Famciclovir review





Famciclovir is an antiviral drug used to treat different kinds of herpes virus infections such as herpes zoster or shingles (a rash that usually occurs in people who have already suffered from chickenpox). It is also prescribed to treat repeated and stubborn outbreaks of herpes virus fever blisters and cold sores. Famciclovir is also used to control returning herpes simplex infections of the mucuous membranes and the skin of people with HIV or human immunodeficiency virus.

Famciclovir belongs to a class of medications known as antivirals. It must be emphasized that Famciclovir does not cure herpes and may not be able to stop the contamination of the virus to other people. The primary aim of Famciclovir is to decrease and alleviate the symptoms of the disease such as burning and tingling sensations, pain, tenderness and itching. It also facilitates healing of the sores as well as prevents new sores from forming.

Famciclovir comes in a tablet form and and can be taken orally on a full or empty stomach. If taken to treat shingles, the tablet is usually taken every 8 hours for a week. If it is used to treat fever blisters and cold sores, Famciclovir is taken as one dose at the earliest manifestation of the symptoms. If Famciclovir is used to handle recurrent genital herpes outbreaks, it is taken twice a day for a year or so, depending on the doctor’s assessment and prescription.

It is highly encouraged for people to follow the doctor’s prescription so as to avoid any complications or problems during medication. If ever the symptoms cease or disappear before the prescribed range of medication ends, individuals should still continue with the medication even if they already feel well. It is not advisable to stop Famciclovir medication without consulting a doctor.

Before taking Famciclovir, you should inform your doctor about any drug-related allergies to prevent complications during medication. It is also advisable to mention other medications, special diets, vitamins, herbal medicines and supplements that you are taking (if any) so that your doctor can check if the medicines would clash with each other or not. If you plan to be pregnant, are pregnant or breastfeeding, you should tell your doctor because some medications may not be advisable to be taken in the aforementioned situations.

Doctors usually perform special laboratory tests such as blood sampling and urine exams to be certain whether a person can take Famciclovir or not.

Just like any other drug, Famciclovir also has its own set of side effects such as headache, painful menstrual periods (for women), nausea, itching, vomiting, diarrhea, rashes, tiredness and stomach pain. Some people who take Famciclovir may become dizzy, disoriented, confused and drowsy which would make them unfit to drive a car or operate any kind of machinery.

Contact a doctor or go to the hospital immediately if the symptoms are very severe and persistent. The most common telltale signs of experiencing severe side effects from Famciclovir are numbness, burning sensations, pain, tingling numbness of the limbs.
