Comprehensive Guide to Medicines for Viral Fever

Health and Fitness

Viral fever, a prevalent condition caused by viral infections, results in elevated body temperature and a variety of other symptoms. Since antibiotics are ineffective against viruses, it’s crucial to understand the appropriate medicines to manage viral fever. This guide delves into the various medications, their functions, and the appropriate usage for treating viral fever.

Understanding Viral Fever

Viral fever occurs due to infections caused by viruses, which are tiny infectious agents that invade host cells to replicate. These infections can affect different parts of the body, including the respiratory system, gastrointestinal tract, and other organs. Common viral infections that cause fever include influenza, the common cold, dengue, and COVID-19. Treatment often involves rest, hydration, and medicine for viral fever to alleviate symptoms and help the body fight off the infection.

  • NSAIDs (Ibuprofen, Naproxen): Provide pain relief along with their fever-reducing and anti-inflammatory properties.

Dosage and Administration:

  • Follow the same guidelines as for antipyretics, as these medications often overlap in their use.

Side Effects:

  • Similar to those listed under antipyretics, with additional caution for people with certain health conditions.

3. Antiviral Medications

Function: Antiviral drugs are designed to treat specific viral infections by inhibiting the replication of viruses.

Common Antiviral Medications:

  • Oseltamivir (Tamiflu): Used to treat influenza A and B. It is most effective when taken within 48 hours of symptom onset.
  • Remdesivir: Initially developed for Ebola, it has been repurposed to treat COVID-19 in hospitalized patients.

Dosage and Administration:

  • Oseltamivir: Typically, the dose is 75 mg twice daily for 5 days for adults. Pediatric dosing is based on weight.
  • Remdesivir: Administered intravenously in a hospital setting, with dosing and duration depending on the severity of the infection.

Side Effects:

  • Oseltamivir: Nausea, vomiting, and possible psychiatric effects in rare cases.
  • Remdesivir: Nausea, elevated liver enzymes, and potential kidney issues.

4. Decongestants and Antihistamines

Function: These medications help alleviate symptoms such as nasal congestion and runny nose associated with viral infections.

Common Decongestants and Antihistamines:

  • Pseudoephedrine (Sudafed): A decongestant that reduces nasal congestion by constricting blood vessels in the nasal passages.
  • Diphenhydramine (Benadryl): An antihistamine that relieves symptoms of allergies and colds, such as runny nose and sneezing.

Dosage and Administration:

  • Pseudoephedrine: The adult dose is 60 mg every 4-6 hours, not exceeding 240 mg per day. It is not recommended for children under 4 years.
  • Diphenhydramine: The adult dose is 25-50 mg every 4-6 hours, not exceeding 300 mg per day. Pediatric dosing is available but should be used with caution.

Side Effects:

  • Pseudoephedrine: Insomnia, nervousness, and increased blood pressure.
  • Diphenhydramine: Drowsiness, dry mouth, and potential for confusion in the elderly.

5. Cough Suppressants and Expectorants

Function: These medications help manage cough associated with viral infections.

Common Cough Suppressants and Expectorants:

  • Dextromethorphan (Robitussin, Delsym): A cough suppressant that reduces the urge to cough.
  • Guaifenesin (Mucinex): An expectorant that helps thin and loosen mucus, making it easier to cough up.

Dosage and Administration:

  • Dextromethorphan: The adult dose is 10-20 mg every 4 hours, not exceeding 120 mg per day. Pediatric dosing is available.
  • Guaifenesin: The adult dose is 200-400 mg every 4 hours, not exceeding 2400 mg per day. Pediatric formulations are also available.

Side Effects:

  • Dextromethorphan: Dizziness, drowsiness, and nausea.
