Frequently Asked Questions
Can I take Trezix if I am pregnant?
Trezix should be avoided during pregnancy unless your doctor determines the benefits outweigh the risks. Opioid use during pregnancy can lead to withdrawal symptoms in the newborn.
What should I do if I miss a dose?
If you miss a dose, take it as soon as you remember unless it’s close to the time for your next dose. Do not double up to make up for the missed dose.
How long can I take Trezix?
Trezix is usually prescribed for short-term use due to the risk of dependency. Long-term use should be under strict medical supervision.
Can I take over-the-counter medications with Trezix?
Be cautious with over-the-counter medications, particularly those containing acetaminophen or caffeine. Always check with your healthcare provider before combining medications.
Is it safe to drive while taking Trezix?
Trezix can cause drowsiness or dizziness, so it’s important to avoid driving or operating heavy machinery until you know how the medication affects you.
Comprehensive Drug Guide
How Does Trezix Work?
- Acetaminophen reduces pain and fever by inhibiting prostaglandins, which are chemicals in the brain that cause inflammation and pain.
- Caffeine enhances the effectiveness of acetaminophen and dihydrocodeine by increasing their absorption and acting as a mild stimulant to alleviate fatigue.
- Dihydrocodeine is an opioid that binds to specific receptors in the brain and spinal cord to block pain signals, providing effective relief for moderate to moderately severe pain.
Common Dosages
- Capsules containing 320.5 mg of acetaminophen, 30 mg of caffeine, and 16 mg of dihydrocodeine.
Typical Dosing
The usual adult dosage is:
- One or two capsules every 4 hours as needed for pain. However, the total dosage should not exceed 5 capsules in a 24-hour period due to the risk of acetaminophen toxicity and the potential for opioid dependence.
Typical Dosing
FDA Approved Indications
- Moderate to moderately severe pain, especially when other pain relief options have not been effective.
Who Shouldn't Take Trezix?
- Known hypersensitivity to acetaminophen, caffeine, dihydrocodeine, or any other components of the medication.
- Significant respiratory depression or severe asthma.
- Acute or severe bronchial asthma or hypercapnia.
- Paralytic ileus or gastrointestinal obstruction.
Advice From The Pharmacist
- Take Trezix exactly as prescribed by your doctor. Do not increase the dosage or take it more frequently than directed, as it can lead to addiction or acetaminophen overdose.
- Avoid alcohol while taking Trezix, as it can increase the risk of liver damage due to acetaminophen and enhance the sedative effects of dihydrocodeine.
- If you experience any unusual symptoms such as trouble breathing, extreme drowsiness, or confusion, contact your healthcare provider immediately.
- Store Trezix in a secure location to prevent misuse or accidental ingestion, particularly by children.
