Actual product may differ in appearance from image shown.
Famciclovir (Famcimac) is a fast-acting antiviral medication used to treat infections caused by the herpes virus family, including genital herpes (HSV-2), cold sores (HSV-1), and shingles (herpes zoster). After ingestion, Famciclovir is converted into penciclovir, a potent compound that blocks viral DNA replication, helping stop the virus from multiplying and shortening the duration of outbreaks.
This medication is valued for its high oral bioavailability, rapid symptom relief, and long-lasting antiviral activity, making it suitable for both initial episodes and recurrent outbreaks. Famciclovir can also reduce pain, speed up skin healing, and lower the risk of transmission during active episodes.
Famcimac is a trusted generic formulation, manufactured under strict quality standards to provide an effective and affordable alternative to the original brand (Famvir). It is commonly prescribed for acute treatment, long-term suppression, and episodic therapy depending on patient needs.
When taken at the first sign of symptoms, Famciclovir helps control flare-ups more efficiently and supports faster recovery while maintaining excellent tolerability for most users.
Active ingredients:
Famciclovir (Famcimac), containing the active ingredient Famciclovir C₁₄H₁₉N₅O₄, provides fast and reliable antiviral protection by blocking viral DNA replication, reducing the severity and duration of herpes outbreaks, speeding lesion healing, lowering transmission risk, and offering effective relief for HSV-1, HSV-2, and shingles with strong clinical safety.
Indications:
- Genital Herpes (HSV-2) – Initial Episode: Famciclovir is prescribed for the first outbreak of genital herpes, which often causes severe pain, burning, fever, and painful sores. Treatment helps shorten the duration, reduce viral load, and speed up lesion healing;
- Genital Herpes (HSV-2) – Recurrent Episodes: Used at the first sign of tingling, itching, or redness to stop a flare-up from progressing. Famciclovir drastically reduces symptom severity and can prevent visible sores from forming;
- Genital Herpes Suppressive Therapy: For patients with frequent outbreaks, a daily low-dose regimen helps prevent recurrences, reduce symptom frequency, and decrease the risk of transmission to partners;
- Herpes Labialis (Cold Sores – HSV-1): Famciclovir treats cold sores appearing on the lips or around the mouth. Taking it early speeds healing and reduces discomfort, swelling, and blister duration;
- Shingles (Herpes Zoster): Famciclovir is a first-line treatment for shingles in adults. It reduces virus replication, decreases nerve pain, speeds skin healing, and lowers the chance of long-term nerve damage (postherpetic neuralgia);
- Recurrent Shingles in Immunocompromised Patients: In individuals with weakened immunity, Famciclovir helps control repeated herpes zoster outbreaks and prevents complications;
- Herpes Zoster Ophthalmicus (Shingles Affecting the Eye): Used to reduce the viral impact on the eye and prevent permanent damage such as vision loss. Must be taken promptly;
- Herpes Simplex Infections in Immunocompromised Patients: People with lowered immunity (HIV, cancer therapy, steroid use) may have severe or extended herpes infections. Famciclovir reduces flare intensity, accelerates healing, and prevents complications;
- Postherpetic Neuralgia Prevention: Given during acute shingles episodes to reduce the chance of developing chronic nerve pain afterward, especially in older adults;
- Oral HSV Outbreak Prevention Before Dental Procedures: Sometimes prescribed before dental or surgical interventions in people prone to herpes flare-ups to prevent activation of the virus due to stress or tissue irritation;
- Episodic Therapy for Stress-Induced HSV Outbreaks: Useful for patients whose herpes outbreaks are triggered by stress, illness, excessive sun exposure, or hormonal changes. Taken early, it prevents the outbreak from becoming severe;
- Chronic HSV Management in Patients with High Transmission Risk: Helps reduce the likelihood of spreading genital herpes to sexual partners when combined with safe practices.
- Genital Herpes (HSV-2) – Recurrent Episodes: Used at the first sign of tingling, itching, or redness to stop a flare-up from progressing. Famciclovir drastically reduces symptom severity and can prevent visible sores from forming;
- Genital Herpes Suppressive Therapy: For patients with frequent outbreaks, a daily low-dose regimen helps prevent recurrences, reduce symptom frequency, and decrease the risk of transmission to partners;
- Herpes Labialis (Cold Sores – HSV-1): Famciclovir treats cold sores appearing on the lips or around the mouth. Taking it early speeds healing and reduces discomfort, swelling, and blister duration;
- Shingles (Herpes Zoster): Famciclovir is a first-line treatment for shingles in adults. It reduces virus replication, decreases nerve pain, speeds skin healing, and lowers the chance of long-term nerve damage (postherpetic neuralgia);
- Recurrent Shingles in Immunocompromised Patients: In individuals with weakened immunity, Famciclovir helps control repeated herpes zoster outbreaks and prevents complications;

- Postherpetic Neuralgia Prevention: Given during acute shingles episodes to reduce the chance of developing chronic nerve pain afterward, especially in older adults;
- Oral HSV Outbreak Prevention Before Dental Procedures: Sometimes prescribed before dental or surgical interventions in people prone to herpes flare-ups to prevent activation of the virus due to stress or tissue irritation;
- Episodic Therapy for Stress-Induced HSV Outbreaks: Useful for patients whose herpes outbreaks are triggered by stress, illness, excessive sun exposure, or hormonal changes. Taken early, it prevents the outbreak from becoming severe;
- Chronic HSV Management in Patients with High Transmission Risk: Helps reduce the likelihood of spreading genital herpes to sexual partners when combined with safe practices.
Benefits:
- Fast antiviral action: Famciclovir is rapidly converted into penciclovir, which quickly blocks viral DNA replication. This allows symptoms to decrease within the first 24–48 hours when taken early in an outbreak;
- Highly effective for genital herpes (HSV-2): It reduces pain, burning, swelling, and the duration of lesions. Famciclovir also lowers virus shedding, making transmission less likely during active outbreaks;
- Strong relief for cold sores (HSV-1): Taking Famciclovir at the first sign of tingling or redness shortens recovery time and can prevent blisters from fully developing;
- First-line therapy for shingles (herpes zoster): Famciclovir reduces skin inflammation, speeds healing, decreases rash severity, and lowers the risk of long-lasting nerve pain (postherpetic neuralgia);
- Prevents future herpes outbreaks: When used as suppressive therapy, it reduces the frequency of recurrences by up to 70–80% in many patients;
- Helps reduce transmission risk: Daily low-dose treatment lowers viral shedding, which can help decrease the chance of spreading HSV to sexual partners;
- Effective in immunocompromised patients: Famciclovir works well for herpes infections in patients with weakened immunity (HIV, chemotherapy, steroid treatment), where outbreaks may otherwise be severe and prolonged;
- Convenient dosing regimen: Compared to some other antivirals, Famciclovir often requires fewer daily doses, making it easier for patients to follow the treatment plan;
- Strong safety profile: Most patients tolerate Famciclovir very well, with minimal side effects. It is considered one of the better-tolerated antiviral options;
- Reduces duration of pain and discomfort: Even after visible lesions disappear, herpes can cause nerve irritation. Famciclovir helps shorten both the acute symptoms and post-outbreak discomfort;
- Speeds up skin recovery: The medication helps skin lesions dry faster and heal with lower risk of secondary bacterial infection;
- Can be used for episodic, suppressive, or long-term therapy: It is flexible and suitable for one-time burst therapy, daily prevention, or long-term management depending on patient needs;
- Helps control stress-triggered outbreaks: Famciclovir is useful for people who experience flares due to stress, sun exposure, hormonal changes, or illness;
- Suitable for adult and elderly patients: Older adults especially benefit from faster recovery from shingles and reduced risk of neuralgia;
- Lower resistance risk compared to some older antivirals: Famciclovir has a strong resistance profile, making it reliable even in recurrent or persistent HSV infections;
