Want Relief? Medications That Can Help Cold and Flu Symptoms

Cold and Flu Symptom Relief: Prescription Medications

Both Oseltamivir (Tamiflu) and Zanamivir (Relenza) are anti-viral medications used to treat Avian (H5N1), Swine (pH1N1) and seasonal flu (influenza A-H3N2 and B).  These are most effective if started within 48 hours of onset of flu or cold-like symptoms.  These medications may reduce symptoms or shorten the duration by 1 or 2 days, and prevent flu complications.

Healthy adults, including pregnant or breastfeeding individuals, can take Tamiflu 75mg 1 capsule orally twice daily for 5 days. There are special dosing required for individuals with renal impairment (based on renal clearance), children (based on weight) and critically-ill patients.  There is currently a shortage for the commercially prepared liquid formulation, but your pharmacist may be able to prepare a mixture especially for you.

Some common side effects of Tamiflu are upset stomach (nausea and vomiting) and dizziness.

The treatment dosing for adults and children over the age of 7, is 2 doses via Relenza inhaler twice daily for 5 days.  Relenza is well tolerated, but some common side effects are cough and throat irritation.  It is not recommended for individuals with lung conditions such as asthma or bronchitis.
