Does Gemtesa Cause Constipation?

Constipation is one of the common side effects of Gemtesa (vibegron). However, it’s important to note that according to the clinical trials, constipation is still only experienced in a relatively low number of patients. According to the trial, “The following adverse reactions (like constipation) have been identified during post-approval use of vibegron. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.” 

In the trial the number of placebo patients that had diarrhea or other gastrointestinal disorders from the 75mg dose went from 6% to 12%. The total number of patients in the trial was around 545. Making it still a relatively low number of patients that experienced an increase in gastrointestinal issues due to the medication.

How Long Do Side Effects Last

Gemtesa (vibegron) side effects can vary depending on the person. However, on average, side effects can last anywhere from a few days to a few weeks. The best course of action whenever any side effect is causing discomfort in your life is to speak with your PCP (primary care physician) about your medication and consider adjusting your dosage or considering an alternative medication.

How to Avoid Constipation While on Gemtesa (vibegron)

Easy methods to avoid constipation while on Gemtesa (vibegron) usually come from controlling your diet while on the medication. Here are our top tips:

1. Avoid spicy foods

Spicy foods may cause general gastrointestinal discomfort on their own, depending on who you are. When taken in combination with Gemtesa (vibegron), you could increase your chances of experiencing discomfort, along with the other side effects such as diarrhea. Avoid spicy foods that may cause general discomfort.

2. Avoid acidic foods

Acidic foods such as citrus fruits, red meats, and other non-alkaline foods can cause discomfort and difficulty with digestion. In order to keep your digestive system from having to struggle to digest highly acidic foods, avoid foods with low alkalinity.

3. Keep diet to whole foods

A whole food diet can be the best course of action to help with general digestion. This would be your basic meals such as chicken and rice. Or chicken and broccoli. Foods that have a higher pH level are going to be easier for your stomach acids to naturally break down, causing more regular bowel movements.
