Weight gain is not listed as a side effect of Gemtesa (vibegron) in the product information and there does not seem to be any anecdotal reports of weight gain from blog sites or Gemtesa reviews. Gemtesa does not cause weight gain.

It is possible that beta-3 agonists, such as Gemtesa, could promote weight loss. A small study that investigated mirabegron, another beta-3 agonists used for OAB, found that it also activated beta-3 receptors located in brown fat (adipose) tissue which boosted the participants' ability to burn energy, increasing the number of calories they burned. But this was a preliminary study and larger trials are needed.

Constipation is listed as a side effect of Gemtesa, but it is uncommon, occurring in less than 2% (2 out of every 100) people who take Gemtesa.

Cognitive decline, which may include dementia, memory loss and confusion, is not a known side effect for Gemtesa (vibegron) or the beta-3 agonist class as a whole. In addition, a study found the use of anticholinergic medications among patients with overactive bladder (OAB) was associated with an increased risk of new-onset dementia compared to beta-3 agonist users.

Gemtesa (vibegron) starts working almost immediately – within a few days of first taking it, with noticeable improvements in urinary urgency, frequency, and incontinence noted in clinical trials at 2 weeks which were reported as significant by 12 weeks.

After 12 weeks, people taking Gemtesa had 2 fewer daily leakage episodes compared to 1 fewer episode in those taking placebo, 2 fewer bathroom visits (versus 1 fewer with placebo), and 3 fewer “urge to go” visits a day compared to 2 fewer with placebo. Continue reading

Gemtesa (vibegron) works by relaxing the detrusor muscle of the bladder – this is smooth muscle found in the wall of the bladder – and it does this by activating beta-3 adrenergic receptors located in the detrusor muscle. By activating these receptors, the muscle in the bladder wall relaxes. This allows the bladder to hold more urine, which can relieve symptoms of overactive bladder such as needing to pass urine immediately or frequently (urinary urgency and frequency) and reduce urine leakage (urinary incontinence).
