What Are the Side Effects of Trulance? A Comprehensive Guide

Living with chronic constipation or irritable bowel syndrome with constipation (IBS-C) can significantly impact your quality of life. For many sufferers, medications like Trulance (plecanatide) offer relief from these challenging digestive conditions. However, as with any medication, understanding potential side effects is crucial for making informed decisions about your treatment plan.

This comprehensive guide explores the common and rare side effects of Trulance, who should avoid this medication, and what alternatives might be available for those seeking digestive relief.

Understanding Trulance and How It Works

Trulance is a prescription medication approved by the FDA to treat chronic idiopathic constipation (CIC) and irritable bowel syndrome with constipation (IBS-C) in adults. The active ingredient, plecanatide, works by increasing fluid in your intestines and accelerating bowel movements, making it easier to pass stool.

Unlike some other constipation treatments, Trulance mimics a naturally occurring peptide in your body called uroguanylin, which regulates fluid balance in the GI tract. This mechanism of action helps restore normal bowel function rather than simply forcing bowel movements like some laxatives do.

The Science Behind Plecanatide

Plecanatide activates guanylate cyclase-C receptors on the intestinal epithelium, increasing intracellular and extracellular cyclic guanosine monophosphate (cGMP). This process enhances secretion of chloride and bicarbonate into the intestinal lumen, increasing intestinal fluid and accelerating transit. The medication is designed to work primarily in the small intestine and colon where pH levels are optimal for its activation.

Because Trulance works locally in the gut and has minimal systemic absorption (less than 0.1%), it tends to have fewer whole-body side effects compared to some other medications that enter the bloodstream in larger amounts.

Common Side Effects of Trulance

Clinical trials have shown that Trulance is generally well-tolerated by most patients. However, like all medications, it can cause side effects. Understanding what to expect can help you determine whether any symptoms you experience are normal or require medical attention.

Diarrhea

The most commonly reported side effect of Trulance is diarrhea, affecting approximately 5% of patients in clinical studies. This makes sense given the medication's mechanism of action to increase intestinal fluid. For most people, diarrhea is mild to moderate and typically resolves as your body adjusts to the medication.

However, if you experience severe diarrhea while taking Trulance, it's important to contact your healthcare provider immediately. Severe or persistent diarrhea can lead to dehydration and electrolyte imbalances, which may require medical intervention.

Abdominal Discomfort

Some patients report experiencing abdominal discomfort, including bloating, gas, or mild cramping, especially during the initial days of treatment. These symptoms often subside as your body adjusts to the medication. Taking Trulance with food might help minimize these effects, although the medication can be taken with or without food according to prescribing information.

If abdominal pain becomes severe or is accompanied by fever or bloody stools, seek medical attention promptly as these could indicate a more serious condition unrelated to normal side effects.

Headache and Dizziness

Though less common than digestive symptoms, some patients report experiencing headaches or dizziness while taking Trulance. These symptoms may be related to fluid shifts in the body or, in some cases, might be secondary to dehydration if the patient experiences diarrhea. Staying well-hydrated while taking Trulance can help minimize these effects.

The intensity of headaches can vary from mild discomfort to more pronounced pain. Some patients find that taking over-the-counter pain relievers like acetaminophen can help manage these symptoms, but it's always advisable to consult with your healthcare provider before combining medications. Dizziness typically manifests as a feeling of lightheadedness when standing up quickly, which can be exacerbated if you're experiencing fluid loss from diarrhea. If dizziness persists or worsens, it could indicate a more significant issue with blood pressure or dehydration that warrants medical evaluation.

Tracking when these symptoms occur—whether they appear shortly after taking Trulance or at specific times during the day—can provide valuable information for your healthcare provider. Some patients find that adjusting the timing of their dose, such as taking it in the evening rather than morning, can help minimize the impact of these side effects on daily activities. Remember that your body's response to medication is unique, and what works best for symptom management may require some personalized adjustments under medical supervision.

Rare but Serious Side Effects

While most side effects of Trulance are mild and manageable, there are some rare but serious adverse reactions that require immediate medical attention.

Severe Diarrhea

In clinical trials, about 0.4% of patients experienced severe diarrhea. Severe diarrhea can lead to dehydration, which may cause symptoms like extreme thirst, dry mouth, decreased urination, dizziness, and fatigue. If you experience severe or persistent diarrhea while taking Trulance, stop taking the medication and contact your healthcare provider immediately.

Patients who are particularly vulnerable to complications from dehydration, such as elderly individuals or those with certain medical conditions, should be especially vigilant about this potential side effect.

Allergic Reactions

Although rare, allergic reactions to Trulance can occur. Signs of an allergic reaction may include rash, itching, swelling (especially of the face, tongue, or throat), severe dizziness, or trouble breathing. If you experience any of these symptoms after taking Trulance, seek emergency medical attention immediately.

Who Should Avoid Taking Trulance?

While Trulance can be effective for many adults with chronic constipation or IBS-C, it's not appropriate for everyone. Understanding contraindications can help prevent serious adverse events.

Children and Adolescents

Trulance carries a boxed warning against use in children under 18 years of age. In studies with young laboratory animals, the medication caused severe dehydration and death. Although these effects haven't been observed in human children, the risk is considered significant enough that the medication is contraindicated in pediatric patients.

The FDA has placed its strongest warning on Trulance regarding this issue, emphasizing that the medication should never be given to children under 18 years old.

Bowel Obstruction

Patients with known or suspected mechanical gastrointestinal obstruction should not take Trulance. The medication increases intestinal fluid, which could worsen an obstruction and lead to serious complications. If you have symptoms of a bowel obstruction (severe abdominal pain, vomiting, inability to pass gas or stool), seek immediate medical attention rather than taking constipation medication.

Managing Side Effects and Maximizing Benefits

If you and your healthcare provider decide that Trulance is appropriate for your condition, there are several strategies that may help minimize side effects while maximizing the medication's benefits.

Dietary Considerations

While taking Trulance, maintaining a balanced diet rich in fiber can complement the medication's effects. However, for those with IBS-C, certain high-fiber foods might trigger symptoms. Many patients find relief by following a low FODMAP diet, which limits fermentable carbohydrates that can exacerbate IBS symptoms.

For those interested in supporting gut health while on Trulance, Casa de Sante offers low FODMAP certified, gut-friendly protein powders and digestive enzymes that can be incorporated into your dietary routine. These products are specifically formulated to support digestive health without triggering IBS symptoms, making them a valuable complement to medical treatments like Trulance.

Hydration and Electrolyte Balance

Since diarrhea is the most common side effect of Trulance, maintaining proper hydration is essential. Drink plenty of water throughout the day, and consider beverages that contain electrolytes if you experience loose stools. Some patients find that taking Trulance with a meal helps reduce the intensity of digestive side effects.

For those experiencing mild diarrhea, Casa de Sante's prebiotic and probiotic supplements may help restore balance to the gut microbiome, potentially easing digestive disturbances while your body adjusts to the medication.

Alternative Treatments for Chronic Constipation and IBS-C

If Trulance isn't suitable for you due to side effects or other factors, several alternative treatments are available for chronic constipation and IBS-C.

Other Prescription Medications

Several other prescription medications target chronic constipation and IBS-C through different mechanisms. Linzess (linaclotide) works similarly to Trulance but may have a slightly different side effect profile. Amitiza (lubiprostone) increases intestinal fluid secretion through a different pathway. Your healthcare provider can help determine which medication might be most appropriate based on your specific symptoms and medical history.

Natural Approaches

Many patients prefer to try natural approaches before or alongside prescription medications. Increasing dietary fiber, staying well-hydrated, and maintaining regular physical activity can significantly improve constipation symptoms for some individuals. Herbal supplements like Casa de Sante's gentle herbal laxative formulation offer a natural alternative for occasional constipation relief without harsh stimulants.

For those managing IBS-C, a personalized approach often yields the best results. Casa de Sante's personalized meal plans can help identify trigger foods while ensuring adequate nutrition, potentially reducing the need for medication in some cases.
