The flu (also called influenza) is a disease known to all, which begins to manifest itself in the respiratory system of the individual who has it, before being reflected through almost the entire body. It is therefore a very disabling disease that must be taken seriously through, for example, the administration of Tamiflu which is a popular treatment against influenza
During its acute phase, the flu can completely immobilize the sick person. However, in the vast majority of cases, flu sufferers recover perfectly within 3 days to 1 week. If the remission rate is so good, it is because the drugs developed by specialized pharmaceutical laboratories are particularly effective.
The flu: definition, symptoms and treatments
She returns every year towards the end of December, seasonal flu is unforgivable! This is the direct cause of more than 250,000 deaths per year around the world.
It is a seasonal respiratory infection , of viral and infectious origin. The viruses responsible evolve every year causing an annual epidemic which generally sets in for a minimum of nine weeks.
Symptoms of the flu
Although the symptoms may differ from one individual to another, in general seasonal flu is characterized by the sudden onset of a fever which can be very high.
This fever is accompanied by general fatigue, but also joint and muscle pain. On some individuals, we may observe a runny nose, sore throat giving off a dry cough, as well as headaches of varying intensity.
The seasonal flu is extremely contagious, which explains the high rate of sickness each year around the world. The influenza viruses that are responsible for it pass from person to person, especially through nasal secretions caused by sneezing or a simple cough.
The flu is most often transmitted by touching an infected object, it can be a doorknob, a pencil, a phone or any other object that has been in contact with a person who is asleep and already sick. It is also sufficient to touch a sensitive area (eyes, nose, lips, etc.) of an infected individual to in turn catch the virus. It is for these reasons that the flu is most often encountered in offices, as well as in schools. Indeed, the population is large there and individuals tend to use the same equipment.
Severity and duration of an influenza epidemic
The flu is not a trivial disease and it should therefore be taken seriously, it is an infection capable of spreading worldwide and no individual is therefore immune (even the vaccine is not an efficiency rate of 100%, far from it even because it would be more around 60%).
The influenza virus causes severe symptoms , which can lead to death, mainly if it affects debilitated or at-risk individuals. The influenza infection sets in for a long stay in the patient’s body, which first begins with an incubation period (which can range from 24 to 48 hours), then the first symptoms appear. You should know that the carrier of the virus remains contagious for an average of 6 days. If one relies on world statistics, one can affirm that the influenza virus in a patient not being considered as “at risk”, lasts on average 2 weeks.
How can you prevent the flu?
Unfortunately, it is quite difficult to escape it, but by preventing it, we reduce the risk of being contaminated. First of all, take advantage of the vaccine that is available at the start of the flu period. Those who are in direct contact with infected patients, especially medical personnel, but also vulnerable people must be vaccinated to significantly reduce the risk of infection.
Some homeopathic treatments such as Oscillococcinum® and Influenzinum 9 CH help prevent influenza. It is necessary to proceed to a cure before each period or influenza infections spread.
Of course, cleanliness when exposing yourself to an infected person is very important, so you have to wash your hands more frequently than usual, using a hydroalcoholic solution and soap for this.
Preventing the flu by eating a healthy diet is also possible! Know for example that carrots strengthen the immune system as well as any other fruit that is rich in vitamins.
What is Tamiflu?
You may have heard of this treatment before if you have ever had the flu. It is indeed a very popular drug (because it is extremely effective) in the treatment of influenza infections . In this sheet, you will find everything you need to know about Tamiflu to take this treatment while avoiding all risks.
Tamiflu is prescribed by a doctor and is a drug designed to prevent Influenza, which is the virus that causes influenza. Its active ingredient is Oseltamivir and its production is based on shikimic acids, which act as neuraminidase inhibitors (this enzyme attacking the walls of contaminating cells). Tamiflu is also used to treat symptoms triggered by the A H1N1 flu. Tamiflu is a drug belonging to the family of neuraminidase inhibitors, the role of which is to protect the body to prevent influenza infection. This drug has been approved and authorized by the US agency FDA as well as by European health authorities since 2002.
How does this medicine work?
Once ingested, 75% of the drug is transformed in the body by enzymes into the oseltamivir carboxylase, which is the active ingredient in Tamiflu. This molecule remains intact in the body, which allows its resistance to the influenza virus , preventing the spread of an epidemic.
To better understand, the active principle of Tamiflu (oseltamivir) inhibits certain enzymes which remain on the surface, they are called neuraminidases. Once inhibited, the spread of infection is neutralized.
In what form is it presented?
There are 3 strengths in capsule form to be swallowed with a liquid drink
– Tamiflu 30 mg
– Tamiflu 45 mg
– Tamiflu 75 mg
– Oral suspension (6 mg / ml): This version comes in a small bottle containing a white powder, with a tutti frutti flavor, intended for the reconstitution of diseased cells. Most used for children and other individuals who have problems swallowing conventional capsules.
How to use Tamiflu?
The use of Tamiflu is not to be taken lightly, to avoid all risks, you should always refer to the indications prescribed by your doctor, however, this sheet can serve you general information on this popular treatment. Tamiflu can be taken at any time of the day, both during the meal and at any other time. This involves swallowing capsules with the help of a glass of water if the sick individual is an adult or a child of at least 13 years old.
Children under 13 and people who have trouble swallowing the capsules correctly (risk of suffocation), have the option of opting for the oral suspension, dosed at 6 mg / ml.
What dosages should be administered?
Preventive dosage, when the individual has come into contact with a sick person:
After having been in direct contact with an infected person, it is advisable to start treatment without too much delay, preferably without exceeding 48 hours after the contact considered “at risk”.
For an adult (and children over 40kg), the usually prescribed dose is 75 mg taken once a day. Once treatment has started, it should be extended over a period of 10 days.
For children over one year of age, whose weight is 10 to 15 kg , a dose of 5 ml (oral suspension) should be taken once a day, with a meal. The duration of treatment should be spread over 10 days.
For children over one year of age, whose weight is 16 to 23 kg , a dose of 7.5 ml (oral suspension) should be taken once a day, with a meal. The duration of treatment should be spread over 10 days.
For children over one year of age, whose weight is 24 to 40 kg , a dose of 10 ml (oral suspension) should be taken once a day, with a meal. The duration of treatment should be spread over 10 days.
Dosage when the individual is already infected with the virus:
When the weight of the sick person is between:
- 10 and 15 kg, 5 ml of oral suspension are administered morning and evening for 5 consecutive days.
- 16 and 23 kg, 7.5 ml of oral suspension are administered morning and evening, for 5 consecutive days.
- 24 and 40 kg, 10 ml of oral suspension is administered morning and evening, for 5 consecutive days.
- For children under 1 year old, 0.2 to 0.3 mg per kg is administered twice (morning and evening). The correct dosage is done with a 0.1 ml graduated syringe that must be obtained from a pharmacy
- For adults and children over 40kg, it is to take 75mg of Tamiflu (morning and evening), also for 5 days.
Preventive dosage, when it is proven that the epidemic has spread:
Adults will take a daily dose of 75 mg for the duration of the epidemic, which can last up to 6 weeks.
For special cases (allergy to components, renal failure, etc.) the doses will be adjusted by the doctor prescribing Tamiflu.
Side effects of Tamiflu
Some people, even if these remain relatively isolated cases, have felt more or less embarrassing concerns when taking Tamiflu. Do not hesitate, you too, to report to your doctor any effects that you consider undesirable or unforeseen.
Like most drugs, Tamiflu therefore also generates side effects, more or less serious. The side effects listed here are not experienced by everyone, however some patients have complained and reported the items noted below:
- Heartburn and abdominal pain
- Mild to moderate diarrhea and nausea. In some rarer cases, vomiting is noted.
- Headaches, dizziness, great fatigue as well as sleep disturbances (this is to differentiate these side effects, with the classic symptoms of the flu).
Neurologically, other adverse effects have been reported, including:
- A slight agitation.
- Abnormal behavior.
- A confusion.
These side effects at the neurological level are mainly seen in children. Today it is difficult to say whether they come from the influenza virus itself, or from the active principle of Tamiflu.
It is also important to remain alert and to report any suspicious reactions in your body, when starting this treatment. Here are the signs that may lead the patient to stop treatment and seek urgent medical attention:
- If, while taking this medicine, you notice an allergic reaction or an unexpected rash.
- Yellowing of the skin or around the whites of the eyes.
- Loss of appetite.
- Severe abdominal pain.
- Brownish urine as well as pale stools.
- Extreme weakness or fatigue.
Again, although side effects have been noted in some patients, these remain mostly very isolated cases . These side effects go away within 48 hours of starting treatment, and the vast majority of people continue their Tamiflu-based antiviral treatment.
Precautions for use
It is important when you are prescribed Tamiflu treatment that you tell your doctor about any other illnesses, taking any medications, allergies, heart problems, severe breathing difficulties, immunosuppression (weakened immune system), kidney problems. For women, it is absolutely necessary to report an ongoing pregnancy, so as not to risk degrading the health of the fetus.
Indeed, all this can disturb the effects of the drug and it will then be necessary to adjust the doses, and carry out close medical supervision. It is equally important to report alcoholism or any other dependence on drugs, or substances considered harmful to health.
It is not excluded that a drug interaction takes place between the active ingredients of Tamiflu and other drugs. It is therefore necessary to pay attention and report to a doctor all the medicines you are taking before starting this treatment.
Indeed, here is a (non-exhaustive) list of drugs and active ingredients that can interact negatively with Tamiflu:
- The flu shot taken as a spray.
- Abnormal renal elimination leading to the intake of: chlorpromamide, methotrexate, phenylbutazone.
If, in fact, you are taking a medicine containing one of the agents mentioned, your doctor will have to change the doses, or indicate that you stop taking other medicines. They may also make changes to the way you take the medicine, depending on the case. Finally, in some cases the doctor will decide not to change anything, but will monitor them closely for the duration of treatment with Tamiflu.
Tamiflu is not an alternative to the flu vaccine, it is essential to continue to be vaccinated, each year, before the supposed period of the epidemic.
Tamiflu treatment should only be used when a healthcare professional diagnoses the circulation of the virus in the individual’s metabolism. In some cases, it can be used as a preventive treatment, such as when an individual at risk has been in direct contact with a sick person.
On the other hand, be aware that the doctor may need to prescribe Tamiflu for other health problems unrelated to the flu. However, no scientific study has yet proven the effectiveness of this treatment, apart from its positive effects on influenza infections.
