Anticoagulant administration
Rivaroxaban: strength, food and tube location change the instructions
A once-daily tablet is not automatically a fasting-compatible tablet. Adult rivaroxaban administration depends on strength, and a crushed dose also requires a check of where the feeding tube ends.

Read the strength before giving a food instruction
The label distinguishes adult 15 mg and 20 mg tablets from the 2.5 mg and 10 mg tablets. Food is required for the higher strengths. Saying that every rivaroxaban tablet can be taken without food erases a strength-specific administration requirement.
For nonvalvular atrial fibrillation, the adult dosing table specifies the evening meal. Other indications have their own regimen and transition steps. This article tests administration, not a shortcut for selecting a dose from one remembered indication.
Crushing does not remove the food requirement
The label allows tablets to be crushed and mixed with applesauce immediately before oral use. After a crushed 15 mg or 20 mg tablet, food should follow immediately. The smaller adult tablet strengths do not have that same food requirement.
Check the actual dosage form before applying tablet instructions to a suspension. Pediatric VTE and post-Fontan instructions are also indication-specific. A statement about an adult 10 mg tablet is not a complete instruction for every pediatric use.
Confirm the feeding-tube endpoint
For tablets administered through a nasogastric or gastric feeding tube, the label says to confirm gastric placement, crush and suspend the tablet in 50 mL of water, and avoid release distal to the stomach. Absorption depends on the site of release.
A jejunal tube is therefore not interchangeable with a gastric tube for this instruction. After a crushed 15 mg or 20 mg tablet, enteral feeding should follow immediately. Flushing a tube does not substitute for the required feeding step.
Separate feasibility from anticoagulant selection
An administration plan can fail even when the dose was otherwise selected correctly. The pharmacist must check strength, food, preparation and tube endpoint together, rather than approving the order because the tablet is crushable.
Changing the route, stopping anticoagulation or selecting a different agent needs clinical review. The case identifies why a proposed route is unsupported; it does not give a replacement regimen for a particular patient.
A worked case
A patient has an adult Xarelto 20 mg order and a feeding tube whose tip is in the jejunum. A plan says to crush the tablet, give it through the tube and omit feeding because it is a tablet. Identify the two administration problems.
- Twenty milligrams retains a food or immediate-enteral-feeding requirement after crushing.
- The label supports gastric placement and says to avoid release distal to the stomach.
- The tube endpoint and feeding plan both need review before administration.
Answer: Crushability alone does not make this plan acceptable. The jejunal route and omitted feeding conflict with the cited instructions.
Try it before reading the answer
Write the key fact, decision and safety check first. These are original practice exercises, not recalled exam items.
1. Does an adult 20 mg tablet require food?
Yes.
2. Does permission to crush establish suitability for a jejunal tube?
No. The label says to avoid administration distal to the stomach.
3. Do adult 2.5 mg and 10 mg tablets share the same food requirement?
No. The cited tablet instructions do not require food for those strengths.
