Bisacodyl

What is bisacodyl?

Bisacodyl is a stimulant laxative used to treat short-term constipation in cats and dogs.

It is used off label (extra label) in veterinary medicine. Many drugs are commonly prescribed for off-label use in veterinary medicine. “Off label” means the drug is being used in a way that has not been reviewed or approved by the U.S. Food and Drug Administration (FDA) or Health Canada. In these instances, follow your veterinarian’s directions and cautions carefully, as they may be significantly different from those on the label.

How do I give my pet bisacodyl?

• Bisacodyl comes in tablet form. Suppositories and enemas are available, though not generally recommended for use in veterinary patients.
• Tablets are given orally (by mouth). Do not split or crush the tablets.
• Bisacodyl may be given with or without food (avoid dairy products). If your pet vomits or acts sick after receiving the drug on an empty stomach, try giving the next dose with food or a small treat. If vomiting continues, contact your veterinarian.
• Do not give antacids, milk, or other dairy products within one hour of this medication.
• If you are giving other medications to your pet by mouth, give them two hours apart from the bisacodyl.
• Give this medication to your pet for the entire time prescribed by your veterinarian, even if it appears that your pet is feeling better.

This medication should take effect within 1–2 days.

What if I miss giving my pet the medication?

If you miss a dose, give it as soon as you remember, and then continue with the regular dosing schedule. However, if it is almost time for the next dose, skip the missed dose and resume the regular dosing schedule. Do not give the pet two doses at once.
