Karen - 24 Mar 2005 22:52 GMT I used to take Metho tablets, and on the info sheet that came with it, it said don't use alcohol while taking metho.
Now I'm on injectable and it doesn't give that warning? O.K. for alcohol???

Whatever information sheet you have, if it doesn't warn against alcohol, it isn't complete. Injectable has the same precautions as the tablets.
However, more than a few of us are wondering how you were able to get ahold of the injectable.
I'm a few weeks from running out myself. A few more weeks if I really want to stretch the unpreserved stuff.

Remember to store the unused portion in syringes, not the bottle.

Karen - 25 Mar 2005 02:06 GMT What do you mean to store it in syringes - not the bottle??? I only take out what I need each week. I don't want a bunch of syringes lying around!
>>No. >> [quoted text clipped - 15 lines] > > Walt Walt Hanks - 25 Mar 2005 03:53 GMT The manufacturer recommends that the unused portion be stored in syringes. The reason is this:
When you puncture the bottle with a syringe for the first time, bacteria is introduced into the bottle, and onto the rubber ring that seals the bottle. The concentration is particularly heavy on the surface of that rubber seal. If the bottle then sits around for a week before you draw again, those bacteria have had a lot of time to multiply and replenish the earth, so to speak.
So, the recommendation is that all the MTX be drawn at the same time with the unused portion stored in syringes. This keeps you from pushing a needle through a bacteria garden for your second or third draw from the bottle. Studies have shown that this is the most effective way to store unused portions of preservative free medications.
Hope that helps.

Was told it maybe well into June before the manufacturer is caught up and it is back in the pharmacies. I am on a waiting list around here.

O.K. for alcohol??? Nope. An occasional glass of wine or so is okay. But MTX in any form *can* increase liver enzymes, as can alcohol. So it is better not to drink. I did tell my RD I was having a glass of wine for Christmas and all he said was not to do it often. Funnily enough Christmas came and went without wine and I certainly didn't miss it. If I went out to a fancy restaurant for dinner I might have one. But regular drinking is not advisable. --- Joan

It's more about your physiologic state than anything else.

When I did ask re: another prescription, I was asked, "How much do you drink?" I replied, "A half glass of wine once or twice a week." (Really more than I do in fact drink.)
The RD and pharmacist both stated, in effect, "No problem. The drug companies, doctors and pharmacists use that "no alcohol" warning for the 6-pak a night alcoholic or wino."
A drug and alcohol combination can make a driver or heavy machinery operator twice as drowsy also. That is a worry, plus the organ damage that can occur with the combo.
In the next messages, I'm going to post two methotrexate findings I located today. Most, if not all, should be in an info folder you received with the prescription.
Shame, shame on your pharmacist if you did not.

I have to take exception to that last statement Chief. The key issue is your individual health. While a person with a healthy liver might be able to get away with a glass or two a week, a person with a mildly compromised liver might not. One needn't be a alcoholic for the restriction to be important.
Again, only your physician with your lab history in front of him or her can answer this question. No pharmacist has access to that information and, therefore, should defer the question to the personal physician.

That is like so many questions asked in ASA, which should be directed to a doctor rather than the lay people in here.

Methotrexate
SIDE EFFECTS: IN GENERAL, THE INCIDENCE AND SEVERITY OF ACUTE SIDE EFFECTS ARE RELATED TO DOSE AND FREQUENCY OF ADMINISTRATION.
The most frequently reported adverse reactions include ulcerative stomatitis, leukopenia, nausea, and abdominal distress. Other frequently reported adverse effects are malaise, undue fatigue, chills and fever, dizziness and decreased resistance to infection.
Other adverse reactions that have been reported with methotrexate arelisted below by organ system. In the oncology setting, concomitant treatment and the underlying disease make specific attribution of a reaction to methotrexate difficult.
Alimentary System: gingivitis, pharyngitis, stomatitis, anorexia, nausea,vomiting, diarrhea, hematemesis, melena, gastrointestinal ulceration and bleeding, enteritis, pancreatitis.
Blood and Lymphatic System Disorders: Suppressed hematopoiesis causing anemia, aplastic anemia, leukopenia and/or thrombocytopenia.
Hypogammaglobulinemia has been reported rarely.
Cardiovascular: pericarditis, pericardial effusion, hypotension, and thromboembolic events (including arterial thrombosis, cerebral thrombosis, deep vein thrombosis, retinal vein thrombosis, thrombophlebitis, and pulmonary embolus).
Central Nervous System: headaches, drowsiness, blurred vision. Aphasia, hemiparesis, paresis and convulsions have also occurred following administration of methotrexate. Following low doses, there have been occasional reports of transient subtle cognitive dysfunction, mood alteration, unusual cranial sensations, leukoencephalopathy, or encephalopathy.
Infection: There have been case reports of sometimes fatal opportunistic infections in patients receiving methotrexate therapy for neoplastic and non-neoplastic diseases. Pneumocystis carinii pneumonia was the most common infection. Other reported infections included nocardiosis; histoplasmosis, cryptococcosis, Herpes zoster, H. simplex hepatitis, and disseminated H. simplex.
Ophthalmic: conjunctivitis, serious visual changes of unknown etiology.
Pulmonary System: interstitial pneumonitis deaths have been reported, and chronic interstitial obstructive pulmonary disease has occasionally occurred.
Skin: erythematous rashes, pruritus, urticaria, photosensitivity, pigmentary changes, alopecia, ecchymosis, telangiectasia, acne, furunculosis, erythema multiforme, toxic epidermal necrolysis, Stevens-Johnson syndrome, skin necrosis, and exfoliative dermatitis.
Urogenital System: severe nephropathy or renal failure, azotemia,cystitis, hematuria; defective oogenesis or spermatogenesis, transient oligospermia, menstrual dysfunction, vaginal discharge and gynecomestia; infertility, abortion, fetal defects.
Other rarer reactions related to or attributed to the use of methotrexatesuch as nodulosis, vasculitis, opportunistic infection, arthralgia/myalgia, loss of libido/impotence, diabetes, osteoporosis, sudden death, and reversible lymphomas. Anaphylactoid reactions have been reported.
Adverse Reactions in Double-Blind Rheumatoid Arthritis Studies: The approximate incidences of methotrexate attributed (ie, placebo rate subtracted) adverse reactions in 12 to 18 week double-blind studies of patients (n=128) with rheumatoid arthritis treated with low-dose oral (7.5 to 15 mg/week) pulse methotrexate, are listed below. Virtually all of these patients were on concomitant nonsteroidal anti- inflammatory drugs and some were also taking low dosages of corticosteroids.
Incidence greater than 10%: Elevated liver function tests 15%, nausea/vomiting 10%.
Incidence 3% to 10%: Stomatitis, thrombocytopenia, (platelet count less than 100,000/mm3).
Incidence 1% to 3%: Rash/pruritus/dermatitis, diarrhea, alopecia, leukopenia (WBC less than 3000/mm3), pancytopenia, dizziness.
No pulmonary toxicity was seen in these two trials. Thus, the incidence is probably less than 2.5% (95% C.L.). Hepatic histology was not examined in these short-term studies. (See PRECAUTIONS.)
Other less common reactions included decreased hematocrit, headache, upperrespiratory infection, anorexia, arthralgias, chest pain, coughing, dysuria, eye discomfort, epistaxis, fever, infection, sweating, tinnitus, and vaginal discharge.
Adverse Reactions in Psoriasis There are no recent placebo-controlled trials in patients with psoriasis. There are two literature reports (Roenigk, 1969 and Nyfors, 1978) describing large series (n=204, 248) of psoriasis patients treated with methotrexate. Dosages ranged up to 25 mg per week and treatment was administered for up to four years. With the exception of alopecia, photosensitivity, and "burning of skin lesions" (each 3% to 10%), the adverse reaction rates in these reports were very similar to those in the rheumatoid arthritis studies.
Adverse Reactions in JRA Studies The approximate incidences of adverse reactions reported in pediatric patients with JRA treated with oral, weekly doses of methotrexate (5 to 20 mg/m2/wk or 0.1 to 0.65 mg/kg/wk) were as follows (virtually all patients were receiving concomitant nonsteroidal anti-inflammatory drugs, and some also were taking low doses of corticosteroids); elevated liver function tests, 14%; gastrointestinal reactions (e.g., nausea, vomiting, diarrhea), 11%; stomatitis, 2%; leukopenia, 2%; headache, 1.2%; alopecia, 0.5%, dizziness, 0.2%; and rash, 0.2%. Although there is experience with dosing up to 30 mg/m2/wk in JRA, the published data for doses above 20 mg/m2/wk are too limited to provide reliable estimates of adverse reaction rates.
DRUG INTERACTIONS Concomitant administration of some NSAIDs with high dose methotrexate therapy has been reported to elevate and prolong serum methotrexate levels, resulting in deaths from severe hematologic and gastrointestinal toxicity.
Caution should be used when NSAIDs and salicylates are administered concomitantly with lower doses of methotrexate. These drugs have been reported to reduce the tubular secretion of methotrexate in an animal model and may enhance its toxicity.
Despite the potential interactions, studies of methotrexate in patients with rheumatoid arthritis have usually included concurrent use of constant dosage regimens of NSAIDs, without apparent problems. It should be appreciated, however, that the doses used in rheumatoid arthritis (7.5 to 15 mg/week) are somewhat lower than those used in psoriasis and that larger doses could lead to unexpected toxicity.
Methotrexate is partially bound to serum albumin, and toxicity may beincreased because of displacement by certain drugs, such as salicylates, phenylbutazone, phenytoin, and sulfonamides. Renal tubular transport is also diminished by probenecid; use of methotrexate with this drug should be carefully monitored.
Oral antibiotics such as tetracycline, chloramphenicol, and nonabsorbable broad spectrum antibiotics, may decrease intestinal absorption of methotrexate or interfere with the enterohepatic circulation by inhibiting bowel flora and suppressing metabolism of the drug by bacteria.
Penicillins may reduce the renal clearance of methotrexate; increased serum concentrations of methotrexate with concomitant hematologic and gastrointestinal toxicity have been observed with high and low dose methotrexate. Use of methotrexate with penicillins should be carefully monitored.
The potential for increased hepatotoxicity when methotrexate is administered with other hepatotoxic agents has not been evaluated.
However, hepatotoxicity has been reported in such cases. Therefore,patients receiving concomitant therapy with methotrexate and otherpotential hepatotoxins (e.g., azathioprine, retinoids, sulfasalazine)should be closely monitored for possible increased risk of hepatotoxicity.
Methotrexate may decrease the clearance of theophylline; theophylline levels should be monitored when used concurrently with methotrexate.
Vitamin preparations containing folic acid or its derivatives may decreaseresponses to systemically administered methotrexate. Preliminary animal and human studies have shown that small quantities of intravenously administered leucovorin enter the CSF primarily as 5- methyltetrahydrofolate and in humans, remain 1 - 3 orders of magnitude lower than the usual methotrexate concentrations following intrathecal administration. However, high doses of leucovorin may reduce the efficacy of intrathecally administered methotrexate.
Folate deficiency states may increase methotrexate toxicity.
Trimethoprim/sulfamethoxazole has been reported rarely to increase bone marrow suppression in patients receiving methotrexate, probably by an additive antifolate effect.

Methotrexate
Brand name: Methotrexate Pronounced: meth-oh-TREX-ate Brand names: Rheumatrex, Trexall
Why is this drug prescribed?
Methotrexate is an anticancer drug used in the treatment of lymphoma (cancer of the lymph nodes) and certain forms of leukemia. It is also given to treat some forms of cancers of the uterus, breast, lung, head, neck, and ovary.
Methotrexate is also given to treat rheumatoid arthritis when other treatments have proved ineffective, and is sometimes used to treat very severe and disabling psoriasis (a skin disease characterized by thickened patches of red, inflamed skin often covered by silver scales).
Most important fact about this drug
Be certain to remember that in the treatment of psoriasis and rheumatoid arthritis, methotrexate is taken once a week, not once a day. Accidentally taking the recommended weekly dosage on a daily basis can lead to fatal over- dosage. Be sure to read the patient instructions that come with the package.
How should you take this medication?
Take methotrexate exactly as prescribed, and promptly report to your doctor any new symptoms that may develop.
Methotrexate is given at a higher dosage for cancer than for psoriasis or rheumatoid arthritis. After high-dose methotrexate treatment, a drug called leucovorin may be given to limit the toxic effects.
--If you miss a dose... Skip it and go back to your regular schedule. Do not take 2 doses at once.
--Storage instructions... Store at room temperature, away from light.
What side effects may occur?
Side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Only your doctor can determine whether it is safe for you to continue taking methotrexate.
More common side effects may include: Abdominal pain and upset, chills and fever, decreased resistance to infection, dizziness, fatigue, general feeling of illness, mouth ulcers, nausea
Less common side effects may include: Abortion, acne, anemia, birth defects, black or tarry stool, boils, bruises, changes in skin coloration, convulsions, diarrhea, drowsiness, eye or vision problems, fatigue, hair loss, headaches, hives, inability to speak, infection of hair follicles, infertility, inflammation of the gums or mouth, intestinal inflammation, kidney failure, loss of appetite, lung disease, menstrual problems, partial or complete paralysis, rash or itching, red patches on skin, sensitivity to light, skin peeling or flaking, sore throat, stomach and intestinal ulcers and bleeding, stomach pain, vaginal discharge, vomiting, vomiting blood
Rare side effects may include: Diabetes, impotence, infection, joint pain, loss of sexual desire, muscular pain, osteoporosis, ringing in the ears, severe allergic reaction, shortness of breath, sleepiness, sudden death, sweating
If you are taking methotrexate for psoriasis, you may also experience hair loss and/or sun sensitivity, and your patches of psoriasis may give a burning sensation.
Methotrexate can sometimes cause serious lung damage that makes it necessary to limit the treatment. If you experience a dry cough, fever, or breathing difficulties while taking methotrexate, be sure to tell your doctor right away.
During and immediately after treatment with methotrexate, fertility may be impaired. Men may have an abnormally low sperm count; women may have menstrual irregularities.
People on high doses of methotrexate may develop a brain condition signaled by confusion, partial paralysis, seizures, or coma.
Why should this drug not be prescribed?
Do not take this medication if you are sensitive to it or it has given you an allergic reaction.
Do not take this medication if you are pregnant.
Methotrexate treatment is not suitable for you if you suffer from psoriasis or rheumatoid arthritis and also have one of the following conditions:
Abnormal blood cell count Alcoholic liver disease or other chronic liver disease Alcoholism Anemia Immune-system deficiency
Special warnings about this medication
Before you start taking methotrexate, your doctor will do a chest X-ray plus blood tests to determine your blood cell counts, liver enzyme levels, and the efficiency of your kidney function. While you are taking methotrexate, the blood tests will be repeated at regular intervals; if you develop a cough or chest pain, the chest X-ray will be repeated.
If you are being treated for psoriasis or rheumatoid arthritis, your doctor will test your liver function at regular intervals. You should avoid alcoholic beverages while taking this drug.
You may develop an opportunistic infection--one that takes advantage of your altered body chemistry--while you are taking methotrexate. Before receiving an immunization or vaccination, be sure to inform health care workers that you are taking this drug.
Older or physically debilitated people are particularly vulnerable to toxic effects from methotrexate. Your doctor will prescribe methotrexate with great caution if you have any of the following:
Active infection Liver disease Peptic ulcer Ulcerative colitis
Possible food and drug interactions when taking this medication
If you are being given methotrexate for the treatment of cancer or psoriasis, you should not take aspirin or other nonsteroidal painkillers such as Advil or Naprosyn; this combination could increase the toxic effects of methotrexate. If you are taking methotrexate for rheumatoid arthritis, you may be able to continue taking aspirin or a nonsteroidal painkiller, but your doctor should monitor you carefully.
Other drugs that may increase the toxic effects of methotrexate include:
Cisplatin (Platinol) Penicillins Phenylbutazone Phenytoin (Dilantin) Probenecid Retinoid drugs such as Retin-A and Renova Sulfa drugs such as Bactrim and Gantrisin
Sulfa drugs may increase methotrexate's toxic effect on the bone marrow, where new blood cells are made.
Certain antibiotics, including tetracycline (Sumycin) and chloramphenicol (Chloromycetin), may reduce the effectiveness of metho?trexate. This is also true of vitamin preparations that contain folic acid.
In addition, methotrexate can alter the effect of theophylline (Quibron, Theo-Dur).
Special information if you are pregnant or breastfeeding
A woman should not start methotrexate therapy until the doctor is sure she is not pregnant. Because methotrexate causes birth defects and miscarriages, it must not be taken during pregnancy by women with psoriasis or rheumatoid arthritis. It should be taken by women being treated for cancer only if the potential benefit outweighs the risk to the developing baby. In fact, a couple should avoid pregnancy if either the man or the woman is taking methotrexate. After the end of methotrexate treatment, a man should wait at least 3 months, and a woman should wait for the completion of at least one menstrual cycle, before attempting to conceive a child.
Methotrexate should not be taken by a woman who is breast- feeding; it does pass into breast milk and may harm a nursing baby.
Recommended dosage
Treatment with methotrexate is highly individualized. Your doctor will carefully tailor your dosage of methotrexate in order to avoid serious side effects and possible under- or overdosing.
Overdosage
Taken in excess, methotrexate can cause serious and even fatal damage to the liver, kidneys, bone marrow, lungs, or other parts of the body. Symptoms of overdosage may include lung or breathing problems, mouth ulcers, or diarrhea.
Initially, however, serious damage caused by methotrexate may be apparent only in the results of blood tests. For this reason, careful, regular monitoring by your doctor is necessary. If for any reason you suspect symptoms of an overdose of this drug, seek medical attention immediately.
