In some cases, factors or conditions could prevent your doctor from prescribing Motegrity due to the risk of harm. These are known as contraindications. The contraindications of Motegrity include:

Having a tear or blockage in your intestine

Your doctor likely won’t prescribe Motegrity if you have a perforation (tear) in the wall of your intestine. And they’ll likely not prescribe Motegrity if you have a blockage in your intestine caused by a problem with the structure or function of your intestine.

Taking Motegrity increases the muscular contractions in your intestine, which could be dangerous in these situations. Ask your doctor about other treatments that may be better choices for you.

Having severe inflammatory bowel disease

If you have severe inflammatory bowel disease (IBD), your doctor will likely not prescribe Motegrity. Examples of severe IBD include Crohn’s disease, ulcerative colitis, and toxic megacolon.

Taking Motegrity increases the muscular contractions in your intestine, which could be dangerous in these situations. Ask your doctor about other treatments that may be better choices for you.

Having had an allergic reaction to Motegrity or any of its ingredients

If you have had an allergic reaction to Motegrity or any of its ingredients, your doctor will likely not prescribe Motegrity. Taking the drug could cause another allergic reaction. You can ask them about other treatments that may be better choices for you.

Note: Before you start treatment with Motegrity, it’s important to tell your doctor if these contraindications apply to you. They can determine whether to prescribe Motegrity.

There aren’t any known interactions between Motegrity and alcohol. However, your doctor may advise you to avoid or limit alcohol consumption during Motegrity treatment.

If you consume alcohol during Motegrity treatment, these side effects may be more likely to occur. If you have questions about drinking alcohol while taking Motegrity, talk with your doctor.

Here’s a closer look at a drug interaction of Motegrity.

Fosfomycin (Monurol)

Fosfomycin (Monurol) is an antibiotic prescribed to treat some urinary tract infections (UTIs) caused by bacteria.

Interaction result: Taking Motegrity with fosfomycin could make this antibiotic less effective.

Interaction explained: Motegrity increases the muscular contractions in your intestines, so it can make fosfomycin move through your digestive system faster than it should. This can reduce the amount of fosfomycin that’s absorbed into your bloodstream and then excreted in your urine. Excreting a lower amount of fosfomycin in your urine can make the drug less effective at treating a UTI.

Steps you or your doctor may take: To treat a UTI, fosfomycin is taken as a single dose. If your doctor prescribes fosfomycin with Motegrity, they may recommend taking your fosfomycin dose at a different time of day than your Motegrity dose.

If you still have UTI symptoms after taking fosfomycin with Motegrity, talk with your doctor.
