Recommended Treatments for Common Symptoms
1. Fever
Paracetamol (acetaminophen) 1,000 mg is the first-line treatment for fever in adults, with the combination of paracetamol 500 mg/ibuprofen 150 mg as an effective alternative, particularly for bacterial fever. 1
- For adults presenting with fever, paracetamol 1,000 mg achieves temperature reduction of at least 1 degree and 1-point reduction in associated symptoms within 1 hour in 37% of patients 1
- The paracetamol/ibuprofen combination (500/150 mg) is more effective than paracetamol alone for bacterial fever at 1 hour (48.6% vs 33.6% response rate), though both achieve similar efficacy by 2 hours 1
- NSAIDs provide significant benefit for fever-associated symptoms including headache, ear pain, and muscle/joint pain 2
2. Cold and Cough
For acute cough with common cold, use first-generation antihistamine/decongestant combinations (brompheniramine with sustained-release pseudoephedrine) or naproxen; avoid newer nonsedating antihistamines as they are ineffective. 3
Adults:
- First-generation antihistamine/decongestant preparations provide substantial benefit for cough, post-nasal drip, and throat clearing 3
- Naproxen decreases cough associated with common cold 3
- Zinc, nasal decongestants with or without antihistamines, and ipratropium for cough have proven effectiveness 4
- Newer generation nonsedating antihistamines are ineffective and should not be used 3
Children:
- Safe and effective treatments include acetylcysteine, honey (for children ≥1 year), nasal saline irrigation, intranasal ipratropium, and topical ointment containing camphor, menthol, and eucalyptus oils 4
- Over-the-counter cold medications should NOT be used in children younger than 4 years 4
Common pitfall: Do not diagnose bacterial sinusitis during the first week of cold symptoms, as 87% of patients show sinus abnormalities on imaging that resolve without antibiotics 3
3. Constipation
No specific evidence provided in the literature for this symptom. Based on general medical practice, use osmotic laxatives (polyethylene glycol) as first-line, followed by stimulant laxatives if needed, with attention to hydration and dietary fiber.
4. Diarrhea
For acute diarrhea, rehydration is the primary treatment; empiric antibiotics are NOT recommended for most immunocompetent patients with bloody diarrhea while awaiting test results. 5
When to use empiric antibiotics:
- Infants <3 months with suspected bacterial etiology 5
- Ill immunocompetent patients with documented fever, abdominal pain, bloody diarrhea, and bacillary dysentery (frequent scant bloody stools, fever, cramps, tenesmus) presumed to be Shigella 5
- Recent international travelers with temperature ≥38.5°C and/or signs of sepsis 5
- Immunocompromised patients with severe illness and bloody diarrhea 5
Antibiotic choices:
- Adults: fluoroquinolone (ciprofloxacin) or azithromycin, depending on local susceptibility patterns and travel history 5
- Children: third-generation cephalosporin for infants <3 months or those with neurologic involvement; azithromycin based on local patterns 5
Critical caveat: AVOID antimicrobial therapy for STEC O157 and other STEC producing Shiga toxin 2, as antibiotics may worsen outcomes 5
- For persistent diarrhea (≥14 days), consider noninfectious conditions including lactose intolerance, inflammatory bowel disease, and irritable bowel syndrome 5
- Preventing dehydration or providing appropriate rehydration is the primary supportive treatment 6
5. Headache
NSAIDs provide significant analgesic benefit for headache associated with common cold and fever. 2
- NSAIDs produce significant benefits for headache in the context of common cold 2
- Over-the-counter analgesics have proven effectiveness for cold-associated headache 4
- Paracetamol 1,000 mg or paracetamol/ibuprofen combination effectively reduces headache associated with fever 1
6. Stomach Pain (Abdominal Pain)
For abdominal pain with diarrhea, focus on rehydration and identifying the underlying cause; reassess fluid/electrolyte balance and nutritional status if symptoms persist. 5
- Abdominal pain with bloody diarrhea and fever may indicate Shigella infection requiring empiric antibiotics 5
- For persistent symptoms, reassessment of fluid and electrolyte balance, nutritional status, and antimicrobial therapy duration is recommended 5
- Consider noninfectious conditions (IBD, IBS) for symptoms lasting ≥14 days 5
Important note: Abdominal pain is a common gastrointestinal symptom in COVID-19 patients, occurring in 3.8% of hospitalized patients 7
7. Stomach Burn (Heartburn)
No specific evidence provided in the literature for acute heartburn treatment. Based on general medical practice, use proton pump inhibitors (omeprazole 20-40 mg daily) or H2-receptor antagonists (famotidine 20 mg twice daily) for symptomatic relief, with lifestyle modifications including avoiding trigger foods and elevating the head of the bed.
Context note: Heartburn is a recognized symptom in post-COVID gastrointestinal dysfunction and may persist for months after acute infection 8, 9
