Beer And Gleevec: A Safe Mix?

Gleevec (imatinib) is a prescription medication used to treat certain types of cancer, such as blood cancer, gastrointestinal cancer, and skin cancer. It is typically taken orally as a tablet, and can be taken with or without food. While there are no known interactions between alcohol and Gleevec, both substances may cause similar side effects, including nausea and vomiting. As such, drinking alcohol during Gleevec treatment may increase the risk of these side effects. Additionally, alcohol can cause liver damage, and combining it with Gleevec may further increase the risk of liver problems. Therefore, it is recommended to consult a doctor about the safe amount of alcohol to consume while taking Gleevec.

Gleevec and alcohol interaction

Gleevec (imatinib) is a brand-name oral tablet used to treat certain types of cancer, including blood cancer, gastrointestinal cancer, and skin cancer. It works by slowing or stopping the growth of cancer cells. While alcohol is not known to interact with Gleevec, drinking alcohol while taking this medication is not recommended, as it may increase the risk of certain mild side effects, including nausea, diarrhea, headache, and fatigue. Both alcohol and Gleevec can cause these side effects, and their combination may increase the risk of experiencing them.

Additionally, alcohol use while taking Gleevec may increase the risk of liver damage, a possible serious side effect of the medication. Alcohol can cause liver damage, and combining it with Gleevec may further elevate this risk. It is important for individuals taking Gleevec to consult their doctor about alcohol consumption and to ask about the safe amount of alcohol, if any, that can be consumed while taking this medication.

Grapefruit juice is another beverage that should be avoided during treatment with Gleevec. Grapefruit juice can increase the blood levels of imatinib and may enhance the chance of side effects. If an individual has been regularly consuming grapefruit juice or grapefruit products, they should consult their doctor before discontinuing, as this may also alter the effects of the medication.

It is worth noting that Gleevec may cause mild and serious side effects, similar to other drugs. Some of the more common mild side effects include edema (fluid retention), mild skin problems like rashes, and nasopharyngitis (swelling of the throat and nasal passages, known as the common cold). Serious side effects may include blood disorders, gastrointestinal issues, heart problems, kidney damage, liver damage, severe edema, severe hemorrhage, and tumor lysis syndrome.

Gleevec side effects

Gleevec (imatinib) is a brand-name oral tablet prescribed for some types of blood cancer in adults and some children. It is also used to treat certain types of gastrointestinal cancer and skin cancer in adults. As with other drugs, Gleevec can cause mild and serious side effects.

Common side effects of Gleevec

Some of the more common side effects reported by people who took Gleevec in clinical studies include:

• Edema, also called fluid retention (excess fluid that can cause swelling of the feet, ankles, and legs)
• Mild skin problems, such as a rash
• Nasopharyngitis (swelling of the throat and nasal passages, known as the common cold)

Mild side effects of Gleevec

Mild side effects can occur when taking Gleevec. This list doesn’t include all possible mild side effects of the drug. Some of the mild side effects that have been reported with Gleevec include:

• Edema, also called fluid retention (excess fluid that can cause swelling of the feet, ankles, and legs)
• Mild skin problems, such as a rash
• Nasopharyngitis (swelling of the throat and nasal passages, known as the common cold)

Serious side effects of Gleevec

Gleevec may cause serious side effects. The list below may not include all possible serious side effects of the drug. If you develop serious side effects while taking Gleevec, call your doctor right away. If the side effects seem life-threatening, immediately call 911 or your local emergency number. Serious side effects that have been reported include:

• Blood disorders, such as anemia (low levels of red blood cells), neutropenia (low levels of white blood cells), and thrombocytopenia (low platelet levels). Symptoms can include blood in urine or stool
• Gastrointestinal (stomach or intestinal) problems, including perforations (tears). Symptoms can include severe abdominal pain
• Heart problems, including heart failure. Symptoms can include abnormal heart rate or rhythm (such as feeling like your heart is beating too fast, too slow, or irregularly)
• Kidney damage. Symptoms can include urinating less often than usual
• Liver damage, including liver failure. Symptoms can include excessive or frequent bruising or bleeding

Alcohol use with Gleevec

Alcohol isn't known to interact with Gleevec. However, drinking alcohol while taking Gleevec could increase your risk for mild side effects, such as nausea, diarrhea, headache, and fatigue. This is because both alcohol and Gleevec can cause these side effects. Alcohol use with Gleevec may also increase your risk of liver damage.

Gleevec and grapefruit

Grapefruit juice is known to increase the blood levels of certain medications, including imatinib (Gleevec). This is because grapefruit juice inhibits the CYP450 isoenzyme 3A4, which decreases the metabolism of imatinib and increases imatinib concentrations in the blood. This can lead to an increased incidence of adverse reactions and side effects. Therefore, it is recommended to avoid consuming grapefruit or grapefruit juice during treatment with imatinib.

If you have been regularly consuming grapefruit or grapefruit juice while taking imatinib, it is important to consult your doctor before discontinuing the consumption of these products. This is because a sudden change in your diet may alter the effects of your medication. Similarly, if you experience any unusual or increased side effects after taking imatinib with grapefruit or grapefruit juice, be sure to inform your doctor immediately.

Although no formal studies have been conducted, it is also suggested that co-administration of Gleevec with Seville orange juice may lead to increased Gleevec plasma concentrations. Seville orange juice is not typically consumed directly due to its sour taste, but it is found in marmalades and jams. Thus, it is advisable to avoid consuming Seville orange products while taking Gleevec.

Gleevec and pregnancy

While there is no known interaction between alcohol and Gleevec, it is advised that you consult your doctor about drinking alcohol while taking the drug. This is because both alcohol and Gleevec can cause mild side effects such as nausea, diarrhoea, headaches, and fatigue. Combining the two may also increase your risk of liver damage.

Gleevec (imatinib) is categorised as a "Category D" drug by the Federal Drug Administration (FDA) in the USA with respect to pregnancy. This means that it should not be taken by women who are or could become pregnant, as it has been shown to cause harm to the foetus. There have been reports of pregnancy loss and harm to the foetus when pregnant women have taken Gleevec. Therefore, women who can become pregnant should use reliable forms of birth control while taking Gleevec and for at least 14 days after their last dose.

The prescribing information for imatinib states:

> "Gleevec can cause fetal harm when administered to a pregnant woman. Imatinib mesylate was teratogenic in rats when administered during organogenesis at doses ≥100 mg/kg (approximately equal to the maximum human dose of 800 mg/day based on body surface area). Teratogenic effects included exencephaly or encephalocele, absent/reduced frontal and absent parietal bones. Female rats administered doses ≥45 mg/kg (approximately one-half the maximum human dose of 800 mg/day based on body surface area) also experienced significant post-implantation loss as evidenced by either early fetal resorption or stillbirths, nonviable pups and early pup mortality between postpartum Days 0 and 4. At doses higher than 100 mg/kg, total fetal loss was noted in all animals. Fetal loss was not seen at doses ≤30 mg/kg (one-third the maximum human dose of 800 mg). There are no adequate and well-controlled studies with Gleevec in pregnant women. Women should be advised not to become pregnant when taking Gleevec. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus."

There have been a few case reports of outcomes of pregnancies in patients taking Gleevec. One paper describes the outcomes of 125 pregnancies, of which 63 resulted in normal births, 35 were elective terminations, 18 were spontaneous abortions, 8 were live births with abnormalities, and 1 was a stillbirth with abnormalities. Strikingly, 3 infants had similar abnormalities, including bone malformations (including skull and spine bones), kidney defects, and exomphalos (a congenital hernia). The authors hypothesised that the inhibition of platelet-derived growth factor signalling might be involved in the fetal abnormalities.

Another paper describes 8 men whose partners conceived while they were taking imatinib, resulting in 9 pregnancies. Eight babies were born healthy, and there was one spontaneous abortion.

Treating pregnant patients with Gleevec poses a challenge for doctors, as they must balance the safety of the mother and treating her cancer against the safety of the unborn child. While there is limited data available, it is recommended that imatinib not be administered to pregnant women due to its potential teratogenicity. However, in some cases, continuation of therapy with close monitoring of the pregnancy may facilitate the control of the disease and delivery of a normal infant.

Gleevec and breastfeeding

While the direct effects of consuming beer while taking Gleevec are unclear, alcohol consumption is not recommended alongside this medication. This is because both Gleevec and alcohol can cause mild side effects such as nausea, diarrhea, headache, and fatigue. Combining the two may therefore increase the risk of experiencing these side effects. Additionally, alcohol can cause liver damage, and Gleevec may also cause serious liver damage, so consuming alcohol while taking Gleevec may increase this risk.

Gleevec is not recommended for women who are breastfeeding. The drug passes into breast milk, and a breastfed infant could receive up to 10% of the maternal therapeutic dose based on body weight. This could potentially cause serious side effects in the breastfed child. Therefore, women are advised to avoid breastfeeding while taking Gleevec and for at least one month after the last dose.

If you are taking Gleevec and are considering breastfeeding, consult your doctor, who can recommend safe feeding options for your child.
