Lofexidine is used to decrease withdrawal symptoms caused by stopping opioids.
How to use Lucemyra
Read the Patient Information Leaflet if available from your pharmacist before you start taking lofexidine and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
The dosage is based on your medical condition and response to treatment. Your doctor will adjust the dose based on withdrawal symptoms. Do not increase your dose or use this drug more often or for longer than prescribed. Your condition will not improve any faster, and your risk of side effects will increase.
Use this medication regularly to get the most benefit from it. To help you remember, use it at the same times each day.
If you suddenly stop using this medication, you may have high blood pressure or withdrawal symptoms (such as diarrhea, trouble sleeping, anxiety, chills, sweating, muscle aches). To help prevent withdrawal, your doctor may lower your dose slowly. Tell your doctor or pharmacist right away if you have withdrawal.
To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor right away if you have any serious side effects, including: ringing in the ears.
Get medical help right away if you have any very serious side effects, including: fainting, fast/irregular heartbeat, severe dizziness.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

Before taking lofexidine, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Before using this medication, tell your doctor or pharmacist your medical history, especially of: liver disease, kidney disease, high or low blood pressure, heart disease (such as coronary artery disease), stroke.
This drug may make you dizzy or drowsy. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Avoid alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).
Lofexidine may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.
The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using lofexidine, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).
Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using lofexidine safely.
Too much sweating, diarrhea, or vomiting may cause loss of too much body water (dehydration) and increase your risk of lightheadedness. Report prolonged diarrhea or vomiting to your doctor. Be sure to drink enough fluids to prevent dehydration unless your doctor directs you otherwise.
Older adults may be more sensitive to the side effects of this drug, especially QT prolongation (see above).
During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.
It is unknown if lofexidine passes into breast milk. Consult your doctor before breast-feeding.
