Famvir review





Famvir, which is generically prescribed as famciclovir, is commonly used to treat viral infections of the skin such as herpes, genital herpes, chicken pox, cold sores, and shingles. Famvir is a member of the family of drugs known as antiviral medications.

Famvir is not appropriate for everyone. A thorough medical history should be assessed prior to prescribing this medication. Patients with a medical history which includes, severe skin sensitivities, kidney disease, skin allergies, glucose-galactose malabsorption, galactose intolerance, or severe lactase deficiency may not be able to take Famvir or may require careful monitoring while undergoing drug therapy with this medication, depending on the condition and the severity of the condition.

The American Food and Drug Administration rated Famvir as a pregnancy risk category B. Famvir is not expected to cause harm or birth defects in unborn babies. It has yet to be determined whether or not Famvir passes through the mother’s breast milk and affects a nursing baby. The prescribing physician should discuss whether the benefits outweigh the risks prior to prescribing this medication to a woman who is pregnant or is likely to become pregnant. The prescribing physician should avoid prescribing this medication to women who are nursing.

There is a risk of side effects associated with Famvir, some of which are severe. If a patient is experiencing a serious side effect or an allergic reaction they should seek immediate emergency medical attention. An allergic reaction will present with symptoms which include facial swelling, such as swelling of the lips, mouth, tongue, or throat, hives, and difficulty breathing. Other serious side effects which require immediate emergency medical attention include symptoms such as two or more migraines within the first several days of treatment, dehydration due to vomiting or diarrhea, or a severe skin rash.

Other less serious side effects typically do not require emergency medical care but should be reported to the prescribing physician. Patients should be encouraged to report all side effects. Less serious side effects include symptoms such as headaches, nausea, vomiting, diarrhea, mild skin rash, itching, confusion, stomach pain, dizziness, or sleepiness. Less serious side effects can often be reduced to a tolerable level by reducing the dosage of Famvir.

Famvir should be taken exactly as it has been prescribed by the physician. If the patient misses a dose, the dose should be taken as soon as it is remembered. However, if it is almost time for the next scheduled dose, the missed dose should be skipped to avoid the potential for an overdose. The patient should never take a double dose of this medication. If an overdose is suspected, the patient should seek immediate emergency medical attention. An overdose may present with symptoms that include stomach problems, vomiting, diarrhea, confusion, agitation, sweating, mild tremors, or severe headaches. Some patients may not experience symptoms at all but should still be seen in the nearest emergency care facility.

There is a risk of drug interactions associated with Famvir. A thorough medical history should be understood prior to prescribing this medication. Patients should be urged to inquire with the prescribing physician before taking any new medications, including over the counter medications and herbal remedies. Medications that have a known interaction with Famvir include probenecid and additional oral antiviral medication. Antibiotics should not be taken in conjunction with antiviral medications.
