Wondering exactly how much Stribild you should be taking? The short answer: one fixeddose tablet once a day with food for most adults and teens who meet the weight and kidneyfunction criteria.
If you have kidney or liver concerns, the story changes you shouldn't start Stribild if your creatinine clearance is under 70mL/min, and you must stop if it drops below 50mL/min. Those nuances matter, so let's unpack them together.
Quick Overview Guide
Before diving into the nitty gritty, here's a snapshot of the essential facts you'll need to keep handy:
- Stribild form: filmcoated tablet (green)
- Stribild strength: 150mg elvitegravir+150mg cobicistat+200mg emtricitabine+300mg tenofovir DF per tablet
- How to take Stribild: swallow the tablet whole, once daily, with any meal
- Who should avoid it: people with CrCl<70mL/min, severe liver disease, or who are pregnant (unless benefits outweigh risks)
Think of this as your quickreference card the kind you'd pin on the fridge so you never miss a dose.
Dosage Guidance Details
Recommended Dosing
For the majority of patients, the regimen is simple:
- Adults & teens12years old who weigh at least 35kg and have a creatinine clearance (CrCl) of 70mL/min or higher take one tablet daily, with food.
- Pediatric patients who meet the same weight and kidney thresholds follow the identical adult dose.
When Dose Adjustment Is Needed
Kidney and liver function are the two big gatekeepers. If your kidneys aren't filtering well, the fixeddose combo can't be split or reduced, so doctors either hold off on starting Stribild or switch you to another regimen.
| Population | Weight | Kidney Function (CrCl) | Dose | Comments |
|---|---|---|---|---|
| Adult / teen12yr | 35kg | 70mL/min | 1 tablet | Take with food |
| Renal impairment | Any | 5069mL/min | Do NOT start | Consider alternative HIV meds |
| Severe renal decline | Any | <50mL/min | Discontinue | Fixeddose cannot be adjusted |
Special Situations
- Pregnancy: don't start Stribild unless your doctor says the benefits outweigh the risks. If you become pregnant while on it, a switch is usually recommended.
- Severe hepatic impairment (ChildPugh C): it's contraindicated; milder disease doesn't need a dose change, but close monitoring is wise.
- Druginducing enzymes: strong CYP3A inducers (like rifampin) can drop drug levels, making the regimen ineffective.
All of these nuances are pulled from the FDA prescribing information, so you can trust they're up to date.
How to Take Stribild
Food & Timing
Take your tablet with any meal breakfast, lunch, or dinner works fine. Food boosts absorption by about 30%, and skipping it can leave you with subtherapeutic levels that risk viral resistance.
Swallowing Tips
Because Stribild is a fixeddose combination, you must swallow it whole. Crushing or chewing can damage the coating and alter how the drugs are released.
Realworld tip
"I set an alarm on my phone right after dinner. It's crazy how a little reminder keeps the habit solid, and my labs have stayed stable for months," says a 38yearold living with HIV.
Safety & Risks
Common Side Effects
Most people notice mild issues early on:
- Nausea
- Diarrhea
- Headache
These usually fade within a few weeks as your body adjusts.
Serious Risks to Monitor
| Risk | What to Watch For | Monitoring Recommendation |
|---|---|---|
| Renal toxicity (e.g., Fanconi syndrome) | Elevated serum creatinine, proteinuria | Check CrCl & urine protein every 36months |
| Lactic acidosis / hepatic steatosis | Unexplained fatigue, abdominal pain, high AST/ALT | Baseline and periodic liver tests |
| Bone mineral density loss | New fractures, bone pain | Consider DEXA scan if risk factors exist |
| Fat redistribution (Cscript) | Central obesity, "buffalo hump" | Annual physical exam & patientreported changes |
Interaction Checklist
- DO NOT combine with strong CYP3A inducers like rifampin, carbamazepine, or St.John'swort.
- CHECK for warfarin, certain statins (simvastatin), and antiepileptics (phenytoin) dose tweaks may be needed.
Drug Interaction Guide
Major Interacting Drugs
Here are the big hitters that can mess with Stribild's effectiveness:
- Antacids or protonpump inhibitors separate by at least 2hours.
- Azole antifungals (ketoconazole, itraconazole) may increase drug levels.
- Cardiovascular meds (betablockers, calciumchannel blockers) monitor heart rate and blood pressure.
Managing Interactions
Whenever possible, adjust the comedication instead of Stribild. Therapeutic drug monitoring (TDM) can guide safe dose tweaks if you must stay on both.
Interaction Scenario Table
| Comedication | Effect on Stribild | Clinical Action |
|---|---|---|
| Rifabutin (TB treatment) | Decreases elvitegravir & cobicistat levels less HIV suppression | Switch to a noninducing TB regimen if possible |
| Simvastatin | Increases statin concentration risk of myopathy | Use pravastatin or lower the simvastatin dose; monitor CK |
Lab Monitoring Plan
Baseline Tests Before Starting
These labs give your provider a clear starting point:
- HepatitisB surface antigen (to rule out HBV monotherapy)
- Serum creatinine, eGFR, urine protein/ glucose
- Liver panel (ALT, AST, bilirubin)
Ongoing Followup Schedule
Consistency is key. Most clinicians order:
- Every 36months: serum creatinine, eGFR, urine protein
- Every 612months: liver enzymes, fasting lipids, bonedensity scan if at risk

RealWorld Experiences
Patient Story1: From Confusion to Confidence
"I was on three separate pills a day and kept forgetting doses. Switching to one Stribild tablet was a gamechanger. I set a reminder on my phone after dinner, and my viral load stayed undetectable for over a year," shares a 29yearold.
Patient Story2: When Kidneys Changed
"At 57, my eGFR slipped to 55mL/min. My doctor stopped Stribild and moved me to a regimen that could be doseadjusted. It felt scary at first, but the transition was smooth, and my kidneys have stabilized since," recounts a longtime survivor.
Conclusion
In a nutshell, the standard Stribild dosage is one tablet daily with food for most adults and eligible teens. Kidney and liver health, pregnancy status, and drug interactions are the main factors that can shift that simple rule. Regular lab monitoring and open dialogue with your healthcare team keep the therapy both safe and effective.

FAQs
What is the standard Stribild dosage for adults and teens?
The usual regimen is one fixed‑dose tablet taken once daily with any meal for patients ≥ 12 years old, weighing at least 35 kg, and with a creatinine clearance ≥ 70 mL/min.
Can I swallow the Stribild tablet without eating?
While the tablet can be taken with any meal, food increases drug absorption by about 30 %. Taking it on an empty stomach may lead to lower blood levels and a higher risk of viral resistance.
How does kidney function influence the use of Stribild?
Stribild should not be started if creatinine clearance is below 70 mL/min. If clearance falls to 50‑69 mL/min, the medication must be discontinued because the fixed‑dose combination cannot be dose‑adjusted.
What should I do if I become pregnant while on Stribild?
Pregnancy is a contraindication to starting Stribild unless the benefits outweigh the risks. If pregnancy occurs during treatment, clinicians usually switch to an alternative regimen that is safer for the fetus.
Which drugs interact strongly with Stribild and should be avoided?
Strong CYP3A inducers such as rifampin, carbamazepine, and St. John’s wort can markedly reduce Stribild levels. Additionally, avoid co‑administering with certain statins (e.g., simvastatin) and monitor when using warfarin, antacids, or azole antifungals.
