Nodolor (Isometheptene Mucate / Dichloralphenazone / Acetaminophen) - Warnings and Precautions

 
 



Liver Warning

This product contains acetaminophen. Severe liver damage may occur if a person takes:

  • More than 4,000 mg of acetaminophen in 24 hours
  • With other drugs containing acetaminophen
  • With 3 or more alcoholic drinks everyday while using this product.
 

PRECAUTIONS

Caution should be observed in hypertension, peripheral vascular disease and after recent cardiovascular attacks.

This drug may make you dizzy or drowsy. Do not drive, use machinery, or do any activity that requires alertness until you are sure you can perform such activities safely. Avoid alcoholic beverages. Remember that alcohol may be a cause of headaches.

DRUG INTERACTIONS

This drug should not be used with the following medications because very serious interactions may occur: sodium oxybate.

Avoid MAO inhibitors (isocarboxazid, linezolid, methylene blue, moclobemide, phenelzine, procarbazine, rasagiline, selegiline, or tranylcypromine) within 2 weeks before, during, and after treatment with this medication. In some cases a serious (possibly fatal) drug interaction may occur.

Consider drugs that cause drowsiness such as: certain antihistamines (e.g., diphenhydramine), anti-seizure drugs (e.g., carbamazepine, phenytoin), medicine for sleep or anxiety (e.g., alprazolam, diazepam, zolpidem), muscle relaxants (e.g., cyclobenzaprine), narcotic pain relievers (e.g., codeine), psychiatric medicines (e.g., chlorpromazine, risperidone, trazodone).

This medication may interfere with certain laboratory tests (including certain urine glucose tests, urine catecholamine levels, urine 5-HIAA levels), possibly causing false test results.

PREGNANCY

FDA has not assigned a pregnancy category for Nodolorâ„¢ Capsules. Acetaminophen is routinely used for short-term pain relief and fever in all stages of pregnancy.

Acetaminophen crosses the placenta and is believed to be safe in pregnancy when used intermittently for short durations. No controlled studies have been done to establish the safety of dichloralphenazone or isometheptene or of their combination with acetaminophen. Nodolorâ„¢ Capsules should only be given during pregnancy when need has been clearly established.

NURSING MOTHERS

Acetaminophen is excreted into human milk in small concentrations. Metabolites of dichloralphenazone are excreted into human milk. There are no data on the excretion of isometheptene into human milk. Problems in humans have not been documented.

PEDIATRIC USE

Studies with this medicine have been done only in adult patients, and there is no specific information about its use in children.

GERIATRIC

There is no specific published information comparing use of this combination medicine in the elderly with use in other age groups. Geriatric patients are more likely to have peripheral vascular disease, and are therefore more likely to be adversely affected by peripheral vasoconstriction, than are younger adults. However, isometheptene may be safer for elderly patients than the ergot derivatives used to abort acute vascular headaches. Also, elderly patients are more likely to have age related renal function impairment, which may require caution in patients receiving acetaminophen and isometheptene.
