Dilaudid is used to relieve moderate to acute pain. It is a narcotic analgesic and functions by changing how the central nervous system reacts to pain, explains Everyday Health. It is also known as hydromorphone.
Dilaudid is available as either immediate-release or sustained-release tablets, an injection, an oral solution and a rectal suppository, reports MedicineNet. Pregnant women and lactating mothers should consult a doctor before using Dilaudid, recommends Everyday Health. Patients with severe asthma or breathing problems, a blockage in the stomach or intestines, paralytic ileus or allergic reactions to narcotic medicines should not use Dilaudid, advises Drugs.com.
Its side effects include dizziness, nausea and vomiting, constipation, and stomach pain. It may also cause extreme feelings of happiness or sadness, sweating, itching, flushing and dry mouth, notes Drugs.com. Mixing alcohol with Dilaudid may cause death.
