Don't drive a car or operate machinery until you know how Lucemyra (lofexidine) affects you. This medication can make you sleepy, which can potentially lead to accidents if you're not careful.
Avoid drinking alcohol while you're taking Lucemyra (lofexidine) since this combination can lead to excessive sleepiness.
Lucemyra (lofexidine) can lower your blood pressure or slow down your heart rate, which can cause dizziness and lightheadedness. Get up slowly from a sitting or lying down position after you take the medication so you don't feel dizzy or fall. Tell your provider if you faint or feel dizzy while you're taking this medication.

What are the risks and warnings for Lucemyra (lofexidine)?
Lucemyra (lofexidine) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Low blood pressure, slow heart rate, and fainting
Risk factors: Dehydration | Overheating | History of heart problems, slow heart rate, or recent heart attack | History of stroke | Kidney failure | Taking medications that lower blood pressure or heart rate
Lucemyra (lofexidine) can lower your blood pressure and heart rate, which can put you at risk of fainting. Some medical conditions and medications can raise your risk for these side effects. Tell your providers about your medical history and all your medications so they can decide whether Lucemyra (lofexidine) is safe for you to take.
While you're taking Lucemyra (lofexidine), it's important that you watch out for symptoms of dizziness, lightheadedness, and feeling faint when you change positions too quickly. Tell your provider right away if you have these symptoms so your provider can adjust your dose as needed. Skip your scheduled dose of Lucemyra (lofexidine) if your symptoms haven't gone away and you can't reach your provider.
Get up slowly from a sitting or lying down position to prevent a sudden drop in blood pressure. During treatment, stay cool and drink plenty of fluids since dehydration and overheating can lower your blood pressure as well.
Life-threatening abnormal heart rhythm
Risk factors: Heart failure | Slow heart rhythm | Kidney problems | Liver problems | Low magnesium or potassium levels | Taking medications that can cause abnormal heart rhythm (e.g., methadone (Methadose))
Lucemyra (lofexidine) can affect your heart rhythm because it can affect how long it takes for the heart to pump and then relax. This is known as QT prolongation or long QT syndrome. Abnormal heart rhythms caused by this problem can be serious and life-threatening.
Tell your providers about your medical history and all the medications you take so they can check for your risk for QT prolongation. It's typically higher if you have certain factors, like abnormal electrolyte levels and heart rhythm problems. Your risk is also higher if you're taking other medications that cause heart rhythm problems, such as methadone (Methadose).
Your provider might check your heart and perform electrocardiograms (EKGs) to make sure your heart rhythm is normal. Call 911 right away if you feel your chest pounding, have shortness of breath, have chest pain, or feel faint or lightheaded while you're taking Lucemyra (lofexidine).
Excessive sleepiness
Risk factors: Taking benzodiazepines, barbiturates, or other medications that cause drowsiness | Taking other medications that can slow your body down | Drinking alcohol
Lucemyra (lofexidine) can make you feel very sleepy and can affect your ability to think. The risk is higher if you drink alcohol or if you take medications that make you drowsy or slow your body down, such as benzodiazepines and sleep medications. Don't drive a car or operate machinery right after you take Lucemyra (lofexidine) and until you know how the medication affects you. Get medical attention right away if you have symptoms such as slurred speech, lightheadedness, confusion, dizziness, or excessive drowsiness.
Higher risk of opioid overdose
Risk factor: Opioid use disorder
Lucemyra (lofexidine) is only used to relieve opioid withdrawal symptoms after you've suddenly stopped taking an opioid medication. It's not approved for treating opioid use disorder (opioid addiction).
Once you've completed a treatment plan to stop using an opioid, you can become more sensitive to opioids. This can lead to a higher risk of a fatal overdose if you restart an opioid medication. Work closely with your provider to manage your opioid withdrawal symptoms. Get medical help right away if your family or friend notices you have slow and shallow breathing; this can be a sign of an overdose.
Withdrawal side effects
Suddenly stopping Lucemyra (lofexidine) can make your blood pressure go up, which can be dangerous. People have also had other symptoms, such as trouble sleeping, anxiety, chills, excessive sweating, and pain in the arms and legs, after they stopped taking this medication. Talk with your provider if you want to stop Lucemyra (lofexidine). Your provider can help you safely stop this medication by lowering your dose slowly over time.
