Fever is one of the body’s natural defense mechanisms against infection. When viruses like the dengue virus enter the body, the immune system raises the internal temperature to make it harder for these pathogens to survive and replicate.
However, while fever helps fight infection, it can also lead to discomfort, fatigue, and dehydration. These are symptoms frequently seen in dengue and other viral illnesses across Latin America.
This is where ibuprofen, a trusted and widely available over-the-counter medication for fever relief, plays a crucial role.
What Is Ibuprofen and Why Is It So Widely Used in Latin America?

Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) commonly used to reduce fever, relieve pain, and control inflammation. It was developed in the 1960s by British scientist Dr. Stewart Adams and his team at the Boots Pure Drug Company.Ibuprofen was designed as a safer and more effective alternative to aspirin.
Since then, it has become one of the most widely used fever and pain medications worldwide, thanks to its proven efficacy and relatively mild side-effect profile when taken as directed.
In Latin America, ibuprofen is easily available over the counter and distributed under popular global and regional brand names such as Advil®, Motrin®, Dalsy®, and Nurofen®. Many local pharmaceutical companies also manufacture generic ibuprofen, ensuring it remains affordable and accessible across pharmacies, hospitals, and community health centers.
In countries like Mexico, Colombia, Brazil, and Argentina, ibuprofen is a go-to medication for managing fever, headache, and muscle pain caused by common viral infections such as dengue.
Its widespread availability allows families to treat mild symptoms at home, while public health authorities focus on vector control and disease prevention efforts across the region.
How Ibuprofen Works to Reduce Fever and Inflammation

- Blocks prostaglandin production
Ibuprofen inhibits the cyclooxygenase enzymes (COX-1 and COX-2), which are responsible for converting arachidonic acid into prostaglandins, the molecules that trigger inflammation, fever, and pain. By blocking COX activity, ibuprofen reduces prostaglandin levels, effectively interrupting the body’s fever and pain signaling pathways. - Resets the hypothalamus
With fewer prostaglandins stimulating the brain, the hypothalamus (the body’s internal thermostat) lowers its temperature “set point” back toward normal. This allows the body to release excess heat through sweating and improved blood circulation, helping to naturally cool down the system. - Relieves fever symptoms
As body temperature stabilizes, symptoms like chills, headache, muscle pain, and fatigue begin to subside. This provides comfort and supports faster recovery, particularly during infections such as dengue, influenza, or common viral fevers.
Through this mechanism of action, ibuprofen not only reduces fever and inflammation but also enhances overall well-being, making it a key medication for managing viral illness symptoms across Latin America.
Popular Ibuprofen Brands in Latin America

Across Latin America, pharmacies carry both international and locally manufactured brands of ibuprofen, making it one of the most accessible over-the-counter medications for fever and pain relief.
Recognizing these brands helps consumers choose trusted ibuprofen products, especially since packaging, brand names, and dosage strengths can vary between countries.
Below are some of the most common ibuprofen brands available in Latin America, reflecting the region’s diverse pharmaceutical market and commitment to providing affordable fever and pain management options.
Brand | Countries / Regions | Notes |
Advil | Brazil, Colombia, Mexico, others | One of the most recognized global brands. Often available in tablets, caplets, liquid forms. |
Actron | Argentina, Uruguay, Chile, Mexico | Popular for pain relief, sometimes marketed in formulations for rapid action (“rápida acción”) or combined with caffeine. |
Ibupirac | Argentina, Uruguay | Local generics/brands; comes in various strengths, including “Ibupirac Flex”. |
Motrin | Chile, Colombia, Peru, Venezuela | Known internationally; available in tablets, pediatric suspension. |
Maxigesic IV (Paracetamol + Ibuprofen) | Colombia, Peru, Chile, Ecuador, Bolivia, Uruguay, plus Central America & Caribbean countries | This is a more specialized product — an intravenous formulation, often used in hospital settings rather than OTC. |
Genfar | Chile, Ecuador, Peru, Paraguay, Central America & some Caribbean countries | A generic/local manufacturer brand, widely distributed across Latin America. |
Elter | Venezuela | Venezuelan generic brand with multiple strengths. |
Inmunolab (Ibuprofeno Inmunolab) | Argentina | Local brand, may be sold in different strengths and forms. |
La Santé | Colombia, Costa Rica, Dominican Republic, Ecuador, others in the region | Another regional generic; fairly common. |
Tips for Recognizing and Choosing Ibuprofen Brands
- Look for “Ibuprofeno / Ibuprofen” on the packaging in Spanish (or Portuguese in Brazil), that helps confirm the active ingredient.
- Check the dosage strength (e.g. 200 mg, 400 mg, 600 mg). OTC doses are usually up to 400 mg in many Latin American countries; higher doses may require prescription.
- Check the form (tablet, capsule, liquid) and whether there are added ingredients (like caffeine, or in the case of Maxigesic IV, combined with paracetamol).
- Buy from reputable pharmacies: even generic or local brands are safer when purchased in regulated pharmacies.
- Be aware of pricing and availability: Some brands might cost more because they are imported, or because they have extra features (e.g. “fast release”, coated tablets).
Safety Considerations When Taking Ibuprofen

While ibuprofen is one of the most effective and widely available over-the-counter medications for fever and pain relief, it should always be used responsibly to ensure safety and avoid side effects.
Proper dosage is essential, particularly in children, where the recommended amount depends on age and weight. Ibuprofen should always be taken with food or milk to minimize stomach irritation.
Overuse or long-term use of ibuprofen can have adverse effects on the stomach, kidneys, and heart, especially in individuals with preexisting conditions.
In a recent study by Bessone et al. published in Clinical Gastroenterology and Hepatology, ibuprofen was found to induce high rates of drug-induced liver injury in Latin America.
Key Takeaway
Although ibuprofen doesn’t cure infections, it’s essential for controlling fever and inflammation, key immune responses to viral illness.
By blocking prostaglandins and resetting the body’s temperature, ibuprofen lowers fever and pain, helping patients recover faster and rest comfortably.
Used correctly, ibuprofen is a safe, affordable, and accessible fever treatment in Latin America, trusted for relief during dengue, influenza, and other viral infections.
