FAMCICLOVIR TAB

FAMCICLOVIR TAB: Famciclovir is an antiviral medication that is primarily used for the treatment of herpes infections, including genital herpes, cold sores (oral herpes), and shingles (herpes zoster). It belongs to a class of drugs called nucleoside analogues.

The mechanism of action of famciclovir involves the conversion of the drug into an active form called penciclovir. Penciclovir then works by inhibiting the replication of the herpes virus. It does this by blocking the action of an enzyme called DNA polymerase, which is essential for the replication of the virus.

The recommended dose of famciclovir depends on the specific condition being treated. For the treatment of genital herpes, the usual dose is 250 mg three times daily for 7 to 10 days. For the treatment of shingles, the typical dose is 500 mg every 8 hours for 7 days. For the treatment of cold sores, the usual dose is 1500 mg as a single dose.

Common side effects of famciclovir may include headache, nausea, diarrhea, dizziness, and tiredness. Less common but more serious side effects may include allergic reactions, including rash, itching, swelling, severe dizziness, and trouble breathing. It is important to seek medical attention immediately if any severe side effects occur.

It is worth noting that famciclovir is not a cure for herpes infections, but it can help to reduce the severity and duration of outbreaks. It is generally most effective when started early in the course of an outbreak. It is important to follow the prescribed dosage and complete the full course of treatment as directed by a healthcare professional.
