Instgra Dolutegravir 50 Mg Tablets

Q1: What is Instgra Dolutegravir 50mg used for?

Instgra is a branded formulation of Dolutegravir 50mg, an INSTI used as a key component of HIV combination therapy. It is prescribed as part of complete triple therapy regimens and is a WHO-recommended first-line agent.

Q2: How does Instgra/Dolutegravir differ from older HIV drugs?

Dolutegravir works at the integrase step — a different HIV replication target than older NNRTIs and PIs. It requires no pharmacokinetic boosting, has the highest genetic barrier to resistance among INSTIs, fewer drug interactions than PIs, and is safe during pregnancy.

Q3: How is Instgra 50mg taken?

Take 50mg once daily, ideally on an empty stomach, at a consistent time each day. In patients on rifampicin or efavirenz, the dose increases to 50mg twice daily. Antacids, iron, calcium, and magnesium supplements must be separated by at least 2 hours.

Q4: What resistance properties make Dolutegravir durable?

Dolutegravir requires multiple integrase resistance mutations to lose activity — a very high genetic barrier. Clinical resistance to Dolutegravir in treatment-naive patients is exceedingly rare, making it one of the most durable HIV drugs available.

Q5: What are the most common side effects of Instgra?

Insomnia and headache are most commonly reported. Nausea, diarrhea, and dizziness can occur. Neuropsychiatric effects (anxiety, depression, mood changes, vivid dreams) affect a minority of patients, particularly those with pre-existing psychiatric conditions.

Q6: What neuropsychiatric effects require medical attention?

While insomnia and mild mood changes are common, significant depression, suicidal thoughts, or psychosis warrant immediate medical evaluation. Some patients require switching to an alternative INSTI if neuropsychiatric effects are intolerable.

Q7: What monitoring is needed during Instgra therapy?

CD4 count and viral load at baseline, then 4–8 weeks, then every 3–6 months. Serum creatinine may increase slightly (Dolutegravir inhibits tubular secretion of creatinine — this is not a sign of kidney damage). Liver function at baseline and periodically.

Q8: Does Dolutegravir interact with HIV medications?

Dolutegravir has fewer interactions than PIs. Key interactions: rifampicin and efavirenz require 50mg twice daily dosing. Antacids, iron, and mineral supplements reduce absorption. Metformin levels increase significantly — monitor and reduce metformin dose.

Q9: Is Instgra safe during pregnancy?

Yes. After initial concerns about neural tube defects were refuted by larger studies, Dolutegravir is now recommended in pregnancy by WHO and many national guidelines. Discuss with your HIV and obstetric specialists.

Q10: Can Instgra be used alone as monotherapy?

Dolutegravir dual therapy (with Lamivudine only) is an evidence-based option for virologically suppressed patients in some guidelines. However, standard triple therapy remains the default — monotherapy with Dolutegravir alone is not recommended.

Q11: How should Instgra 50mg be stored?

Store at room temperature away from light and moisture. Keep in original packaging out of reach of children.

Q12: Do I need a prescription for Instgra?

Yes. Dolutegravir requires specialist HIV prescribing, baseline viral load and CD4 count assessment, and regular monitoring throughout treatment.
