Do not suddenly stop taking Dilaudid, or you could face unpleasant withdrawal symptoms. To prevent withdrawal, your medical healthcare provider may lower your dosage gradually. Inform your doctor instantly if you have any withdrawal symptoms, such as

● Nausea,
● Restlessness,
● Mental changes or mood swings (including trouble sleeping, anxiety, suicidal thoughts),
● Runny nose,
● Watery eyes,
● Sweating,
● Diarrhea,
● Sudden changes in behavior, or
● Muscle aches.

Though this medication helps various people, sometimes Dilaudid addiction takes place. The risk is greater if you already have a substance use disorder, such as addiction to drugs or alcohol. Take Dilaudid precisely as per the doctor's prescription to lower the risk of addiction.

Dilaudid overdose can prove fatal, especially in a child or a person taking it without a prescription. Overdose symptoms of Dilaudid may include:

● Severe drowsiness;
● Shallow breathing and heart rate;
● Cold and clammy skin;
● Muscle weakness;
● Fainting; and
● Pinpoint pupils

Avoid consumption of alcohol. It can result in dangerous side effects or cause death. Dilaudid may impair your reactions or thinking. Avoid driving any vehicle or operating types of machinery until you know this medicine's impact on you. Severe drowsiness or dizziness can cause accidental falls or severe injuries.

Nausea, constipation, vomiting, dizziness, lightheadedness, sweating, drowsiness, dry mouth, or flushing may occur as Dilaudid side effects. Some side effects may decrease after a short while of taking this medication. If any of these side effects are bothersome, or persist, or worsen, tell your doctor or pharmacist instantly.

To prevent constipation, drink enough water, eat dietary fiber, and exercise. To reduce the risk of lightheadedness (drowsiness) and dizziness, stand up slowly while rising from a sitting or lying position.

Tell your medical healthcare provider immediately if you have any severe side effects due to the use of Dilaudid, including:

● Sleep apnea (interrupted breathing during sleep);
