Warnings

Incomplete absorption of glucose-galactose (Lapp lactase deficiency or galactose intolerance)

As Emeset contains lactose and therefore patients with galactose intolerance should not take this medicine.

Liver problems

Patients with liver problems should consult with the doctor. Also, for children who are on Emeset treatment in combination with chemotherapeutic agents having damaging effects on the liver should be monitored closely for any damage to the liver.

Masking of bleeding

Patients who have undergone the surgical procedure for removal of adenoids (patch of tissues behind the nose), for the prevention of nausea and vomiting with Emeset are at an increased risk of masking of bleeding. Such patients should be carefully monitored after giving Emeset.

Time taken for food to travel through the digestive tract (bowel transit time)

Patients with signs of subacute prevention of passage of digested food through the bowel (intestinal obstruction) should be monitored following dosage, as Emeset increases the large bowel transit time.

Genetic birth defect causing the build-up of an amino acid in the body (phenylketonuria)

Patients with phenylketonuria should be informed that Emeset orally disintegrating tablets contain phenylalanine, which is a component of sweetener.

Masking of progressive bloating of the stomach (ileus and gastric distension)

Patients using Emeset after the stomach surgery or in patients with chemotherapy-induced nausea and vomiting may mask a progressive ileus and gastric distension. Monitoring of decreased bowel activity, particularly in patients who are at an increased risk for stomach and intestinal blockage is recommended. Emeset should not be used to activate a series of muscle contractions in the digestive tract (gastric or intestinal peristalsis).

Life-threatening syndrome induced by use of serotonergic drugs (serotonin syndrome)

Patients who are on treatment with certain medicines (histamine receptor antagonists, serotonin reuptake inhibitors, serotonin, and norepinephrine reuptake inhibitors) are at an increased risk to develop serotonin syndrome which can be fatal in some cases. The syndrome has also occurred in patients after inducing a temporary loss of sensation (anesthesia) or in an infusion center. These patients may develop symptoms such as agitation, hallucinations, delirium, coma, increased heartbeat, sudden rise in blood pressure, dizziness, sweating (diaphoresis), flushing, increased body temperature, tremor, rigidity, sudden muscle contraction (myoclonus), overactive reflexes (hyperreflexia), incoordination, seizures, nausea, vomiting, or diarrhea. Such patients should be carefully monitored for the development of serotonin syndrome, occurring most commonly with the use of Emeset and other serotonergic drugs together. If any symptom of serotonin syndrome appears, the use of Emeset should be discontinued, and supportive treatment should be started.

Abnormal heartbeat (QT prolongation)

Patients consuming Emeset are at increased risk of developing abnormal heartbeat (QT prolongation). Avoid the use of Emeset in patients with abnormal heartbeat (congenital QT prolongation). An ECG monitoring is recommended in patients with congestive heart failure, slow heartbeat, electrolyte abnormalities, and abnormal heart rhythms.

Severe allergic reactions

Patients who are allergic to Emeset are at an increased risk when using this medicine. Such patients may have an increased risk of developing allergic reactions such as life-threatening allergic reaction (anaphylaxis) and tightening of the muscles of the lungs (bronchospasm). If such allergic reactions occur, the use of Emeset should be discontinued, and the patient should be monitored carefully until the signs and symptoms go away.

Interactions with Emeset

When two or more medicines are taken together, it can change how the medicines work and increase the risk of side-effects. In medical terms, this is called as a Drug Interaction.
Emeset Tablet may interact with serotonergic drugs, which are used to treat depression. The use of Emeset with serotonergic drugs may cause a life-threatening condition caused by the use of serotonergic drugs (serotonin syndrome). Such patients may experience symptoms like mental status changes, autonomic instability (e.g., high blood pressure, neuromuscular symptoms (e.g., tremor, rigidity), seizures, stomach and intestine symptoms (e.g., nausea, vomiting, diarrhea). Patients should be monitored for the exposure of serotonin syndrome. If any of these symptoms occur, discontinue the use of Emeset and provide supportive treatment.
There may be an interaction of Emeset with drugs affecting cytochrome P-450 enzymes (cyto3A4, cyto2D6, cyto1A2), which helps in the metabolism of the drug. The use of Emeset with cytochrome P3A4 inducers such as (phenytion, carbamazepine, rifampin) may decrease the level of Emeset in the blood. There is no requirement for dosage adjustment of Emeset in such patients.
Emeset Tablet interacts with tramadol, which is used to help relieve moderate to adequately severe pain. When Emeset is used in combination with tramadol, Emeset may reduce the pain-relieving effect of tramadol. Such patients should be monitored to ensure adequate pain control.
Special instructions need to be followed while taking this medicine along with apomorphine, which is used to treat Parkinson's disease. The use of Emeset with apomorphine may cause low blood pressure and loss of consciousness in the patients. The use of Emeset with apomorphine is not recommended.
Your doctor's guidelines may need to be followed while taking this medicine along with drugs that cause prolonged heartbeat (QT prolonging drugs). When Emeset is used with QT-prolonging drugs (such as doxorubicin, daunorubicin, trastuzimab, erythromycin, ketoconazole, amiodarone, atenolol or timolol) may increase the risk of irregular heartbeat. Take necessary precautions while taking Emeset with QT-prolonging drugs in such patients.
This page does not contain all the possible interactions of Emeset Tablet. Share a list of all medicines that you use with your doctor and pharmacist. Do not start, stop, or change the dose of any medicines without the approval of your doctor.

Traveling With Medication

  • Ensure that you carry enough doses of each of your prescription medicines to last the entire trip. The best place to store your medicines is in the carry on baggage. However, while flying, if carrying liquid medicines, make sure you do not go over the limits imposed for carry-on liquids.
  • While traveling overseas, make sure that you can carry each of your prescription medicines legally to your destination country. One way to ensure this is by checking with your destination country's embassy or website.
  • Make sure that you carry each of your medicines in their original packaging, which should typically include your name and address, and the details of the prescribing doctor.
  • If your travel involves crossing time zones, and you are required to take your medicine as per a fixed schedule, make sure that you adjust for the change in time.

Expired Medication

Taking a single dose of expired Emeset is unlikely to cause a side-effect. However, please discuss with your doctor or pharmacist, if you feel unwell or sick. An expired medicine may become ineffective in treating your prescribed conditions. To be on the safe side, it is important not to use an expired drug. You are much safer by always keeping a fresh supply of unexpired medicines.

Safe Disposal of Medication

  • If there are disposal instructions on the package, please follow the instructions.
  • If there are medicine take-back programs in your country, you should contact the respective authority to arrange for the disposal of the medicine. For example, in the USA, the Drug Enforcement Administration regularly hosts National Prescription Drug Take-Back events.
