Application of the active substance oseltamivir
Oseltamivir is used for the prevention and treatment of the flu. For the treatment of a flu infection, the drug must be taken within two days of the onset of the first symptoms. To prevent infection, Oseltamivir should be used as soon as possible after contact with an infected person.
Oseltamivir should be used in accordance with age and in children by weight. Only in the case of a global outbreak of influenza, the drug may be given to prevent infraction to infants under one year. For premature babies, however, there are no dosage recommendations.
The active substance can not cure the flu. It merely alleviates the symptoms and shortens the duration of the illness. This also reduces the risk of serious sequelae such as pneumonia. Oseltamivir can not replace a flu vaccine.
The use of oseltamivir should be strictly limited to use in the event of a flu epidemic and should be monitored by a physician.

Effect of Oseltamivir
Oseltamivir is a neuraminidase inhibitor and therefore one of the virus-inhibiting agents.
The flu virus invades human cells to multiply. The viruses newly formed in the cell have to leave them in order to infect new cells and thus spread. To leave the cell, a link between the virus and the cell must be cut using the enzyme neuraminidase. Oseltamivir prevents this process by blocking the enzyme. So the virus can not infect new cells. For the human immune system, the immobile viruses are also easier to defeat.

Actual situation: start of therapy after the onset of the first symptoms after 24 hours. At the moment Tamiflu has been taken for 3.5 days and another 1.5 days are planned. At the moment clear improvement of the disease. On the first day simultaneous administration of paracetamol and Mucosolvan (self-produced). No medication other than Tamiflu from the second day. Side effect: change in taste perception, more specifically the sense of smell. The taste qualities sweet, sour, etc. are taken care of by me without disturbance. When taking especially dairy products (except cheese) and passion fruit juice it comes to an unpleasant aftertaste, which is currently best comparable to the smell of natural gas. This can also be produced without food, but not as strong as in connection with the products mentioned, by conscious sniffing . Coffee, pumpkin soup, baked fish, boiled celery and potatoes have no negative influence. Apples promote the occurrence only very slightly.

Tamiflu for Fever
Had to fight with the virus H1N1. A high rise in fever, I did not come to 39 ° C fever, despite taking acetaminophen, which has always lowered my fever when I was sick. Even the calf wrap was not able to significantly lower my fever. Paracetamol did not help with my body aches either. My doctor then prescribed me Tamiflu (flu remedy), 2 pieces daily. Drug immediately struck, where paracetamol has only inhibited the fever rise, so I woke up with Tamiflu the next morning with a temperature of 37.4 ° C, and the pain was gone (especially the terrible headache). At the first intake of the drug, I had a slight abdominal pain for a few minutes, but continued treatment, these disappeared.

Our son had high fever flu and all side effects described with flu. Since I travel a lot for work, I took Tamiflu prophylactically. The first two days 2 x 1, then only once a day 1x. On the first two days of use after about 1/2 hour moderate abdominal pain, which lasted about 2 hours. From the third day on, no abdominal pain. Flatulence all the time and also flavor changes I had. But after completing the taking but completely subsided. Chair change, I have also found. Skin reddening occurred on the decolt and neck during the period of ingestion. Also, the skin discolored on contact with warm water (red hands, red feet) and I had the feeling of a slight temperature insensitivity. Otherwise, everything was bearable, no after-effects and the flu I did not get until today.

Unfortunately, I can not recommend Tamiflu. I am suffering from mild endogenous bronchial asthma, and the medication completely blocked my airways after about 3 hours. As I subsequently learned from my pulmonary doctor, this is called a bronchospasm. For me, this was a borderline situation that I was able to solve myself with Salbutamol Spray. In addition, after a very short time, it has become very bad for me. Without nausea, but just bad. Asthmatics should be very careful with this drug, even the second flu drug Relenza is not suitable for asthmatics. So I can not make any judgment regarding the actual effect of Tamiflu. I only know that I can not take it again.
