ULTRAM

How Does Ultram Work?
Ultram is classified as a "centrally acting opioid analgesic. " This means that it works in the central nervous system (the brain and spinal cord), acts much like morphine in the body, and relieves pain. Much like morphine, Ultram binds to certain opioid receptors in the body known as μ ("mu") receptors.

Ultram also works in a similar manner as some antidepressant medications, by inhibiting the reuptake of certain brain chemicals (serotonin and norepinephrine). Serotonin and norepinephrine are two of several chemicals used to send messages from one nerve cell to another. As a message travels down a nerve, it causes the end of the cell to release serotonin or norepinephrine. The serotonin or norepinephrine enters the gap between the first nerve cell and the one next to it. When enough reaches the second nerve cell, it activates receptors on the cell and the message continues on its way. The first cell then quickly absorbs any serotonin or norepinephrine that remains in the gap between cells. This is called "reuptake."

You should not take tramadol if you have ever been addicted to drugs or alcohol.

Seizures (convulsions) have occurred in some people taking tramadol. You may be more likely to have a seizure while taking tramadol if you have a history of seizures or head injury, a metabolic disorder, or if you are taking certain medicines such as antidepressants, muscle relaxers, or medicine for nausea and vomiting.

Take tramadol exactly as it was prescribed for you. Do not take it in larger doses or for longer than recommended by your doctor. Do not take more than 300 milligrams of tramadol in one day.

Seek emergency medical attention if you think you have used too much of this medicine. A tramadol overdose can be fatal. Overdose symptoms of a tramadol overdose may include drowsiness, shallow breathing, slow heartbeat, extreme weakness, cold or clammy skin, feeling light-headed, fainting, or coma.

Tramadol may be habit-forming and should be used only by the person it was prescribed for. Tramadol should never be given to another person, especially someone who has a history of drug abuse or addiction. Keep the medication in a secure place where others cannot get to it.

Tramadol can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval. Some products that may interact with this drug include: certain pain medications (mixed narcotic agonist-antagonists such as pentazocine, nalbuphine, butorphanol), narcotic antagonists (such as naltrexone). Avoid taking MAO inhibitors (isocarboxazid, linezolid, moclobemide, phenelzine, procarbazine, rasagiline, selegiline, tranylcypromine) within 2 weeks before and during treatment with this medication. In some cases a serious (possibly fatal) drug interaction may occur.Before using tramadol, report the use of other drugs that increase serotonin, such as dextromethorphan, lithium, St. John's wort, sibutramine, street drugs such as MDMA/"ecstasy," tryptophan, certain antidepressants including SSRIs (such as citalopram, paroxetine) and SNRIs (such as duloxetine, venlafaxine), "triptans" used to treat migraine headaches (such as eletriptan, sumatriptan), among others. The risk of serotonin syndrome may be more likely when you start or increase the dose of these medications.Other medications can affect the removal of tramadol from your body, which may affect how tramadol works. Examples include quinidine, azole antifungals (such as itraconazole), HIV drugs (such as ritonavir), macrolide antibiotics (such as erythromycin), rifamycins (such as rifampin), drugs used to treat seizures (such as carbamazepine), among others.

The risk of serious side effects (such as slow/shallow breathing, severe drowsiness) may be increased if this medication is taken with other products that may also affect breathing or cause drowsiness. Therefore, tell your doctor or pharmacist if you are taking other products such as alcohol, allergy or cough-and-cold products, medicine for sleep or anxiety (such as alprazolam, diazepam, zolpidem), muscle relaxants, other narcotic pain relievers (such as morphine), and psychiatric medicines (such as risperidone, amitriptyline, trazodone). Your medications or doses of your medications may need to be changed.

What other drugs will affect Ultram?
You may be more likely to have a seizure (convulsions) if you take Ultram while you are using certain other medicines. Do not take Ultram without telling your doctor if you also use any of the following medications:

• an MAO inhibitor such as isocarboxazid (Marplan), tranylcypromine (Parnate), phenelzine (Nardil), or selegiline (Eldepryl, Emsam); or
• an antidepressant such as amitriptyline (Elavil, Vanatrip), citalopram (Celexa), clomipramine (Anafranil), desipramine (Norpramin), escitalopram (Lexapro), fluoxetine (Prozac, Sarafem), fluvoxamine (Luvox), imipramine (Tofranil), nortriptyline (Pamelor), paroxetine (Paxil), or sertraline (Zoloft).

Cold or allergy medicine, sleeping pills, muscle relaxers, and medicine for seizures or anxiety can add to sleepiness caused by Ultram. Tell your doctor if you regularly use any of these medicines, or any other pain medication.

Tell your doctor about all other medicines you use, especially:

• carbamazepine (Tegretol);
• lithium (Eskalith, LithoBid);
• ADHD medications (Adderall, Ritalin, Strattera);
• an antibiotic such as clarithromycin (Biaxin), erythromycin (E.E.S., EryPed, Ery-Tab, Erythrocin), linezolid (Zyvox), rifampin (Rifadin, Rimactane, Rifater); or telithromycin (Ketek);
• antifungal medication such as clotrimazole (Mycelex Troche), itraconazole (Sporanox), ketoconazole (Extina, Ketozole, Nizoral, Xolegal), or voriconazole (Vfend);
• cancer medications such as gefitinib (Iressa), imatinib (Gleevec), or nilotinib (Tasigna);
• a heart rhythm medication such as amiodarone (Cordarone, Pacerone), flecainide (Tambocor), propafenone (Rythmol), or quinidine (Quin-G);
• heart or blood pressure medication such as diltiazem (Cartia, Cardizem), felodipine (Plendil), nifedipine (Nifedical, Procardia), verapamil (Calan, Covera, Isoptin, Verelan), and others;
• HIV/AIDS medicine such as atazanavir (Reyataz), delavirdine (Rescriptor), fosamprenavir (Lexiva), indinavir (Crixivan), nelfinavir (Viracept), saquinavir (Invirase), or ritonavir (Norvir, Kaletra); or
• migraine headache medicine such as sumatriptan (Imitrex, Treximet).

This list is not complete and there are many other drugs that can interact with Ultram. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor. Keep a list of all your medicines and show it to any healthcare provider who treats you.
