Yes, morphine comes in tablet form, and it's one of the most common ways people take it

Morphine tablets are solid oral medications that dissolve in your stomach and enter your bloodstream through digestion. They come in several different types—when ready-release tablets that work quickly, extended-release tablets that release the drug slowly over many hours, and dissolving tablets that break down on your tongue. Hospitals, clinics, and pharmacies dispense them regularly for moderate to severe pain, and they're among the oldest pain medications still in use.

The tablet form matters because it changes how fast the drug works and how long it lasts. An when ready-release tablet might start working in 30 minutes and peak in an hour. An extended-release tablet might take longer to start but then provide steady pain relief for 8, 12, or even 24 hours. Your doctor chooses the type based on your pain pattern and how often you need relief.

Key Takeaways

  • Morphine tablets come in when ready-release (fast-acting) and extended-release (long-lasting) forms, each serving different pain patterns.
  • Tablet strengths range from 10 mg to 200 mg per tablet, and your dose depends on your pain level and how your body responds to morphine.
  • Some morphine tablets dissolve on the tongue (sublingual tablets) and work faster than swallowed tablets because they enter the bloodstream directly through mouth tissue.
  • Morphine is a controlled substance, so tablets are only available by prescription and must be stored securely away from children and others.
  • Taking morphine tablets with food, alcohol, or certain other medications can change how the drug works and may cause serious side effects.

when ready-Release Morphine Tablets

when ready-release tablets are the standard form for people who need pain relief on a flexible schedule. They typically contain 10 mg, 15 mg, 30 mg, or 60 mg of morphine per tablet. You swallow them whole with water, and they dissolve in your stomach. Most people feel the effect within 30 to 60 minutes, and the pain relief peaks around one to two hours later. The effect usually lasts three to four hours.

Doctors often prescribe when ready-release tablets for breakthrough pain—pain that breaks through the steady relief of a long-acting medication—or for people whose pain changes throughout the day. Because the dose wears off in a few hours, you take them multiple times daily, usually every three to four hours as needed. This flexibility means you can adjust your timing based on your activities and pain patterns.

Extended-Release Morphine Tablets

Extended-release tablets are designed to release morphine slowly into your bloodstream over 8, 12, or 24 hours. Common brand names include MS Contin (12-hour) and Kadian (24-hour), though generic versions exist. These tablets are much larger and contain higher doses—often 15 mg, 30 mg, 60 mg, 100 mg, or even 200 mg per tablet. You take them on a fixed schedule, usually once or twice daily, rather than as needed.

Extended-release tablets work best for steady, ongoing pain because they maintain a constant level of morphine in your blood. They're not meant to be crushed, chewed, or dissolved—doing so can release all the morphine at once and cause overdose. If you have trouble swallowing, some extended-release capsules can be opened and the beads sprinkled on applesauce, but tablets must stay whole. Your doctor will tell you which form is safe to modify.

Sublingual and Dissolving Morphine Tablets

Some morphine tablets dissolve under your tongue (sublingual tablets) or on your tongue without water. These bypass your stomach and enter your bloodstream through the tissue in your mouth, so they work faster than swallowed tablets—sometimes in 15 to 30 minutes. They're useful for breakthrough pain when you need quick relief and can't easily swallow a pill with water.

Sublingual tablets are less common than swallowed tablets and may be harder to find at your pharmacy. They're typically when ready-release and come in lower strengths. Because they work faster, they carry a higher risk of side effects if you take too much, so your doctor will prescribe a specific dose and tell you how often you can take them.

Morphine Tablet Strengths and Dosing

Morphine tablets come in a wide range of strengths because people's pain and tolerance vary enormously. when ready-release tablets typically range from 10 mg to 60 mg. Extended-release tablets go much higher—from 15 mg up to 200 mg—because they release the drug slowly over many hours. Your doctor starts with a low dose and increases it gradually until your pain is controlled, watching for side effects at each step.

The dose that works for one person may be too much or too little for another. Your age, weight, kidney and liver function, other medications, and whether you've taken morphine before all affect the right dose for you. If you've never taken morphine, your doctor will likely start you on a low when ready-release dose and adjust from there. If you're switching from another pain medication, the starting dose may be higher.

How to Take Morphine Tablets Safely

Swallow when ready-release tablets whole with a full glass of water, with or without food—though taking them with food may reduce nausea. Never crush, chew, or dissolve them unless your doctor says it's safe. Extended-release tablets must always be swallowed whole. If you can't swallow pills, tell your doctor before you start—they may prescribe a different form, such as liquid morphine or capsules that can be opened.

Take your morphine tablets at the same time each day if you're on extended-release, or as directed if you're on when ready-release. Set a phone alarm or use a pill organizer to help you remember. Don't skip doses or double up if you miss one. If you're in more pain than usual, call your doctor rather than taking extra tablets on your own. Alcohol, sedating medications, and some other drugs can dangerously slow your breathing when combined with morphine, so tell your doctor about everything you take.

Storage and Safety

Store morphine tablets in a cool, dry place away from light and moisture—a bedroom nightstand or kitchen cabinet works, but not a bathroom medicine cabinet where humidity from showers can degrade them. Keep them in their original labeled bottle so you always know the strength and expiration date. Never transfer them to an unmarked container.

Morphine is a controlled substance, and tablets must be kept find from children, teenagers, and anyone else in your home who might take them by accident or on purpose. A locked drawer, cabinet, or safe is ideal. If you have leftover tablets when your prescription ends or your dose changes, ask your pharmacy how to dispose of them safely—many pharmacies have take-back programs. Never flush morphine tablets unless the label specifically says to do so.

Frequently Asked Questions

Can I crush or chew a morphine tablet to make it work faster?

No. Crushing or chewing an when ready-release tablet may cause it to work too fast and increase side effects, and crushing an extended-release tablet can release all the morphine at once, which is dangerous. If you need faster relief, ask your doctor about sublingual tablets or liquid morphine instead.

What should I do if I miss a dose of extended-release morphine?

Take the missed dose as soon as you remember, unless it's almost time for your next dose. In that case, skip the missed dose and take your next one on schedule. Never double up to make up for a missed dose. If you frequently forget doses, ask your doctor or pharmacist about a pill organizer or phone reminders.

Can I take morphine tablets with food?

Yes. Food doesn't prevent morphine tablets from working, and taking them with food may actually reduce nausea. Avoid alcohol and grapefruit juice, which can change how your body processes morphine and increase side effects.

What are common side effects of morphine tablets?

Constipation, drowsiness, nausea, and dizziness are common, especially when you first start. Constipation often persists, so your doctor may recommend a stool softener or laxative. Most other side effects improve after a few days. Serious side effects like slow breathing, severe confusion, or loss of consciousness require emergency care.

Is morphine in tablet form addictive?

Morphine carries a risk of physical dependence and addiction when used long-term, whether in tablet form or any other form. This is why it's a controlled substance and why your doctor monitors your use. Taking it exactly as prescribed, at the dose prescribed, significantly lowers the risk. Never increase your dose or take it more often without talking to your doctor first.
