Does Gemtesa cause weight gain?

No, Gemtesa isn’t known to cause weight gain. Weight changes weren’t reported in the drug’s studies.

But it’s important to note that having overweight or obesity can worsen OAB symptoms, which the drug is prescribed to treat.

If you’re concerned about your weight while taking Gemtesa, talk with your doctor. They may recommend ways to manage your weight as part of your OAB treatment plan.

Gemtesa is used in adults who have the following urinary symptoms caused by overactive bladder (OAB):

  • urge incontinence (a sudden urge to urinate followed by losing control of your bladder)
  • urgency (needing to urinate right away)
  • frequency (needing to urinate often)

OAB is a condition that causes a sudden urge to urinate, and it may cause incontinence (not being able to control urination). These symptoms are often unpredictable, which can affect your daily life.

The exact cause of OAB is unknown. But the symptoms are caused by your bladder muscles contracting involuntarily. This sends signals to your brain that you need to urinate, even if your bladder isn’t full. It can also cause your bladder to release urine suddenly.

Gemtesa works to treat symptoms of OAB by sending signals that relax your bladder muscles. This allows your bladder to fill to capacity before sending your brain signals that you need to urinate.

Your doctor will explain how you should take Gemtesa. They’ll also explain how much to take and how often. Be sure to follow your doctor’s instructions.

Taking Gemtesa

Gemtesa comes as tablets that you swallow. You should take the tablets with a full glass of water.

Accessible medication containers and labels

If it’s hard for you to read the label on your prescription, tell your doctor or pharmacist. Certain pharmacies may provide medication labels that:

  • have large print
  • use braille
  • contain a code you can scan with a smartphone to change the text into audio

Your doctor or pharmacist may be able to recommend a pharmacy that offers these options if your current pharmacy doesn’t.

Also, if you’re having trouble opening your medication bottles, let your pharmacist know. They may be able to put Gemtesa in an easy-open container. Your pharmacist may also recommend tools to help make it simpler to open the drug’s container.

Questions for your doctor

You may have questions about Gemtesa and your treatment plan. It’s important to discuss all your concerns with your doctor.

Here are a few tips that might help guide your discussion:

  • Before your appointment, write down questions such as:
    • How will Gemtesa affect my body, mood, or lifestyle?
  • Bring someone with you to your appointment if doing so will help you feel more comfortable.
  • If you don’t understand something related to your condition or treatment, ask your doctor to explain it to you.

Remember, your doctor and other healthcare professionals are available to help you. And they want you to get the best care possible. So don’t be afraid to ask questions or offer feedback on your treatment.

Before you begin taking Gemtesa, it’s important to discuss certain considerations with your doctor. This includes any medical conditions you may have or other medications you take.


Taking a medication with certain vaccines, foods, and other things can affect how the medication works. These effects are called interactions.

Before taking Gemtesa, be sure to tell your doctor about all medications you take, including prescription and over-the-counter types. Also, describe any vitamins, herbs, or supplements you use. Your doctor or pharmacist can tell you about any interactions these items may cause with Gemtesa.

For information about drug-condition interactions, see the “Warnings” section below.

Interactions with drugs or supplements

Gemtesa can interact with the heart drug digoxin (Lanoxin). It’s usually safe to take digoxin with Gemtesa, but your doctor may monitor you more closely during treatment.

Your doctor or pharmacist can tell you more about this interaction.


Gemtesa may not be right for you if you have certain medical conditions. These are known as drug-condition interactions. Other factors may also affect whether Gemtesa is a good treatment option for you.

Talk with your doctor about your health history before you take Gemtesa. Factors to consider include those in the list below.

  • Severe kidney problems. In most cases, it should be safe for people with mild or moderate kidney problems (such as mild chronic kidney disease) to take Gemtesa. But if you have a severe kidney problem, such as end-stage kidney disease, your doctor will likely suggest a treatment other than Gemtesa. Gemtesa hasn’t been studied in people with severe kidney problems. To learn more, talk with your doctor.
  • Severe liver problems. People with mild or moderate liver problems are usually able to take Gemtesa. But the drug hasn’t been studied in people with severe liver problems. It’s not known if the drug is safe to take if you have severe liver problems. Alcohol-related liver disease is an example of a liver problem that can be mild, moderate, or severe. Your doctor can tell you more about how severe your liver condition is. They can also discuss treatments that may be safer for you instead.
  • Trouble emptying your bladder or a weak urine stream. Gemtesa can cause urinary retention. If you already have difficulty emptying your bladder, using Gemtesa could worsen your condition. Your doctor can determine whether it’s safe for you to take Gemtesa.
  • Allergic reaction. If you’ve had an allergic reaction to Gemtesa or any of its ingredients, your doctor will likely not prescribe Gemtesa. Ask them what other medications are better options for you.

Gemtesa and alcohol

There’s no known interaction between Gemtesa and alcohol. But alcohol and Gemtesa can cause some of the same side effects, including headache, diarrhea, and nausea. Combining the two could raise your risk of these side effects.

In addition, alcohol may worsen symptoms of overactive bladder. This is because alcohol can cause you to urinate more often, which may irritate your bladder.

If you drink alcohol, talk with your doctor about how much, if any, may be safe to drink with your condition and treatment plan.

Pregnancy and breastfeeding

It’s not known whether it’s safe to use Gemtesa while pregnant or breastfeeding.

If you’re pregnant or breastfeeding, or planning to become pregnant or breastfeed, talk with your doctor about whether Gemtesa is right for you.

Do not take more Gemtesa than your doctor prescribes. Taking more than this can lead to serious side effects.

What to do in case you take too much Gemtesa

Call your doctor if you think you’ve taken too much Gemtesa. You can also call 800-222-1222 to reach America’s Poison Centers or use its online resource. But if you have severe symptoms, immediately call 911 or your local emergency number. Or go to the nearest emergency room.

If you’re interested in learning more about Gemtesa for treating overactive bladder (OAB) symptoms, talk with your doctor. Ask questions to help determine whether Gemtesa or another treatment is right for you. Some example questions to get you started include:

  • Do any of my medical conditions raise my risk of side effects from Gemtesa?
  • If I frequently get urinary tract infections (UTIs), is it safe for me to take Gemtesa?
  • What should I do if my OAB symptoms worsen while I’m taking Gemtesa?
