Warnings:

Codeine has a risk for abuse and addiction, which can lead to overdose and death. Codeine may also cause severe, possibly fatal, breathing problems. To lower your risk, your doctor should have you use the smallest dose of codeine that works, and use it for the shortest possible time. See also How to Use section for more information about addiction.

The risk for severe breathing problems is higher when you start this medication and after a dose increase, or if you use the wrong dose/strength. Using this medication with alcohol or other drugs that can cause drowsiness or breathing problems may cause very serious side effects, including death. Also, other medications can affect the removal of codeine from your body, which may affect how codeine works. Be sure you know how to use codeine and what other drugs you should avoid using with it. See also Drug Interactions section. Get medical help right away if any of these very serious side effects occur: slow/shallow breathing, unusual lightheadedness, severe drowsiness/dizziness, difficulty waking up.

Keep this medicine in a safe place to prevent theft, misuse, or abuse. If someone accidentally uses this drug, get medical help right away.

Before using this medication, women of childbearing age should talk with their doctor(s) about the risks and benefits. Tell your doctor if you are pregnant or if you plan to become pregnant. During pregnancy, this medication should be used only when clearly needed. It may slightly increase the risk of birth defects if used during the first two months of pregnancy. Also, using it for a long time or in high doses near the expected delivery date may harm the unborn baby. To lessen the risk, use the smallest effective dose for the shortest possible time. Babies born to mothers who use this drug for a long time may develop severe (possibly fatal) withdrawal symptoms. Tell the doctor right away if you notice any symptoms in your newborn baby such as crying that doesn't stop, slow/shallow breathing, irritability, shaking, vomiting, diarrhea, poor feeding, or difficulty gaining weight.

Children younger than 18 years should not use products that contain codeine. Some children are more sensitive to codeine and have had very serious (rarely fatal) breathing problems such as slow/shallow breathing (see also Side Effects section). The risk is greater in children who are obese or have breathing problems, or after certain surgeries (including tonsil/adenoid removal). Talk with your doctor or pharmacist about the risks and benefits of this medication.

How to use Codeine Phosphate Syringe

This medication is given by injection into a muscle or under the skin as directed by your doctor. Learn the proper way to give injections. If you have any questions about the use of this medication, consult your doctor or pharmacist.

Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Before injecting each dose, clean the injection site with rubbing alcohol. It is important to change the location of the injection site with each dose to avoid problem areas under the skin.

The dosage is based on your medical condition and response to treatment. Pain medications work best if they are used as the first signs of pain occur. If you wait until the pain has worsened, the medication may not work as well. Do not increase your dose, use the medication more often, or use it for a longer time than prescribed. Properly stop the medication when so directed.

If you have nausea, ask your doctor or pharmacist about ways to decrease it (such as lying down for 1 to 2 hours with as little head movement as possible).

If you have ongoing pain (such as due to cancer), your doctor may direct you to also take long-acting opioid medications. In that case, this medication might be used for sudden (breakthrough) pain only as needed. Other pain relievers (such as acetaminophen, ibuprofen) may also be prescribed. Ask your doctor or pharmacist about using codeine safely with other drugs.

Suddenly stopping this medication may cause withdrawal, especially if you have used it for a long time or in high doses. To prevent withdrawal, your doctor may lower your dose slowly. Tell your doctor or pharmacist right away if you have any withdrawal symptoms such as restlessness, mental/mood changes (including anxiety, trouble sleeping, thoughts of suicide), watering eyes, runny nose, nausea, diarrhea, sweating, muscle aches, or sudden changes in behavior.

When this medication is used for a long time, it may not work as well. Talk with your doctor if this medication stops working well.
