Antiviral Drugs And Their Purpose

Google+ Pinterest LinkedIn Tumblr +

Altogether, there are four antiviral flu drugs. I will go over each one of these, and talk a bit about some of the side effects.

One of the antiviral drugs in fighting influenza A or B is Relenza. This drug is for use in treating both children five years and older and adults. For Relenza to work effectively, it must be taken very shortly after the onset of these flu types and not more than 2 days later. This medication may also be given to prevent these flu types from happening to begin with. The drug will actually help neuraminidase, a type of enzyme , to produce healthier cells from cells that carry a virus. That way, the virus has a good chance of going away. Relenza is also a drug that is to be inhaled. It comes in 5 milligrams, and usually is inhaled up to twice daily.

Relenza does have a few side effects you should be aware of, and that is possible allergic reactions, and some troubles in breathing.

Tamiflu is another antiviral drug that can be given for influenza in anyone that is at least 12 months old and older. It can also be used to prevent influenza as well as to treat it. The same rule applies to this drug as it should be taken not any longer than 2 days after the virus has started. It works in the same way that Relenza does, by helping neuraminidase to stimulate the healthier cells in the body, and fight off the bad ones. The therapy for this influenza drug is 10 days.

Tamiflu comes in capsule form, or suspension.Most doctors will prescribe it for the person affected two times a day for ten days.

Tamiflu does have more possible side effects than Relenza. It can cause, (1) vertigo, (2) dermatitis of the skin, (3) lymph nodes that swell, (4) conjuctivitis, (5) eardrum problems, (6) allergic reactions, (7) rashes, (8) diarrhea, and (9) a headache. If you are taking Tamiflu, and these symptoms are bothersome, you should call your doctor and report it.

Another antiviral drug known as Amantadine also works against viruses in the body by putting a stop to the H1N1 virus. This medication comes in capsule or liquid suspension form.

One of the things that this drug does that the other antivirals don’t, is that it treats respiratory problems and infections due to the Swine Flu.

Like any other drug, this medicine can have several side effects with it. These are things like, (1) lightheaded feelings, (2) fainting spells, (3) vision is blurry, and (4) insomnia. There is also a possibility of more serious side effects such as, (1) trouble breathing, (2) rash, (3) problems urinating, and (4) body swelling. If these are some of the side effects you have from using Amantadine, contact your doctor immediately.

The last drug I’d like to mention is Flumadine. Flumadine works against the influenza A type viruses as does these other medications I have talked about. The drug comes both in a liquid suspension and also tablets. Ad in all cases, the sooner after your symptoms in beginning this drug, the better. It is best not to wait anymore than 2 days, (48) hours before getting this drug.

One of the big side effects of Flumadine is having many gastrointestinal symptoms with it. Also, people that have any kidney disease, liver disease, or renal impairments shouldn’t take this medication.

So the whole idea here with any of these medications, is to see your doctor soon at any sign of H1N1, instead of waiting. It is far better to be safe than sorry!
