Anti-emetic guidance for systemic anti cancer therapy (SACT) (S\Tox\15)

Emesis is a well recognised side effect associated with the use of systemic anti-cancer therapy (SACT).  These guidelines are intended to provide guidance on the use of anti-emetics as prophylaxis and treatment of nausea and vomiting associated with use of SACT.

For guidance on use of anti-emetics during radiotherapy, refer to the anti-emetic guideline for radiotherapy treatment.

Treatment goals and assessment of risk

  • Prevention and optimal control of nausea and vomiting.  Poor control may lead to delayed emesis within first treatment cycle and emesis with subsequent cycles.   
  • For combination regimes, choose an antiemetic according to the SACT agent with the greatest degree of risk (See Table 4 & 5 for agent classification). In addition to SACT agent, the following patient factors should be considered (Table 1). 
  • If there are two drugs of the same emetic class being used or a very susceptible patient then the anti-emetic regime of the next higher class should be considered. 
  • ACUTE symptoms – occur within 24 hours of last SACT dose (5HT3 pathways appear to dominate).      
  • DELAYED symptoms – 24 hours to 7 days of last SACT dose. 
  • Rescue anti-emetics should be given to patients to use “as required” for poorly controlled symptoms.  If nausea & vomiting (N&V) controlled, consider regular rather than prn dosing and choice of any additional agents should be based on assessment of appropriate administration route and disease related issues e.g. brain metastases, electrolyte disturbances, opioids, infection, tumour infiltration of bowel or gastric obstruction. The chosen anti-emetic should not aggravate symptoms e.g. metoclopramide and gastric obstruction, 5HT3 antagonist and constipation. 
  • Anticipatory nausea - use the most active antiemetic appropriate for the SACT being administered to prevent acute or delayed emesis. Antiemetics should be used with initial cycle rather than assessing response.  Consider lorazepam given orally on the night before and the morning of chemotherapy.  
  • ADMINISTRATION NOTE: Where prescribed intravenously, dexamethasone should be administered slowly (bolus over several minutes or infused over 15 – 30 minutes). If required intravenously, 5HT3 antagonists (granisetron or ondansetron) should be administered as an infusion over 15 minutes and not bolused. Note that concurrent administration of steroids can enhance the efficacy of 5HT3 antagonists.

80mg OD D2&3

Caution in mod / severe hepatic impairment 

Multiple interactions – see Additional prescribing notes 

Administer day 1 dose 1 hour before treatment 

Cyclizine 25-50mg 8 hourly IV/SC or 100-150mg CSCI pump over 24 hours  50mg TDS

Antimuscarinic side effects (dry mouth, blurred vision, constipation, hypotension and confusion. Slows peristalsis in GI tract. Useful if nausea lingering after first three days and metoclopramide not fully controlling. 

Caution in epilepsy.

Dexamethasone 8-20mg IV pre-SACT

8-20mg pre-SACT

2-4mg BD post-SACT

May cause perineal discomfort if given by rapid IV bolus. In practice doses > 8mg should be given as an infusion over 15 mins. 

May induce / unmask/ destabilise diabetes – advise patients of symptoms of thirst / increased diuresis, increase BM monitoring in patients with diabetes as per ECC guidelines. May cause dyspepsia when used at high dose for prolonged course - consider PPI prophylaxis as per ECC policy. 

Domperidone N/A 10mg TDS Suppositories and oral liquid available

Note not preferred choice anti-emetic. Due to MHRA advice the use of domperidone should now be reserved for treatment of nausea / vomiting. It is not a preferred option. 

Due to the risk of sudden cardiac death in patients >60 with prolonged QT interval it should not be used in patients with identifiable risk factors and is contra-indicated in patients with underlying cardiac conditions, severe hepatic impairment, and in patients receiving other QT prolonging medicines or potent CYP3A4 inhibitors (e.g. itraconazole, fluconazole & clarithromycin). Restrict use to a maximum of 7 days. Consider baseline ECG if prescribing. The MHRA recommends use at the lowest possible dose for the shortest possible duration (max of 30mg per day). 

Fosaprepitant 150mg IV infusion over 20-30mins N/A

For patients unable to swallow oral NKI (akynzeo or aprepitant) 

Drug should be prepared on ward and administered as a 1mg/ml solution using method below:  

  1. Inject 5 ml sodium chloride (0.9%) into the vial assuring that this is added along the vial wall in order to prevent foaming. Swirl vial gently and avoid shaking.  
  1. Removing 105 ml of sodium chloride (0.9%) solution from a 250 ml sodium chloride (0.9 %) infusion bag, leaving 145mls.  
  1. Withdraw the entire volume from the vial and transfer it into an infusion bag containing 145 ml of sodium chloride (0.9%) to yield a total volume of 150 ml (1mg/ml).  Gently invert the bag 2-3 times and administer over 20-30 minutes. 
Granisetron 1-2mg IV

1-2mg OD. Can be used BD if OD dosing is ineffective.

Sancuso® patch (32mg over 7 days).

1 patch applied 24–48 hours prior to SACT and to remain in place for a max of 7 days.

May reduce lower bowel motility, patients with signs of sub-acute intestinal obstruction should be monitored following administration.  As for other 5-HT3 antagonists, ECG changes including QT interval prolongation have been reported. Therefore, caution should be exercised in patients with cardiac rhythm or conduction disturbances, in patients using other medications that prolong QT interval (see Table 7), in patients treated with anti-arrhythmic agents or beta-adrenergic blocking agents and in patients with significant electrolyte disturbances (low potassium, magnesium or calcium).  Concomitant use of cardio-toxic drugs (e.g. anthracyclines) may increase risk of arrhythmias. 

Common side effects: headache and constipation  - consider laxatives, caution in patients with history of migraines.

Consider granisetron patch for patients on multi-drug regimens where patients have swallowing difficulties. For any other indication MMC approval is required. Apply patch to a dry hairless area on the outer part of the upper arm.  Patch could also be applied to the abdomen if arm is not possible. Patches should not be cut into pieces.  Showering / bathing is permitted with the patch but patients should avoid direct heat / saunas.  The patch should be covered by clothing and protected from direct natural or artificial sunlight for duration of wear and area protected for or up to 10 days after removal.

Levomepromazine

5–25mg CSCI over 24 hours    or  2.5mg SC injection 8-12hrly PRN  

N/A S/C administration can be used for patients admitted with N&V. Use low doses in first instance to avoid sedation and hypotension. Avoid in liver dysfunction. Rare Reports of QT prolongation therefore care in patients with low potassium, calcium and magnesium levels and other drugs known to prolong QT interval
Lorazepam 0.5–1mg IV up to TDS  0.5–1mg up to TDS (sublingual)  Useful for patients who are anxious or who experience anticipatory nausea and vomiting 
Metoclporamide 5-10mg IM or IV 6-8 hourly (max 30mg in 24 hours)

10mg TDS or 6 hourly prn  

Max of 3 doses in 24hrs 

(oral liquid available)

The EMEA issued advice on use of metoclopramide in 2013 (ECC metoclopramide statement) restricting the dose and duration of use of the medicine to minimise the known risks of potentially serious neurological SE’s. 

Metoclopramide is associated with agitation and extra-pyramidal symptoms particularly in young females, in addition prolonged use may lead to neurological side effects in elderly patients in particular. Caution is advised in patients with parkinsons disease and taking concurrent neuroleptics. Bowel transit time can be reduced and it is contra-indicated in GI obstruction.  

The recommended single dose is 10 mg, repeated up to three times daily. The max recommended daily dose is 30 mg or 0.5mg/kg body weight.  

The max duration of regular treatment is 5 days, after which it can be taken as required. Regular use for longer than 5 days can be considered in patients who remain poorly controlled and are without risk factors at the prescriber’s discretion. 

Ondansetron

8-16 mg IV infusion (infuse over a minimum of 15 mins)  

Max dose IV=16mg;  (in patients over 75 yrs, max dose IV=8mg)

8mg BD (usual dose) 

Dose range 4-8mg up to TDS #

Repeat IV doses should be given no less than 4 hrs apart. 

Administer with caution to patients who have or may develop prolongation of QTc.(see above for information beside granisetron). Ondansetron is known to increase large bowel transit time, patients with signs of sub-acute intestinal obstruction should be monitored following administration. 

Interactions: Potent inducers of CYP3A4 such as phenytoin, carbamazepine, and rifampicin, may increase the oral clearance of ondansetron and decrease ondansetron blood concentrations. Data from small studies indicate that ondansetron may reduce the analgesic effect of tramadol. 

# Melts formulation available for patients unable to swallow tablets – useful alternative 5HT3 antagonist for this situation. 

Olanzapine N/A

5-10mg once daily (usually at night) 

3rd line treatment option 

Adults who experience nausea or vomiting despite optimal prophylaxis should be offered olanzapine in addition to continuing the standard antiemetic regimen.   

5-10mg pre-SACT then 5-10mg OD for 3 days following SACT. 

Available as tablets or orodispersible tablets for patients unable to swallow tablets. 

Causes drowsiness – caution with driving. 

Caution should be used if olanzapine is being administered concomitantly with medicinal products known to increase QTc interval. 

May be pro-epileptogenic so should be used with caution with patients with difficult to control seizures.

Palonosetron

250mcg STAT 

(no additional 5HT3 given)

500mcg (1 capsule) PO approximately one hour prior to SACT.  (preferential to IV dosing) 

Only for patients in whom steroids are C/I or compliance is in doubt.  For other indications MMC approval is required. Risk of QTc prolongation as for other 5HTs antagonists (refer to granisetron cautions). 

May increase large bowel transit time therefore monitor in patients with constipation or potential SABO.  Capsules contain sorbitol and lecithin derived from soya therefore patients with known sensitivity to soya or peanuts should be monitored closely for hypersensitivity reactions. 

Evidence (ASCO guidelines) suggests palonosetron is superior to ondansetron or granisetron during period of 24–120 hours post SACT but non-significant difference in first 24 hours therefore good if delayed emesis a particular problem.

Prochlorperazine

5–10mg 2–3 times a day 

Deep IM 12.5mg if required

5-10mg 2-3 times daily or 

Buccastem® 3-6mg BD

May cause drowsiness.  Avoid in liver or renal dysfunction, parkinsons disease, cardiac failure and hypothyroidism. 

Buccal preparation (Buccastem®) useful for the vomiting patient as absorbed from the oral mucosa. Place tablet between upper lip and gum and leave to dissolve.
