By exploring these aspects, readers will gain valuable insights into Gemtesa’s role in treating overactive bladder and make informed decisions about their healthcare options.
What is Gemtesa and How Does It Work?
Gemtesa, also known by its generic name vibegron, is a prescription medication approved by the FDA in December 2020 for the treatment of overactive bladder (OAB) in adults. It belongs to a class of drugs called beta-3 adrenergic agonists and is manufactured by Urovant Sciences. It works by selectively targeting beta-3 adrenergic receptors in the bladder, which play a crucial role in regulating bladder function.
When Gemtesa binds to these receptors, it causes the detrusor smooth muscle in the bladder to relax. This relaxation increases bladder capacity, allowing it to hold more urine before the urge to urinate occurs. As a result, It helps reduce the symptoms associated with OAB, including urge urinary incontinence, urgency, and frequent urination.

Dosage and Administration
Gemtesa (vibegron) comes as a 75 mg oral tablet, taken once daily for the treatment of overactive bladder in adults. Patients should swallow the tablet whole with a full glass of water, with or without food. For those who have difficulty swallowing, the tablet can be crushed and mixed with a tablespoon of applesauce, then consumed immediately followed by a glass of water. It’s crucial to take Gemtesa at the same time each day to maintain consistent levels in the body. If a dose is missed, it should be taken as soon as remembered, unless it’s close to the next scheduled dose. In that case, the missed dose should be skipped. Patients should never take two doses at once to make up for a missed dose. Always follow the doctor’s prescription and instructions carefully when using Gemtesa.
Warnings and Precautions
Patients with known hypersensitivity to vibegron or any components of Gemtesa should not use this medication. Urinary retention has been reported in some patients taking Gemtesa, particularly those with bladder outlet obstruction or those using muscarinic antagonists for OAB treatment. Healthcare providers should monitor patients for signs of urinary retention and discontinue Gemtesa if it develops. Common side effects include headache, urinary tract infection, nasopharyngitis, diarrhea, nausea, and upper respiratory tract infection. Patients taking digoxin should have their serum concentrations measured before starting Gemtesa and monitored throughout treatment to adjust the digoxin dose as needed. It’s crucial to inform healthcare providers about all medications, including over-the-counter drugs and supplements, to prevent potential interactions.
Side Effects and Patient Monitoring
It may cause mild or serious side effects. Common side effects include headache, urinary tract infection, nasopharyngitis, diarrhea, nausea, and upper respiratory tract infection. Less than 2% of patients discontinue it due to side effects. Serious side effects, though rare, can occur. The most significant is urinary retention, especially in patients with bladder outlet obstruction or those taking other overactive bladder medications. Patients should contact their healthcare provider immediately if they experience difficulty emptying their bladder. Healthcare providers should monitor patients for signs of urinary retention and discontinue Gemtesa if it develops. Regular follow-ups are essential to assess the medication’s effectiveness and manage any potential side effects.
