            Pregnancy & Lactation

            Pregnancy

            Based on mechanism of action and findings from animal studies, therapy can cause fetal harm when administered to a pregnant woman

            There are insufficient data in pregnant women to inform a drug-associated risk of major birth defects and miscarriage

            Advise pregnant women of potential risk to fetus

            Animal data

            • In animal reproduction studies, administration of drug to pregnant rats and rabbits during period of organogenesis caused adverse developmental outcomes at maternal exposures approximately 0.5 times the human exposure based on AUC0-24 hours

            Reproductive potential

            • Can cause fetal harm when administered to a pregnant woman

            Pregnancy testing

            • Perform pregnancy testing in females of reproductive potential within 7 days prior to initiating therapy

            Contraception

            • Females: Advise patients of reproductive potential to use effective contraception during treatment and for at least 6 months after the last dose
            • Males: Advise males with female partners of reproductive potential to use effective contraception and to avoid fathering a child during treatment with ZOLINZA and for at least 3 months after the last dose

            Infertility

            • Based on findings in animals, therapy has the potential to affect female fertility

            Lactation

            There are no data on presence of drug or its metabolites in human milk, effects on a breastfed child, or on milk production; because many drugs are excreted in human milk and because of potential for serious adverse drug reactions in a nursing child, advise lactating women not to breastfeed during treatment and for at least 1 week after last dose

            Pregnancy Categories

            A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

            B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

            C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

            NA: Information not available.

To prevent dehydration while taking this medication, drink at least 8 glasses of water (8 ounces/240 milliliters each) throughout the day unless your doctor directs you otherwise.Do not use capsules that are opened or crushed. If your skin or eyes come in contact with the powder inside the capsule, wash the area well with plenty of water and call your doctor.The dosage is based on your medical condition and response to treatment. Do not increase your dose or take this medication more often than prescribed. Your condition will not improve any faster, and the risk of serious side effects may be increased.Since this drug can be absorbed through the skin and lungs, women who are pregnant or who may become pregnant should not handle this medication or breathe the dust from the capsules.Tell your doctor if your condition does not improve or if it worsens.

            SIDE EFFECTS: Tiredness, loss of appetite, weight loss, dizziness, dry mouth, change in the sense of taste, hair loss, headache, or cough may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.Nausea, vomiting, and diarrhea can also occur and may be severe. Tell your doctor right away if these effects occur. In some cases, your doctor may prescribe medication to prevent or relieve them. Eating several small meals, not eating before treatment, or limiting activity may help to lessen the nausea and vomiting.People using this medication may have serious side effects. However, you have been prescribed this drug because your doctor has judged that the benefit to you is greater than the risk of side effects. Careful monitoring by your doctor may decrease your risk.Vomiting/diarrhea that doesn't stop may result in dehydration. Contact your doctor promptly if you notice any symptoms of dehydration, such as unusual decreased urination, unusual dry mouth/thirst, fast heartbeat, or dizziness/lightheadedness.This medication may rarely make your blood sugar rise, which can cause or worsen diabetes. Tell your doctor right away if you have symptoms of high blood sugar such as increased thirst/urination. If you already have diabetes, check your blood sugar regularly as directed and share the results with your doctor. Your doctor may need to adjust your diabetes medication, exercise program, or diet.This medication decreases bone marrow function, an effect that may lead to a low number of blood cells such as red cells, white cells, and platelets. This effect can cause anemia, decrease your body's ability to fight an infection, or cause easy bruising/bleeding. You may be at an increased risk for stomach/intestine bleeding if you are taking certain medications (see also Drug Interaction section). Tell your doctor right away if you develop any of the following unlikely symptoms: unusual tiredness, pale skin, signs of infection (such as sore throat that doesn't go away, fever, chills), easy bruising/bleeding, signs of stomach/intestine bleeding (such as black/bloody stools, vomit that contains blood or looks like coffee grounds, dizziness).Tell your doctor right away if you have any serious side effects, including: signs of low levels of magnesium/potassium/calcium in the blood (such as severe muscle spasms/cramps, irregular heartbeat, mental/mood changes, seizures).This medication may rarely cause blood clots (such as pulmonary embolism and deep vein thrombosis). You may be at increased risk for blood clots if you have a history of blood clots. Get medical help right away if any of these side effects occur: chest pain, pain/redness/swelling usually in the leg, trouble breathing.Get medical help right away if you have any very serious side effects, including: fast/irregular heartbeat, severe dizziness, fainting.A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects.

Talk to your pharmacist for more details.Before using this medication, tell your doctor or pharmacist your medical history, especially of: liver disease, certain mineral imbalances (such as low levels of potassium or magnesium in the blood), blood clots.This drug may make you dizzy. Alcohol or marijuana (cannabis) can make you more dizzy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).Vorinostat may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using vorinostat, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using vorinostat safely.Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).Older adults may be more sensitive to the side effects of this drug, especially QT prolongation.Tell your doctor if you are pregnant or plan to become pregnant. You should not become pregnant while using vorinostat. Vorinostat may harm an unborn baby. Your doctor should order a pregnancy test before you start this medication. Women using this medication should ask about reliable forms of birth control during treatment and for at least 6 months after the last dose.
