What is Eliquis (Apixaban)?
Eliquis, the brand name for the medication apixaban, is a type of anticoagulant, commonly known as a blood thinner [1.2.6]. It is prescribed to reduce the risk of stroke and systemic embolism in patients with non-valvular atrial fibrillation (AFib). It is also used to prevent deep vein thrombosis (DVT), which can lead to pulmonary embolism (PE), in patients who have undergone hip or knee replacement surgery, and to treat DVT and PE [1.2.1, 1.2.9]. Apixaban works by inhibiting Factor Xa, a key component in the body's blood clotting process [1.6.9]. By blocking this factor, Eliquis decreases the ability of the blood to form clots.
Can Eliquis Affect Your Digestive System?
Yes, Eliquis can affect digestion and cause a range of gastrointestinal (GI) side effects [1.2.1, 1.3.1]. While many users tolerate the medication well, others may experience issues from mild discomfort to more severe complications. The most frequently reported digestive side effect is nausea, affecting about 3% of users in clinical trials [1.2.4]. Other reported common issues include constipation, diarrhea, dyspepsia (indigestion), and abdominal pain [1.3.2, 1.4.1].
Common Digestive Side Effects
Studies and patient reports have identified several digestive issues associated with Eliquis. These can include:
- Nausea: This is the most cited digestive complaint, though it often remains mild [1.2.2, 1.2.4]. Taking the medication with food or a small snack can help alleviate this symptom [1.2.4, 1.6.2].
- Constipation: Some studies have noted constipation as a side effect [1.3.2, 1.6.7].
- Diarrhea: Although less common and not always reported in clinical trials, some patients experience diarrhea [1.4.2, 1.4.9].
- Abdominal Pain and Indigestion (Dyspepsia): General stomach pain, discomfort, or indigestion have also been reported among users [1.3.2, 1.5.6].
It is important to note that sometimes these symptoms can be a sign of a more serious issue. For instance, nausea and stomach pain can also be early indicators of internal bleeding [1.4.5, 1.6.3].
The Serious Risk: Gastrointestinal Bleeding
The most significant and dangerous side effect of any anticoagulant, including Eliquis, is bleeding [1.2.6]. Because these medications work by preventing clots, they can also make it harder for the body to stop bleeding when it occurs. Gastrointestinal bleeding is a major risk associated with blood thinners [1.2.5, 1.3.1].
Signs of Gastrointestinal Bleeding
Patients taking Eliquis must be vigilant for signs of internal bleeding. Seek immediate medical attention if you experience any of the following symptoms [1.3.1, 1.6.6]:
- Red or black, tarry stools (melena)
- Vomiting blood or a substance that looks like coffee grounds
- Severe stomach pain
- Pink, red, or dark brown urine
- Unexplained fatigue, dizziness, or weakness (which can be signs of blood loss)
Managing Digestive Side Effects
For mild digestive issues like nausea or indigestion, simple measures can often help. Cleveland Clinic and other health resources suggest taking Eliquis with food if it upsets your stomach [1.2.9, 1.3.9]. It is also important to stay hydrated [1.2.4].
However, you should not take other medications without first consulting your doctor. For example, some over-the-counter antacids or pain relievers contain nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or aspirin, which can significantly increase the risk of bleeding when taken with Eliquis [1.2.1, 1.5.5].
Comparison of Anticoagulants and Digestive Side Effects
Different blood thinners can have varying effects on the digestive system. Understanding these differences can be helpful for patients and clinicians when choosing a treatment.
| Medication | Common Digestive Side Effects | Serious GI Risk | Management Notes |
|---|---|---|---|
| Eliquis (Apixaban) | Nausea (approx. 3%), constipation, dyspepsia, abdominal pain [1.2.4, 1.4.2]. | Gastrointestinal Bleeding [1.3.1]. | Can be taken with or without food; taking with food may reduce nausea [1.2.9]. Avoid NSAIDs [1.2.1]. |
| Xarelto (Rivaroxaban) | Abdominal pain, indigestion, nausea. | Gastrointestinal Bleeding. | Typically taken with food to ensure proper absorption. Avoid NSAIDs. |
| Warfarin (Coumadin) | Nausea, vomiting, abdominal cramps, bloating. | Gastrointestinal Bleeding [1.2.6]. | Requires regular blood monitoring and has many dietary (Vitamin K) and drug interactions [1.4.5]. |
| Pradaxa (Dabigatran) | Dyspepsia (indigestion) and gastritis-like symptoms are very common. | Gastrointestinal Bleeding. | Can be particularly harsh on the stomach lining for some patients. |
Conclusion
While Can Eliquis affect digestion? is a valid concern, the majority of digestive side effects, such as nausea, are mild and manageable for most patients [1.2.4]. The critical issue to monitor is the risk of gastrointestinal bleeding, a serious side effect of all anticoagulants [1.2.5]. Patients should be educated on the signs of internal bleeding—such as black, tarry stools or vomiting blood—and seek immediate medical help if they occur [1.3.5]. If you experience persistent or bothersome digestive issues while taking Eliquis, it is essential to speak with your healthcare provider to rule out serious complications and discuss management options.
