Precautions while using Luvox CR
It is very important for your doctor to check your progress at regular visits. This will help adjust the dose and reduce any side effects. Blood tests may be needed to check for unwanted effects.
Do not take alosetron (Lotronex®), pimozide (Orap®), ramelteon (Rozerem®), thioridazine (Mellaril®), or tizanidine (Zanaflex®) while you are taking fluvoxamine. Using these medicines together could lead to more side effects than usual.
Do not take fluvoxamine with a monoamine oxidase (MAO) inhibitor (for example, isocarboxazid [Marplan®], linezolid [Zyvox®], methylene blue injection, phenelzine [Nardil®], selegiline [Eldepryl®], tranylcypromine [Parnate®]). Do not start fluvoxamine within 2 weeks after stopping a MAO inhibitor and wait 2 weeks after stopping fluvoxamine before starting a MAO inhibitor. Taking them together or not waiting 2 weeks may cause confusion, agitation, restlessness, stomach or intestinal symptoms, a sudden high body temperature, extremely high blood pressure, or severe seizures.
Fluvoxamine may cause a serious condition called serotonin syndrome if taken with certain medicines. Do not use fluvoxamine with buspirone (Buspar®), fentanyl (Abstral®, Duragesic®), lithium (Eskalith®, Lithobid®), tryptophan, St. John's wort, amphetamines, or certain pain or migraine medicines (such as meperidine, methadone, rizatriptan, sumatriptan, tramadol, Demerol®, Methadose®, Frova®, Imitrex®, Maxalt®, Relpax®, Ultram®, Zomig®). Always check with your doctor before taking any other medicines with fluvoxamine.
Fluvoxamine may cause some people to feel agitated, irritable, or show other unusual behaviors. It may also lead some children, teenagers, and young adults to have suicidal thoughts or to feel more depressed. Some people may have trouble sleeping, become easily upset, experience a large increase in energy, or act recklessly. If you or your caregiver notice any of these side effects, tell your doctor right away. Inform your doctor if you or anyone in your family has bipolar disorder (manic-depressive) or has attempted suicide.
Avoid drinking alcohol while taking fluvoxamine.
This medicine may cause some people to feel drowsy, think less clearly, or experience blurred vision or poor muscle control. Make sure you understand how you react to this medicine before driving, using machines, or doing anything else that could be dangerous if you are not alert or able to see clearly.
Do not suddenly stop taking this medicine without consulting your doctor first. Your doctor may want you to gradually lower your dose before stopping it completely. This helps reduce the chance of withdrawal symptoms like agitation, confusion, headache, irritability, numbness or tingling, restlessness, trouble sleeping, or unusual drowsiness or weakness.
This medicine may raise your risk of bleeding problems. Make sure your doctor knows if you are taking other medicines that thin the blood, including aspirin, NSAIDs (such as diclofenac, ibuprofen, naproxen, Advil®, Aleve®, Celebrex®, Voltaren®), or warfarin (Coumadin®, Jantoven®).
Hyponatremia (low sodium in the blood) may occur with this medicine. Contact your doctor immediately if you experience confusion, difficulty concentrating, headaches, memory issues, weakness, or unsteadiness.
Tell your doctor right away if you develop a rash or hives, swelling of the face, eyes, or mouth, or trouble breathing after taking this medicine.
Check with your doctor immediately if you experience decreased interest in sexual intercourse, delayed or inability to have an orgasm in women, inability to have or maintain an erection in men, or loss in sexual ability, desire, drive, or performance. These may be signs of sexual dysfunction.
Some men and women using this medicine have become infertile (unable to have children). Discuss this with your doctor before using this medicine if you plan to have children.
Do not take other medicines unless your doctor has discussed them with you. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (like St. John's wort) or vitamin supplements.

Before using Luvox CR
In deciding to use a medicine, the chances of taking the medicine must be weighed against the good it will do. This is a decision you and your clinician will make. For this medication, the following should be considered:
Allergies
Inform your clinician if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Pediatric
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of fluvoxamine tablets in children 8 to 17 years of age. Since fluvoxamine may cause weight loss or a lower in appetite, children who will be using fluvoxamine for a long time should have their weight and growth measured by the doctor regularly.
Appropriate studies have not been performed on the relationship of age to the effects of fluvoxamine extended-release capsules in the pediatric population. Safety and efficacy have not been established.
Geriatric
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of fluvoxamine in the elderly. Nevertheless, elderly patients are more likely to have hyponatremia (low sodium in the blood) and age-related liver issues, which may require an adjustment in the dose for patients receiving fluvoxamine.
Breast Feeding
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks prior to using this drug while breastfeeding.

Although certain medications should not be used together at all, in other cases two different drugs may be used together even if an interaction might occur. In these cases, your clinician may want to change the dose, or other precautions may be necessary. When you are using this medication, it is especially important that your healthcare professional know if you are using any of the medications listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.
