Can Vesicare Cause Weight Gain?

Key Takeaways

  • Vesicare (solifenacin succinate) is not known to directly cause weight gain, and weight gain is not listed as a common side effect in FDA labeling.
  • Vesicare is an anticholinergic (antimuscarinic) medication used to treat symptoms of overactive bladder, such as urinary frequency and urinary incontinence.
  • Any weight changes reported while taking Vesicare are usually related to indirect factors like constipation, fluid retention, reduced activity, or other medical conditions.
  • Serious side effects such as urinary retention or allergic reaction are rare but require immediate medical attention.
  • A healthcare provider can help determine whether Vesicare or another factor is contributing to weight changes.

What Is Vesicare?

Vesicare is the brand name for solifenacin succinate. It is a prescription drug approved by the FDA to treat an overactive bladder. Overactive bladder is a condition marked by urinary urgency, urinary frequency, urge incontinence, and involuntary bladder contractions.

Vesicare belongs to a class of medications known as anticholinergics, or antimuscarinic drugs. These medications work by blocking muscarinic receptors in the bladder, helping relax bladder muscles and improve control over urination. Vesicare is typically taken as an oral tablet once daily and stored at room temperature.

Is Weight Gain a Known Side Effect of Vesicare?

Weight gain is not considered a common side effect of Vesicare. In clinical studies and FDA prescribing information, weight gain does not appear among the most frequently reported possible side effects of solifenacin.

The most common side effects of Vesicare are related to its anticholinergic effects and include dry mouth, constipation, blurred vision, dry eyes, and drowsiness. While some people may notice changes in appetite or digestion, Vesicare does not directly alter metabolism or fat storage in the body.

That said, some individuals report weight changes while taking Vesicare, which can lead to questions about whether the medication is responsible.

Why Weight Changes May Happen While Taking Vesicare

Although Vesicare does not directly cause weight gain, several indirect mechanisms may contribute to changes in body weight for some people.

Constipation and bloating

Constipation is a common side effect of solifenacin. In some cases, slowed digestion or gastric retention can lead to bloating or a feeling of fullness, which may be mistaken for weight gain. This effect is usually temporary and can be improved with dietary adjustments and hydration.

Fluid retention

Rarely, people may notice swelling in areas such as the lower legs. While not typical, fluid retention can cause short-term weight increases.

Reduced activity due to side effects

Drowsiness, blurred vision, or dry skin can make some people less active, particularly early in treatment. Reduced activity levels may indirectly contribute to gradual weight gain over time.

Other medical conditions

Underlying medical conditions such as kidney disease, liver disease, or hormonal imbalances can affect weight. These conditions may coexist with an overactive bladder but are not caused by Vesicare itself.

Common Side Effects of Vesicare

Common side effects of Vesicare include:

  • Dry mouth
  • Constipation
  • Blurred vision
  • Dry eyes
  • Drowsiness
  • Stomach pain

These side effects are related to Vesicare’s anticholinergic properties and usually appear early in treatment. Many improve as the body adjusts to the medication.

Serious Side Effects to Be Aware Of

Although uncommon, Vesicare can cause serious side effects that require prompt medical attention.

These include:

  • Increased risk of urinary retention
  • Angioedema or a severe allergic reaction, including swelling of the face, lips, or throat, trouble breathing, and hives or skin rash.
  • QT prolongation or irregular heart rhythm.
  • Heat stroke due to impaired sweating and changes in body temperature.

Life-threatening reactions are rare, but anyone experiencing these symptoms should seek medical attention immediately.

Vesicare Compared to Other Bladder Medications

Vesicare is one of several bladder medications used to treat an overactive bladder.

Other antimuscarinic options include oxybutynin and similar drugs, which share many anticholinergic side effects. Some patients who experience side effects with one medication may tolerate another better.

Mirabegron is an alternative treatment that works differently. It is not an anticholinergic and may be considered for people who cannot tolerate antimuscarinic side effects or who have concerns about dry mouth, constipation, or cognitive effects.

Drug Interactions and Special Precautions

Vesicare can interact with other prescription drugs and supplements. For example, ketoconazole can increase solifenacin levels in the body, raising the risk of side effects.

Vesicare should be used cautiously or avoided in people with:

  • Narrow-angle glaucoma
  • Severe urinary retention
  • Gastric retention
  • Certain heart rhythm conditions

Always inform a healthcare provider about all prescription drugs, over-the-counter products, and supplements you are taking.

Breastfeeding and Special Populations

It is not known whether solifenacin passes into breast milk. People who are breastfeeding should discuss risks and benefits with a healthcare provider before taking Vesicare.

Dose adjustments may also be necessary for people with kidney disease or impaired liver function.

What to Do If You Notice Weight Gain

If you notice weight gain while taking Vesicare:

  • Do not stop the medication abruptly.
  • Review recent dietary or activity changes.
  • Consider whether constipation or bloating may be contributing.
  • Contact a healthcare provider for medical advice.

Your provider may evaluate for other medical conditions, adjust the dose, or discuss alternative treatments if needed.

How to Take Vesicare Safely

  • Take Vesicare exactly as prescribed
  • Take one oral tablet daily, with or without food
  • If you miss a dose, take it when you remember, unless it is close to your next dose.
  • Do not take two doses at once.
  • Keep the medication out of the reach of children.

Bottom Line

Vesicare does not typically cause weight gain. While some people may notice changes in weight while taking solifenacin, these changes are usually caused by other factors, such as constipation, fluid retention, reduced activity, or other medical conditions. If weight gain is persistent or concerning, a healthcare professional can help determine the cause and adjust the treatment plan safely.
