-

- otherwise).

- take the missed dose as soon as possible, unless it is almost time for the
- next dose. In that case, do not take the missed dose at all; just return to
- your regular dosing schedule. Do not double the next dose. If you miss more
- than two doses in a row, CONTACT YOUR DOCTOR.
-
- SIDE EFFECTS
-
- Minor.
-
- Abdominal distress, fatigue, loss of appetite, nasal congestion, nausea,
- or vomiting. These side effects should disappear as your body adjusts to the
- medication. Methotrexate also causes hair loss, which is reversible when the
- medication is stopped.
- This medication can increase your sensitivity to sunlight. You should,
- therefore, try to avoid prolonged exposure to sunlight and sunlamps. Wear
- protective clothing and sunglasses, and use an effective sunscreen.
-
- Major.
-
- Tell your doctor about any side effects that are persistent or
- particularly bothersome. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about
- back pain, blurred vision, convulsions, diarrhea, difficult or painful
- urination, drowsiness, fever, headache, itching, menstrual changes, mouth
- sores, rash, severe abdominal pain, skin color changes, unusual bleeding or
- bruising, or yellowing of the eyes or skin.
-
- INTERACTIONS
-
- Methotrexate interacts with several other types of medications:
- 1. Concurrent use of alcohol and methotrexate can lead to an increased
- risk of liver damage.
- 2. Methotrexate can block the effectiveness of antigout medications.
- 3. Phenylbutazone, probenecid, phenytoin, tetracycline, aspirin,
- chloramphenicol, salicylates, naproxen, ketoprofen, and sulfonamide
- antibiotics can increase the blood levels of methotrexate, which can lead to
- an increase in serious side effects.
- 4. Methotrexate can increase the effects of the blood thinner warfarin,
- which can lead to bleeding complications.
- 5. Folic acid vitamins may decrease the effect of this medication.
- Before starting to take methotrexate, BE SURE TO TELL YOUR DOCTOR about
- any medications you are currently taking, especially any of those listed
- above.
-
- WARNINGS
-
- * Tell your doctor about unusual or allergic reactions you have had to
- any medications, especially to methotrexate.
- * Before starting to take this medication, be sure to tell your doctor if
- you now have or if you have ever had blood disorders, gout, infection, kidney
- disease, liver disease, or inflammation of the gastrointestinal tract.
- * If this drug makes you dizzy or drowsy, be careful going up and down
- stairs, and do not take part in any activity that requires alertness, such as
- driving a car or operating potentially dangerous machinery.
- * While you are taking methotrexate, you should drink plenty of fluids so
- that you urinate often (unless your doctor directs you to do otherwise). This
- helps prevent kidney and bladder problems during therapy.

- The vaccination or immunization will not be effective and may lead to an
- infection if a live-virus vaccine is used.
- * Methotrexate is a potent medication that can cause serious side
- effects. Your doctor will, therefore, want to monitor your therapy carefully
- with blood tests.
- * Be sure to tell your doctor if you are pregnant. Methotrexate has been
- shown to cause birth defects or death of the fetus. Effective contraception
- should be used during treatment and for at least eight weeks after treatment
- is stopped. Also, tell your doctor if you are breast-feeding an infant.
- Methotrexate passes into breast milk and can cause side effects in nursing
- infants.
