FAQs Of Vianca Tablet

Q1. Does Vianca cure HIV?
No — Vianca helps control HIV infection, reduce viral load, and preserve immune function, but it does not cure HIV or AIDS. 

Q2. What if I miss a dose?
Take the missed dose as soon as you remember unless it's nearly time for the next dose. Do not double the dose. Then continue at the usual time. 

Q3. Can I stop taking Vianca once I feel better?
No — stopping therapy can cause viral resurgence and drug resistance. Always follow your doctor’s advice. 

Q4. Can Vianca be used in pregnancy?
Use only if clearly needed and after doctor consultation. Efavirenz may pose risk in pregnancy; immunological status and other factors will be assessed. 

Q5. Will I still be infectious to others?
Even with Vianca and suppressed viral load, there's still risk of HIV transmission. Use barrier protection and follow medical advice.

Drug Interactions Of Vianca Tablet

• 
  1. Other Antiretroviral Drugs: Avoid combining with other medicines containing Efavirenz, Lamivudine, or Tenofovir, as it may cause overdose or toxicity.Do not take with Adefovir or Didanosine, since both increase the risk of kidney damage and lactic acidosis.
• 2. Antifungal & Antibiotic Medicines: Rifampicin, Rifabutin, Itraconazole, and Clarithromycin may reduce the blood levels of Efavirenz, making Vianca less effective. Doctors may adjust doses or suggest alternatives if such drugs are needed together.
• 3. Anticonvulsants (Seizure Medicines): Phenytoin, Carbamazepine, Phenobarbital can lower Efavirenz levels in blood, decreasing its antiviral activity.
• Dose monitoring may be necessary when used together.
• 4. Antidepressants / Sedatives / Antipsychotics: Taking benzodiazepines (e.g., Diazepam, Lorazepam) or antidepressants (e.g., Sertraline, Paroxetine) with Efavirenz can increase dizziness, drowsiness, or confusion.
• Efavirenz may also alter mental health symptoms, so psychiatric medicines should be used carefully.
• 5. Hepatitis B or C Medicines: Use cautiously with drugs like Interferon or Ribavirin, as the combination may cause liver toxicity.
• 6. Herbal Supplements: St. John’s Wort significantly lowers Efavirenz concentration, making Vianca less effective — avoid completely.
• 7. Alcohol: Alcohol increases the risk of liver damage and enhances dizziness or sleep disturbances caused by Efavirenz.
• 8. Kidney-Affecting Drugs: Concurrent use with NSAIDs (Ibuprofen, Diclofenac) or other nephrotoxic agents can worsen kidney function due to Tenofovir.
