If you take Suboxone (buprenorphine-naloxone) for opioid addiction treatment, you probably already know that it’s meant to dissolve under your tongue or inside your cheek—but what about food?
- Should you take Suboxone on an empty stomach or after eating?
- Can certain foods affect how well it absorbs?
- What if you feel nauseous after taking it?
While food doesn’t drastically reduce Suboxone’s effectiveness, what you eat—and when you eat—can affect how quickly it absorbs and whether you experience side effects like nausea.
We’ll explain how food affects Suboxone absorption, whether you should take it before or after eating, and what to do if it upsets your stomach.
Does Eating Affect Suboxone Absorption?
How Suboxone Enters the Body
Suboxone is taken sublingually (under the tongue) or buccally (inside the cheek), where it absorbs directly into the bloodstream through the thin membranes in the mouth.
Unlike swallowed medications, Suboxone does NOT pass through the stomach or liver before it reaches the bloodstream, meaning food has minimal impact on its effectiveness.
Key Takeaway: Food does NOT block Suboxone from working, but eating right before or after taking it may still cause some issues.
Should You Take Suboxone on an Empty Stomach or After Eating?
Taking Suboxone on an Empty Stomach: Pros & Cons
Pros:
- Some people find faster absorption when taking Suboxone on an empty stomach.
- Reduces the risk of food particles interfering with absorption.
Cons:
- Can sometimes cause nausea or dizziness, especially in the early days of treatment.
- If you’re prone to low blood sugar, it may make you feel lightheaded.
Best for: People who don’t experience nausea or dizziness on an empty stomach.
Taking Suboxone After Eating: Pros & Cons
Pros:
- Helps prevent nausea and stomach discomfort.
- Eating beforehand can stabilize blood sugar, reducing dizziness.
Cons:
- Food and drink can leave residue in the mouth, which may slightly reduce absorption.
- Some foods, especially acidic ones (citrus, soda), can alter your mouth’s pH, potentially affecting how Suboxone dissolves.
Best for: People who experience nausea, dizziness, or stomach upset when taking medication on an empty stomach.
Foods & Drinks That May Interfere with Suboxone Absorption
While food doesn’t directly block Suboxone, certain foods and drinks can make absorption less effective.
Avoid These Before Taking Suboxone
- Citrus fruits (oranges, grapefruit, lemon, lime): The acidity can alter pH levels in the mouth, potentially affecting absorption.
- Soda & energy drinks: These are highly acidic, which may impact how well Suboxone dissolves.
- Coffee or tea: Can dry out the mouth, reducing saliva and affecting absorption.
- Mouthwash or minty gum before dosing: Alcohol-based mouthwashes can dry out oral membranes, reducing absorption.
What’s Best to Eat or Drink Before Taking Suboxone?
- Plain water (to rinse the mouth).
- Light, non-acidic foods like oatmeal, toast, or yogurt if you’re prone to nausea.
Key Tip: If you eat before taking Suboxone, rinse your mouth with water first to clear food residue and improve absorption.
Common Stomach Issues with Suboxone & How to Fix Them
While Suboxone is generally well-tolerated, some people experience nausea, bloating, or stomach discomfort when taking it—especially in the early stages of treatment.
1. Suboxone Nausea & Upset Stomach
- Why it happens: Your body is adjusting to buprenorphine, or you’re taking it on an empty stomach.
- How to fix it:
- Eat a light meal (avoid greasy or spicy foods).
- Take deep breaths before dosing—this helps relax the stomach.
- If nausea persists, talk to your doctor about adjusting your dose.
2. Suboxone & Bloating or Gas
- Why it happens: Buprenorphine can slightly affect digestion, or you may be swallowing too much saliva while it dissolves.
- How to fix it:
- Avoid carbonated drinks before taking Suboxone.
- Try eating smaller, more frequent meals instead of large meals.
- Don’t talk while Suboxone dissolves—this can cause air swallowing, leading to bloating.
3. Acid Reflux or Heartburn After Taking Suboxone
- Why it happens: If you’re prone to acid reflux, Suboxone may trigger increased stomach acid production.
- How to fix it:
- Avoid acidic foods & drinks (coffee, citrus, soda).
- Try taking a small snack before dosing to buffer stomach acid.
- Use an antacid (Tums, Pepto-Bismol) if needed—but avoid taking it at the same time as Suboxone.
Best Practices for Taking Suboxone for Maximum Effectiveness
To get the best results from your Suboxone dose:
- Rinse your mouth with water before taking Suboxone to remove food or drink residue.
- Let the film/tablet fully dissolve—don’t chew or swallow it.
- To ensure full absorption, avoid eating or drinking anything (except water) for at least 15–30 minutes after dosing.
- If you experience nausea, try taking it after a small meal and stay hydrated.
- If side effects persist, talk to your doctor about possible dose adjustments.
