What is ConZip?

ConZip is used to treat moderate to severe pain.

The extended-release form of tramadol is for continuous treatment of severe pain and is taken on a daily schedule. This form of tramadol is not meant for use as needed.

ConZip may also be used for reasons not mentioned in this medication guide.

How should I take ConZip?

Follow the directions on your prescription label and read all medication guides or instruction sheets. Never use ConZip in larger amounts or for longer than prescribed. Tell your doctor if you feel a stronger urge to use more of ConZip.

Never share ConZip with anyone else, especially someone with a history of drug addiction. MISUSE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medicine in a place where others cannot reach it. Selling or giving away this medicine is against the law.

Do not change your dose or stop using ConZip without your doctor's advice. Ask a doctor before using any other opioid medications to treat or manage pain.

ConZip can be taken with or without food, but take it the same way each time.

Swallow the capsule or tablet whole to avoid the risk of a potentially fatal overdose. Do not crush, chew, break, open, or dissolve.

Measure liquid medicine using the supplied measuring device (not a kitchen spoon).

Never crush or break a ConZip pill to inhale the powder or mix it into a liquid to inject into your vein. This practice has resulted in death.

You may experience withdrawal symptoms if you stop using ConZip suddenly. Ask your doctor before stopping the medicine.

Store at room temperature away from moisture and heat. Keep your medicine in a place where no one can use it improperly.

Do not keep leftover medicine. Just one dose can cause death in someone using it accidentally or improperly. Ask your pharmacist about a drug take-back program. You may also mix the leftover medicine with cat litter or coffee grounds in a sealed plastic bag and throw the bag in the trash.

ConZip side effects

Get emergency medical help if you have signs of an allergic reaction (hives, difficulty breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling).

ConZip can slow or stop your breathing, and death may occur, especially if you drink alcohol or use other drugs that cause drowsiness or slow breathing. A person caring for you should give naloxone and/or seek emergency medical attention if you have slow breathing with long pauses, blue-colored lips, or if you are hard to wake up.

ConZip may cause serious side effects. Call your doctor right away if you have:

  • headache, hunger, weakness, sweating, irritability, dizziness, fast heart rate, or feeling jittery;
  • increased sensitivity to pain or if your pain gets worse;
  • seizure (convulsions), confusion, problems with thinking or memory, weakness, feeling unsteady;
  • noisy breathing, sighing, shallow breathing, breathing that stops during sleep, a slow heart rate or weak pulse, a light-headed feeling, like you might pass out; or
  • low cortisol levels—nausea, vomiting, loss of appetite, dizziness, worsening tiredness or weakness.

Serious breathing problems may be more likely in older adults and people who are weak or have wasting syndrome or chronic breathing disorders.

Seek medical attention right away if you have symptoms of serotonin syndrome, such as: agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, or diarrhea.

Common side effects of ConZip may include:

  • itching, constipation, nausea, vomiting, stomach pain; or
  • dizziness, drowsiness, tiredness, headache.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

What happens if I miss a dose?

Since ConZip is used for pain, you are unlikely to miss a dose. If you do miss a dose and it is close to the time for your next dose, skip the missed dose. Do not take two doses at the same time.

This section was rewritten for readability and reviewed for meaning.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose can be fatal, especially in a child or anyone using ConZip without a prescription. Overdose symptoms may include severe drowsiness, pinpoint pupils, slow breathing, or no breathing.

Your doctor may recommend that you get naloxone (a medicine to reverse an opioid overdose) and keep it with you at all times. A person caring for you can give the naloxone if you stop breathing or do not wake up. Your caregiver must still get emergency medical help and may need to perform CPR (cardiopulmonary resuscitation) on you while waiting for help to arrive.

Anyone can buy naloxone from a pharmacy or local health department. Make sure that anyone caring for you knows where you keep naloxone and how to use it.

Do not drink alcohol or any products that contain alcohol. Dangerous side effects or death could occur.

Avoid driving or doing risky activities until you know how this medicine will affect you. Dizziness or drowsiness can lead to falls, accidents, or severe injuries. Also avoid getting up too quickly from a sitting or lying position, or you may feel dizzy.

What other drugs will affect ConZip?

You may have breathing problems or withdrawal symptoms if you start or stop taking certain other medicines. Tell your doctor if you also use an antibiotic, antifungal medication, heart or blood pressure medication, seizure medication, or medicine to treat HIV or hepatitis C.

Many other drugs can be dangerous when used with ConZip. Tell your doctor if you also use:

  • medicine for allergies, asthma, blood pressure, motion sickness, irritable bowel, or overactive bladder;
  • a benzodiazepine sedative like Valium, Klonopin, or Xanax;
  • other opioid medicines, sleep medicine, muscle relaxers, or other drugs that make you drowsy; or
  • drugs that affect serotonin, such as antidepressants, stimulants, or medicine for migraines or Parkinson's disease.

Common questions about ConZip

Can you take ibuprofen 800 mg with tramadol 50 mg?
Yes, you can take these medications together. Tramadol is safe to take with ibuprofen and may be used to provide additional pain relief. But be aware 800mg ibuprofen is a high dose of ibuprofen that may cause gastrointestinal side effects such as abdominal pain or reflux if taken long term. Continue reading
Which drugs cause opioid-induced constipation?
Any drug that is classified as an "opioid" can cause constipation, which can be a serious side effect if not addressed. Examples of commonly prescribed opioids that may cause this side effect include morphine, tramadol, fentanyl, methadone, hydrocodone, codeine and oxycodone. Continue reading
Is tramadol an opioid?
Tramadol is an opioid (narcotic) analgesic that also has non-opioid effects. It is classified as a Schedule IV controlled substance due to its moderate potential for misuse and addiction, although this is less than that of traditional opioids. Tramadol is approved for the relief of moderate to moderately severe chronic pain in adults, when other pain treatments such as non-opioid pain medicines do not treat pain well enough, or are not tolerated. Continue reading
How do genetics affect tramadol?
Pain-relieving and side effects of tramadol are greatly affected by a person’s genetics, particularly their capacity for tramadol metabolism through a liver enzyme system called cytochrome P450 2D6. Continue reading
Can You Take Tramadol with Acetaminophen, Ibuprofen, or Aspirin?
Yes, for most people, tramadol can be safely combined with acetaminophen, ibuprofen, or aspirin, and doing so can provide better pain relief than either medicine alone. However, there are important age restrictions and clinical considerations to be aware of. Continue reading
How much tramadol should I give my dog?
How much tramadol you give your dog depends on the size of your dog. Smaller dogs do not need as much tramadol as larger dogs need to relieve pain. If you give too much tramadol your dog is likely to have more severe side effects. The tramadol dosage for dogs is usually between 0.45 to 1.8 mg per pound of body weight (1mg to 4 mg/kg). The frequency varies depending on what you are giving it for. For general pain, it is given every 8 to 12 hours, but for cancer-related pain, it can be administered every 6 hours. Continue reading
How long does it take for tramadol to start working?
Tramadol generally starts to relieve pain within an hour in its fast-acting forms, which are used for short-term pain management. With slow-release or extended-release (ER) forms, the drug may take longer to start because it’s gradually released over 12 or 24 hours, but pain relief lasts longer. Continue reading
How long does tramadol withdrawal last?
Symptoms of tramadol withdrawal can start 8-24 hours after the last dose. Untreated, withdrawal symptoms usually last for 4-10 days. Withdrawal is caused by stopping the drug suddenly. Continue reading
Is tramadol stronger than codeine?
Both tramadol and codeine are prescription painkillers used to treat moderate pain, and they are generally considered comparable in terms of pain relief. Tramadol is sometimes considered slightly more effective for moderate to moderately severe pain due to its dual mechanism of action, but both are classified as "weak" opioids. Continue reading
