What should I watch for?
Tell your doctor or healthcare professional if your symptoms do not start to get better or if they get worse.
Do not stop taking except on your doctor's advice. You may develop a severe reaction. Your doctor will tell you how much medicine to take.
If you are also taking a narcotic medicine for pain or cough or another medicine that also causes drowsiness, you may have more side effects. Give your health care provider a list of all medicines you use. Your doctor will tell you how much medicine to take. Do not take more medicine than directed. Call emergency for help if you have problems breathing or unusual sleepiness.
You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medicine affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol may interfere with the effect of this medicine. Avoid alcoholic drinks.
Wear a medical ID bracelet or chain, and carry a card that describes your disease and details of your medicine and dosage regimens.
This medicine may cause constipation. Try to have a bowel movement at least every 2 to 3 days. If you do not have a bowel movement for 3 days, call your doctor or health care professional.
Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water may help. Contact your doctor if the problem does not go away or is severe.
The implants may be difficult to locate if they are inserted too deeply, if you move them, or if you gain a lot of weight after they are inserted. Special tests or procedures may be needed in these instances to locate the implants for removal.
If an implant sticks out or comes out of your skin, wash your hands if you touch the implant. Cover the area where the implant was inserted with a clean bandage. Put the implant in a plastic bag and in a safe place out of reach of children and theft. Do not let others touch or use the implant. If a child puts an implant in his/her mouth, get emergency help right away. Return the implant to your healthcare provider as soon as possible. Never give your medicine to others, because it may cause serious harm, including death. Selling or giving away your medicine is against the law.
If the implants come out of your arm or if you stop treatment, you can have symptoms of opiate withdrawal including: shaking, sweating more than normal, feeling hot or cold more than normal, runny nose, watery eyes, goose bumps, diarrhea, vomiting, and muscle aches. Tell your healthcare provider if you develop any of these symptoms.
In an emergency, have a family member or friend tell the emergency room staff that you are physically dependent on an opiate and are being treated with an opiate implant.
