Lortab Elixir During Pregnancy or Breastfeeding
There are no well-controlled studies on the use of this drug in pregnant women. Lortab Elixir should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Babies born to mothers who have been taking opioids regularly prior to delivery will be physically dependent. Acetaminophen is excreted in human milk in small amounts. It is not known whether hydrocodone is excreted in human milk. A decision should be made whether to discontinue nursing or to discontinue the drug in breastfeeding women. Like all narcotic pain relievers, Lortab elixir may cause dependence and withdrawal reactions, especially if it has been used regularly for a long time or in high doses.

Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
Opioid medicine can slow or stop your breathing, and death may occur. 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.
In rare cases, acetaminophen may cause a severe skin reaction that can be fatal. This could occur even if you have taken acetaminophen in the past and had no reaction. Stop taking this medicine and call your doctor right away if you have skin redness or a rash that spreads and causes blistering and peeling.
Call your doctor at once if you have:
- noisy breathing, sighing, shallow breathing, breathing that stops;
- a light-headed feeling, like you might pass out;
- liver problems--nausea, upper stomach pain, tiredness, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes);
- low cortisol levels-- nausea, vomiting, loss of appetite, dizziness, worsening tiredness or weakness; o
- high levels of serotonin in the body--agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, diarrhea.
Serious breathing problems may be more likely in older adults and in those who are debilitated or have wasting syndrome or chronic breathing disorders.

DRUG ABUSE AND DEPENDENCE
Controlled Substance
Lortab Elixir (hydrocodone bitartrate and acetaminophen oral solution) (hydrocodone bitartrate and acetaminophen oral solution) is classified as a Schedule III controlled substance.
Abuse and Dependence
Hydrocodone can produce drug dependence of the morphine type and, therefore, has the potential for being abused. Psychological dependence, physical dependence, and tolerance may develop upon repeated administration of narcotics; therefore, this product should be prescribed and administered with caution appropriate to the use of other oral narcotic medications. However, psychological dependence is unlikely to develop when hydrocodone bitartrate and acetaminophen oral solution are used for a short time for the treatment of pain.
Physical dependence, the condition in which continued administration of the drug is required to prevent the appearance of a withdrawal syndrome, assumes clinically significant proportions only after several weeks of continued narcotic use, although some mild degree of physical dependence may develop after a few days of narcotic therapy. Tolerance, in which increasingly large doses are required in order to produce the same degree of analgesia, is manifested initially by a shortened duration of analgesic effect, and subsequently by decreases in the intensity of analgesia. The rate of development of tolerance varies among patients.
