  • Storage instructions...Tablets and liquid should be stored at room temperature. Protect from light and extreme cold or heat. Suppositories should be stored in the refrigerator.

Why should Hydromorphone hydrochloride not be prescribed?

Special warnings about Hydromorphone hydrochloride

Do not stop taking Hydromorphone hydrochloride without your doctor's approval. Abruptly stopping Dilaudid could cause withdrawal symptoms within the first 24 hours, including restlessness, tearing or watery eyes, dilated pupils, runny nose, yawning, sweating, goosebumps, and restless sleep. These symptoms could increase during the next 72 hours, and new withdrawal symptoms may appear, including irritability, anxiety, weakness, muscle spasms, severe backache, stomach or leg pain, insomnia, vomiting, and diarrhea.

Dilaudid may impair the mental and/or physical abilities required for the performance of potentially hazardous tasks such as driving a car or operating machinery.

Dilaudid should be used with caution if you are in a weakened condition or if you have a severe liver or kidney disorder, hypothyroidism (underactive thyroid gland), Addison's disease (adrenal gland failure), severe lung problems, an enlarged prostate, a urethral stricture (narrowing of the urethra), low blood pressure, or a head injury.

It's important to tell the doctor if you've ever suffered from alcoholism or other drug dependencies. Abusing Dilaudid, or combining it with other nervous system depressants, can cause serious—and possibly life-threatening—side effects.

Dilaudid suppresses the cough reflex; therefore, the doctor will be cautious about prescribing Dilaudid after an operation or for patients with a lung disease.

High doses of Dilaudid may produce labored or slowed breathing. This drug also affects centers that control breathing rhythm and may produce irregular breathing. People who already have breathing difficulties should be very careful about taking Dilaudid. Be especially cautious if you have chronic obstructive pulmonary disease or a condition that reduces oxygen to the tissues (hypoxia) or causes an excess of carbon dioxide in the blood (hypercapnia).

Let the doctor know if you're scheduled to have any surgical procedures involving the biliary tract, since Dilaudid could increase the chance of muscle spasms in this area.

Narcotics such as Dilaudid may mask or hide the symptoms of sudden or severe abdominal conditions, making diagnosis and treatment difficult.

Dilaudid can cause seizures when taken in high doses and, if you have a seizure disorder, can make the seizures worse.

Be sure to tell the doctor if you're sensitive to sulfites (preservatives commonly found in red wine), since Dilaudid contains this substance.

Possible food and drug interactions when taking Hydromorphone hydrochloride

Dilaudid is a central nervous system depressant and intensifies the effects of alcohol. Do not drink alcohol while taking Hydromorphone hydrochloride.

If Dilaudid is taken with certain other drugs, the effects of either could be increased, decreased, or altered. It is especially important to check with your doctor before combining Dilaudid with the following:

Antiemetics (drugs that prevent or lessen nausea and vomiting such as prochlorperazine and promethazine)Antihistamines such as diphenhydramineGeneral anestheticsOpioid antagonists such as naloxone and nelmefeneOther central nervous system depressants such as pentobarbital, temazepamOther narcotic analgesics such as meperidine and oxycodonePhenothiazines such as chlorpromazineSedative/hypnotics such as diazepam, triazolamTranquilizers such as alprazolamTricyclic antidepressants such as amitriptyline and imipramine

Special information if you are pregnant or breastfeeding

Do not take Dilaudid if you are pregnant or plan to become pregnant unless you are directed to do so by your doctor. Drug dependence occurs in newborns when the mother has taken narcotic drugs regularly during pregnancy. Withdrawal signs include irritability and excessive crying, tremors, overactive reflexes, increased breathing rate, increased stools, sneezing, yawning, vomiting, and fever. Dilaudid may appear in breast milk and could affect a nursing infant. If Hydromorphone hydrochloride is essential to your health, your doctor may advise you to discontinue breastfeeding your baby until your treatment is finished.
