Dengue cases increase every year during the monsoon season, and with every outbreak, I see the same questions from patients and their families. "Is there a medicine that kills the dengue virus?" "Should we panic if platelets start falling?" "When should we go to the hospital?" Read Full Story The biggest misconception is that dengue has a specific cure. The truth is that there is no targeted antiviral medicine available for dengue. Treatment is entirely supportive, which means our goal is to help the body recover safely while preventing dangerous complications. The good news is that most dengue patients recover completely with proper medical care. The key is recognising warning signs early, staying well hydrated, and avoiding common mistakes that can make the illness worse. In my experience, timely treatment and close monitoring can make all the difference between a smooth recovery and a medical emergency. Here are the most important things everyone should know about dengue treatment. 1. THE MOST DANGEROUS PHASE OFTEN STARTS WHEN THE FEVER COMES DOWN Many people believe they are getting better once the fever disappears. Unfortunately, this is often when dengue enters its most critical stage.

Around the third to fifth day of illness, especially when the fever starts settling, patients need careful monitoring. This is the period when complications such as plasma leakage, bleeding, or shock may develop. That is why I recommend regular clinical evaluations during this phase. Doctors usually monitor platelet counts, hematocrit levels, blood pressure, pulse rate, and overall clinical condition. If the patient remains stable and has no warning signs, recovery at home is often possible, provided the family understands when immediate medical attention is needed. 2. FLUIDS ARE THE MOST IMPORTANT TREATMENT Since no medicine directly kills the dengue virus, proper hydration becomes one of the most effective treatments. Patients with mild dengue should drink plenty of fluids, including water and oral rehydration solutions, to prevent dehydration. However, if warning signs appear or the patient is unable to drink enough because of vomiting or weakness, intravenous fluids become necessary. Fluids such as normal saline or Ringer's lactate are commonly used in hospitals. It is equally important not to give excessive fluids. Too much intravenous fluid can lead to complications such as fluid accumulation in the lungs, making breathing difficult. Doctors carefully calculate the amount of fluid required and monitor urine output, blood pressure, and other vital signs throughout treatment. In most patients, intravenous fluids are only needed during the critical 24 to 48-hour period.
