Rebetol inhibits the replication of new virions, selectively inhibits synthesis of viral RNA, it does not suppress synthesis of RNA in a normal cells. Rebetol is the most effective against: herpes simplex virus, virus of smallpox, influenza viruses A and B, paramyxovirus (parainfluenza, mumps, Newcastle disease), reovirus, oncogenic RNA viruses.

Precautions

Rebetol is may cause a significant risk of serious harm to developing infants and abnormalities in a man's sperm, be very attentive using contraception medications. At least two forms of birth control during treatment and for six months afterwards are required.



Contraindications

Rebetol is contraindicated in patients hypersensitive to the components of Rebetol, in pregnant and breastfeedign women, in patients with chronic heart failure, myocardial infarction, kidney or liver failure, severe anemia, decompensated cirrhosis, autoimmune diseases, incurable thyroid disease, severe depression with suicidal intentions, children and adolescents under 18. Cautiousness should be exercised in patients with decompensated diabetes mellitus, pulmonary embolism, heart failure, thyroid disease (including hyperthyroidism), impaired clotting, thrombophlebitis, myelosuppression, haemoglobinopathy (thalassemia, sickle cell anemia), depression, suicidality (also in history).



Possible side effect

The most serious adverse reaction to Rebetol is anemia. Other side effects include: blood disorders, fever, hair loss, depression, fatigue, headache, insomnia, irritability, nausea, shortness of breath, joint or muscle pain, weight loss. Notify your doctor immediately if you experience any serious manifestation of the side effects listed above.



Drug interaction

Concomitant use with other antiviral drugs such as zidovudine (Retrovir), zalcitabine (Hivid) or stavudine (Zerit), may cause lactic acidosis. Medications which contain Mg2+ É Al3+, and also simethicone decrease absorption of Retrovir. Retrovir suppresses effects of zidovudine. In the patients with HIV infection concomitant treatment with Retrovir, zidovudine and stavudine leads to HIV viremia (a condition where viruses get into the bloodstream and can affect the rest of the body) and requires change of treatment.



Missed dose

Never take a double dose of this medication. If it is almost time of the next dose just skip the missed portion and continue to take the medicine according to the schedule.



Overdose

If you suppose that took too much of this medication seek immediate medical attention. There is no information about adverse effects of Rebetol overdose.



Storage

Rebetol should be stored at room temperature between 2-8 C (36-46 F).

Antivirals

A virus is a microscopic biological parasite that can multiply inside the living cells of the host. Outside the host cells the viruses consists of virions that may range in different size and forms. Some of the virions are so small that their size does not exceed the size of ribosomes, while the viruses such as vaccinia virus that are much larger than the most of the bacteria. Each virions consists of capsid that has a protein origin. The capsid helps to protect the contents of the viruses, determines what type of the host cells can attach and affect. Some of the viruses also contain lipids and carbohydrates that are compounds of the host cells. The interior core consist of the genetic material(DNA and RNA chains).

Virals infection begins when the virion attaches to the specific receptors on the surface of the host cells. For example HIV viruses binds to the CCR5 located on the lymphocytes. Then the virus penetrates into the cells and begins to reproduce. The virus replicates the genome and produces new proteins that form new cores and capsids.

Currently there are known more than 2000 of different viruses that may cause a viral infection. The viruses are spread in different ways. Some viruses are spread by insects, usually blood-sucking insects. Other such as influenza are spread through the air from one person to another. There are viruses that are transmitted through the blood, by the faecal-oral route(norovirus) and during sexual intercourse(HIV).

The preparations that are used for the treatment of virals infections called antiviral agents. The most known of them are Zovirax(acyclovir) and Valrex(valacyclovir). These medicines fit into the viral DNA(genetic material) and block its replication. As a result the viruses are unable to replicate and infection goes away. Zovirax and Valtrex are effective against Herpes simplex type 1 and 2, Varicella zoster(Chickenpox).

The transmission of viruses can also be prevented through the vaccines that contains the weakened or dead virions. Vaccines help the organism to produce antibodies that neutralizes viruses. Unfortunately, there are not available vaccines for the all types of viruses. For example, the vaccine for the HIV viruses is still not found.

Some people think that viruses can also be treated by antibiotics. However, antibiotics are used only for the treatment of the infections caused by bacteria and are useless for the viral infections.
