Drugs & Medications - Trezix Oral
Trezix oral Warnings
One ingredient in this product is acetaminophen. Taking too much acetaminophen may cause serious (possibly fatal) liver disease. Adults should not take more than 4000 milligrams (4 grams) of acetaminophen a day. People with liver problems and children should take less acetaminophen. Ask your doctor or pharmacist how much acetaminophen is safe to take.
Do not use with any other drug containing acetaminophen without asking your doctor or pharmacist first. Acetaminophen is in many nonprescription and prescription medications (such as pain/fever drugs or cough-and-cold products). Check the labels on all your medicines to see if they contain acetaminophen, and ask your pharmacist if you are unsure.
Get medical help right away if you take too much acetaminophen (overdose), even if you feel well. Overdose symptoms may include nausea, vomiting, loss of appetite, sweating, stomach/abdominal pain, extreme tiredness, yellowing eyes/skin, and dark urine.
Daily alcohol use, especially when combined with acetaminophen, may damage your liver. Avoid alcohol.
Children should not use products that contain dihydrocodeine after certain surgeries (including tonsil/adenoid removal). Also, for children younger than 12 years, do not use dihydrocodeine to treat cough or pain unless specifically directed by the doctor. Some children are more sensitive to dihydrocodeine and have had very serious (rarely fatal) breathing problems such as slow/shallow breathing (see also Side Effects section). Talk with your doctor or pharmacist about the risks and benefits of this medication.
Trezix oral Uses
See also Warning section.
This medication is used to treat moderate-to-severe pain. It acts on certain centers in the brain to give you pain relief. This medication is a combination of a narcotic pain reliever (dihydrocodeine), a non-aspirin pain reliever/fever reducer (acetaminophen), and caffeine. Caffeine is used to increase pain relief, especially in certain types of headaches.How to use Trezix oral
See also Warning section.
Take this medication by mouth with or without food, usually every 4 hours as needed or as directed by your doctor. If you have nausea, you may take this drug with food, although this may cause your body to absorb less of the drug and get less benefit from it. Consult your doctor or pharmacist about other ways to decrease nausea (e.g., antihistamines, lying down for 1-2 hours with as little head movement as possible).
The dosage is based on your medical condition and response to therapy. If you are taking this drug "as needed" (not on a regular schedule), remember that pain medications work best if they are used as the first signs of pain occur. If you wait until the symptoms have worsened, the medication may not work as well.
This medication may cause withdrawal reactions, especially if it has been used regularly for a long time or in high doses. In such cases, withdrawal symptoms (such as runny nose, watery eyes, anxiety, restlessness, sweating, irritability) may occur if you suddenly stop using this medication. To prevent withdrawal reactions, your doctor may reduce your dose gradually. Consult your doctor or pharmacist for more details, and report any withdrawal reactions immediately.
Though very unlikely, abnormal drug-seeking behavior (addiction) is possible with this medication. Do not increase your dose, take it more frequently, or take it for a longer time than prescribed. Properly stop the medication when so directed.
When used for an extended period, this medication may not work as well and may require different dosing. Talk with your doctor if this medication stops working well.
Inform your doctor if your pain persists or worsens.
Trezix oral Side Effects
See also Warning section.
Nausea, vomiting, constipation, diarrhea, lightheadedness, dizziness, drowsiness, headache, and trouble sleeping may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.
To prevent constipation, maintain a diet adequate in fiber, drink plenty of water, and exercise. If you become constipated while using this drug, consult your pharmacist for help in selecting a laxative (e.g., stimulant-type with stool softener).
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor right away if you have any serious side effects, including: mental/mood changes (e.g., irritability, nervousness, depression), rapid heartbeat, severe stomach/abdominal pain, change in the amount of urine.
Get medical help right away if you have any very serious side effects, including: seizures.
Dihydrocodeine is changed into a strong narcotic drug (dihydromorphine) in your body. In some people, this change happens faster and more completely than usual, which increases the risk of very serious side effects. Get medical help right away if you notice any of the following: slow/shallow breathing, unusual drowsiness/difficulty waking up, confusion.
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.
