors such as drug overdose, side effects, or allergic reactions. Patients are advised to manage symptoms according to the specific situation. The details are as follows:

1. Drug Overdose

If a patient does not follow medical instructions and takes an excessive dose of ibuprofen or repeatedly uses it within a short period, it may lead to drug overdose, resulting in a significant drop in body temperature and feelings of coldness. It is recommended that patients keep warm and monitor their condition. If other discomforts occur or symptoms persist for a prolonged time, prompt medical attention is advised.

2. Drug Side Effects

Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID) that may cause certain side effects, including fever, chills, headache, and gastrointestinal discomfort. These side effects are generally mild. Patients are advised to rest adequately and maintain a light diet; symptoms usually resolve gradually.

3. Allergic Reaction

Some individuals may be allergic to ibuprofen, which could result in symptoms such as chills, rash, and rapid breathing. If signs of an allergic reaction appear, medication should be stopped immediately and medical help sought promptly. Patients should not self-administer antiallergy drugs, as this may lead to adverse outcomes.

In addition, other underlying causes may include emotional conditions such as depression or anxiety, worsening infection, hyperthyroidism, or malignancies. Patients experiencing discomfort should seek timely medical evaluation to avoid delayed treatment. Maintaining a light diet and adequate rest in daily life is also recommended.
