Rimantadine Hydrochloride

What condition does Rimantadine Hydrochloride treat?

Rimantadine Hydrochloride is used to prevent or treat influenza A. This may help make your symptoms less severe to get better. Taking this medication if you have been or will be exposed to the flu may help it prevent from getting on you. Rimantadine Hydrochloride is a synthetic antiviral drug. This is supplied as tablets for oral use. The Food and Drug Administration (FDA) has approved this medication.

This is not a vaccine. It is important to get a flu shot once a year at the beginning of every flu season.

How does Rimantadine Hydrochloride work?

Rimantadine Hydrochloride works by preventing a viral protein called M2. It usually mediates the carrying of acid ions through the influenza virion shell. The acid ions facilitate the dissolution of the virion coat. Thereby it enables the release of the viral RNA into the cytoplasm of the infected cell. By blocking M2, this drug blocks viral and breaks the cycle of viral infection and replication.

This medicine acts during viral replication to inhibit the assembly of the influenza virus. Rimantadine-resistant strains of the influenza-A virus have been isolated. However, these strains do not appear to possess increased virulence relative to the Rimantadine-sensitive virus.

What is the recommended dosage for Rimantadine Hydrochloride?

Take this medication regularly to get the most benefit from it. Take it exactly as it is prescribed. Do not take it more often than the prescription.
