Effectiveness
How Relenza Affects PatientsZanamivir is a medication used to treat the flu in adults and children over the age of 7 who have been suffering from symptoms for no more than 2 days. It works by blocking an enzyme (neuraminidase) that the virus needs to spread in the body. Rare side effects have been linked to zanamivir's ability to inhibit certain enzymes (NEU3 and NEU2) in the body.
How Relenza works in the bodyZanamivir works by blocking the influenza virus' ability to escape infected cells and spread to other cells. It does this by inhibiting the neuraminidase protein, which stops the virus from being able to leave the cell.

5Patient Review
4/25/2009 I felt incredibly nauseous and had severe abdominal pain for days after taking this medicine. It was an absolutely terrible experience and I would not wish it on anyone.

10/8/2015 Relenza has been a game-changer for me when it comes to flu symptoms. I used to get pneumonia frequently, but since taking this medication, I haven't had any problems.

2/26/2009 My son took this around 8:30 p.m. on Thursday and felt much better by the next day, enough to go back to school on Monday.

7/2/2009 The medication helped with the flu, but not my runny nose. Additionally, it left me feeling very dried-out and I lost my sense of taste. I had diarrhea and some abdominal cramping. Overall, not a great experience.
3.3Patient Review
11/1/2009 I started taking Relenza when my husband came down with the flu and I began experiencing similar symptoms. The medication has helped, though I have experienced some earache and stomach cramps as side effects. My husband, who started taking the drug a little later than me, hasn't fared as well; his symptoms have improved but he is very fatigued.
3Patient Review
10/12/2009 I began taking this medication the day after I started feeling ill. Unfortunately, the side effects were worse than the flu itself. Let's hope I never have to take it again.
2.7Patient Review
5/2/2009 Relenza did help to lower my fever and get rid of my aches, however the side effects have been really tough to deal with. Headaches and diarrhea have gotten worse after each dose, and I've been feeling pretty dizzy too. If you decide to try this medication, make sure you're prepared with lots of Pedialyte and Excedrin!
2.7Patient Review
7/24/2009 I'm a 20 year old girl who is 9 weeks pregnant. I've been taking Relenza for two days and, while it has taken away my aches and pains, the side effects have been really terrible. I've had headaches, earaches, toothaches, and now mouth blisters. It seems like I'm in more pain now than before.
2.7Patient Review
11/13/2009 On the second day of using Relenza, I had an extreme outbreak of cold sores on my face. This was so bad that I had to go see a doctor. It was extremely painful and it's something I never want to experience again.
1.7Patient Review
10/30/2009 I unfortunately began taking this medication after I was diagnosed with swine flu. In retrospect, the side effects are worse than the actual virus. I would advise others to use caution before taking this drug as it made my condition more complicated and uncomfortable.
1.3Patient Review
7/30/2009 I'm nine weeks pregnant and was offered this inhaler. I have been using it for a day, but my symptoms have actually increased. I now have a bad cough, tight chest, runny nose, loss of appetite, sickness, and fever.
1Patient Review
7/16/2009 My daughter experienced some serious heart pains and headaches after only a few doses of this medication. I'm glad we stopped taking it when we did, as I would hate to think of what could have happened if we hadn't. We're going to get a second opinion from another medical professional just to be safe.
