Kidney stone pain can be sudden, severe and difficult to tolerate. It commonly occurs when a stone moves into the ureter and interferes with urine flow. Pain may be felt in the side or back and can travel toward the lower abdomen or groin. Nausea, vomiting and blood in the urine may also occur.

People searching for a pain relief tablet for kidney stones should know that there is no single tablet that is suitable for everyone.

The appropriate pain medicine depends on factors such as:

• Kidney function

• Stone location and size

• Severity of pain

• Hydration status

• Stomach health

• Pregnancy

• Other medicines being taken

• Heart, liver or other medical conditions

For otherwise suitable patients, nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used for renal colic. Paracetamol may also be considered in appropriate situations. A doctor or pharmacist should determine which option is safest for the individual.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides evaluation of kidney function and kidney-related conditions associated with stone disease.

Why Do Kidney Stones Cause So Much Pain?

A kidney stone may remain inside the kidney without causing significant symptoms.

Pain often develops when the stone moves into the urinary tract and causes obstruction or irritation.

The pain may:

• Begin suddenly

• Come in waves

• Affect one side of the back or flank

• Move toward the abdomen

• Spread toward the groin

• Occur with nausea or vomiting

The severity of pain does not necessarily tell you how large the stone is.

A relatively small ureteral stone can cause intense pain if it obstructs urine flow.

Which Pain Relief Medicines May Be Used?

NSAIDs

NSAIDs are commonly used for renal colic because they reduce inflammation and pain associated with ureteral obstruction.

Examples include medicines containing:

• Ibuprofen

• Naproxen

• Diclofenac

• Other prescription or non-prescription NSAIDs

However, NSAIDs are not appropriate for everyone.

They can affect kidney function and may increase the risk of acute kidney injury, particularly in people who are dehydrated or already have kidney disease.

Therefore, do not repeatedly take an NSAID for kidney stone pain without checking whether it is appropriate for you.

Paracetamol

Paracetamol may be considered for pain relief in appropriate patients.

It does not belong to the NSAID group and may be an alternative when NSAIDs are unsuitable, depending on the individual's medical history.

However, the correct dose and maximum daily amount must be followed carefully.

People with liver disease, heavy alcohol use or other relevant conditions should discuss paracetamol use with a healthcare professional.

Stronger Prescription Pain Medicines

If severe renal colic does not respond adequately to first-line pain treatment, a doctor may consider stronger prescription analgesics.

These medicines can have important side effects, including drowsiness, nausea, constipation and dependence risk with some drugs.

They should be used only under medical supervision.

Is Ibuprofen Safe for Kidney Stone Pain?

Ibuprofen can relieve pain in some people with kidney stones, but it is not automatically safe for everyone.

Extra caution is required in people with:

• Chronic kidney disease

• Dehydration

• Low blood pressure

• Stomach ulcers or gastrointestinal bleeding

• Certain heart conditions

• Certain blood-thinning medicines

• Pregnancy

• Other conditions in which NSAIDs are unsuitable

NIDDK warns that NSAIDs can damage the kidneys or contribute to acute kidney injury, particularly when used during dehydration or in people at increased kidney risk.

Therefore, do not choose an NSAID simply because it is available over the counter.

What About Diclofenac for Kidney Stone Pain?

Diclofenac is an NSAID and may be prescribed for renal colic in suitable patients.

However, the same kidney, stomach, cardiovascular and pregnancy-related precautions apply to diclofenac as to other NSAIDs.

Do not combine multiple NSAIDs unless specifically instructed by a healthcare professional.

For example, taking ibuprofen and diclofenac together does not necessarily provide safer or better pain relief and can increase the risk of adverse effects.

Can Paracetamol Alone Relieve Kidney Stone Pain?

It may help some patients, particularly when NSAIDs are unsuitable.

However, severe renal colic can require stronger or different treatment.

If pain remains severe despite an appropriate painkiller, the solution is not necessarily to keep increasing tablets.

Persistent severe pain may indicate that the stone requires active treatment or that another complication needs evaluation.

Should You Take a Painkiller on an Empty Stomach?

The answer depends on the medicine.

Some painkillers, especially NSAIDs, can irritate the stomach and may increase the risk of gastrointestinal complications.

Follow the instructions on the prescribed medicine and ask a pharmacist or doctor about the appropriate way to take it.

Avoid taking more tablets simply because the pain has not improved quickly.

What If You Have Kidney Disease and a Kidney Stone?

This situation requires additional caution.

A person with CKD may have fewer safe options for pain treatment because some commonly available painkillers can worsen kidney function.

NIDDK specifically recommends caution with NSAIDs in people with kidney disease.

If you already have:

• High creatinine

• Reduced eGFR

• Protein in urine

• Previous acute kidney injury

• A kidney transplant

• Dialysis

• Significant dehydration

consult your healthcare professional before taking an NSAID for stone pain.

What If Vomiting Is Preventing You From Taking Tablets?

Kidney stone pain can be accompanied by nausea and vomiting.

If you repeatedly vomit after taking medicine or cannot keep fluids down, oral treatment may not be effective.

Severe vomiting can also lead to dehydration, which may further affect kidney function.

In a medical setting, treatment may include assessment of hydration, injectable or intravenous medicines and appropriate fluids when clinically indicated.

NIDDK notes that people who are vomiting and dehydrated from a kidney stone may require hospital treatment and IV fluids.

Does a Pain Relief Tablet Remove the Kidney Stone?

No.

A painkiller treats the symptom; it does not necessarily remove the stone.

A small stone may pass naturally in some circumstances, while a larger or obstructing stone may require active treatment. Kidney stone management depends on factors such as size, location and stone characteristics.

Depending on the situation, treatment may include:

• Observation

• Medical management

• Shock wave lithotripsy

• Ureteroscopy with stone removal or laser fragmentation

• Percutaneous nephrolithotomy for selected larger stones

Therefore, repeated pain tablets should not be used as a substitute for appropriate stone evaluation.

How Long Can Kidney Stone Pain Last?

The duration varies considerably.

Pain may come and go while a stone moves through the ureter. Some stones pass without a procedure, while others remain lodged and continue causing symptoms.

Persistent or recurrent pain should be evaluated, particularly when there is evidence of obstruction.

A stone that continues to cause significant symptoms may require active removal rather than prolonged reliance on pain medicine.

When Is Kidney Stone Pain an Emergency?

Seek urgent medical attention if kidney stone symptoms occur with:

• Fever

• Chills

• Very little or no urine

• Severe or worsening pain

• Persistent vomiting

• Fainting

• Severe weakness

• Confusion

• Significant dehydration

• Known urinary obstruction with infection

A blocked urinary tract combined with infection can become a serious medical emergency.

NIDDK also advises prompt medical evaluation for kidney stone symptoms, particularly severe pain, bleeding or urinary problems.

Why Fever With Kidney Stone Pain Is Concerning

A kidney stone accompanied by fever or chills should not be treated simply with a painkiller.

An obstructing stone can interfere with urine drainage, while an infection can develop behind the obstruction.

In such circumstances, antibiotics alone may not be sufficient if urine drainage is blocked. The urinary obstruction may require urgent specialist management.

This is one reason patients with severe stone symptoms should not repeatedly self-medicate at home.

Can Drinking Water Replace Pain Medicine?

Drinking an appropriate amount of fluid can be part of kidney stone care, but water is not a painkiller.

People should not force large quantities of water while experiencing severe obstructive stone pain.

If vomiting, kidney impairment, heart disease or fluid restrictions are present, fluid intake must be individualized.

NIDDK recommends discussing fluid needs with a healthcare professional when kidney failure or other health problems affect the ability to drink normally.

What Tests May Be Needed for Kidney Stone Pain?

If the diagnosis is uncertain or symptoms are severe, a doctor may recommend:

Urine Testing

Urinalysis can look for:

• Blood

• Infection

• Crystals

• Other abnormalities

Blood Tests

Depending on the situation:

• Creatinine

• eGFR

• Electrolytes

• Blood count

• Other relevant tests

Imaging

Ultrasound or CT imaging may be used to determine:

• Stone location

• Stone size

• Number of stones

• Degree of obstruction

• Possible complications

The results help determine whether pain management alone is reasonable or whether stone removal is needed.

When Does a Kidney Stone Need More Than Pain Relief?

A stone may need active treatment when it:

• Is unlikely to pass naturally

• Causes persistent or recurrent pain

• Blocks urine flow

• Causes recurrent infection

• Affects kidney function

• Remains in the urinary tract despite appropriate observation

NIDDK notes that larger stones, stones blocking the urinary tract or stones causing significant pain may require treatment such as shock wave lithotripsy, ureteroscopy or percutaneous nephrolithotomy.

What Happens During Kidney Stone Removal?

The procedure depends on the stone.

Ureteroscopy

A small scope is passed through the urinary tract to locate the stone. The stone may be removed or fragmented, including with laser energy.

Shock Wave Lithotripsy

External shock waves are used to break selected stones into smaller fragments.

PCNL

For selected larger kidney stones, a small access tract is created into the kidney so instruments can fragment and remove the stone.

A temporary ureteral stent may be used after some procedures to support urine drainage.

How Can Future Kidney Stone Pain Be Prevented?

Once the acute episode has settled, prevention becomes important.

Depending on the type of stone, a specialist may recommend:

• Appropriate fluid intake

• Lower dietary sodium

• Individualized dietary changes

• Stone analysis

• Blood tests

• Urine testing

• 24-hour urine evaluation in selected patients

• Preventive medicines when indicated

NIDDK notes that prevention strategies depend on the type and cause of the stone.

Frequently Asked Questions

Which tablet is best for kidney stone pain?

NSAIDs are commonly used for renal colic when they are medically appropriate. Paracetamol may also be considered in suitable patients. The safest option depends on kidney function, dehydration status, other illnesses and medicines.

Can I take ibuprofen for kidney stone pain?

Some people can take ibuprofen, but it is not suitable for everyone. People with kidney disease, dehydration, low blood pressure and certain other conditions should avoid or use NSAIDs only under medical advice.

Is paracetamol good for kidney stone pain?

Paracetamol can provide pain relief for some patients and may be considered when NSAIDs are unsuitable. The appropriate dose depends on the individual, and people with liver disease or other risk factors should seek medical advice.

Does a painkiller dissolve kidney stones?

No. Painkillers relieve symptoms but do not dissolve most kidney stones. Stone treatment depends on its size, location, composition and clinical effects.

Can I take two different painkillers together?

Do not combine pain medicines without checking with a doctor or pharmacist. In particular, taking multiple NSAIDs together can increase the risk of adverse effects.

What should I do if the painkiller does not work?

Persistent severe pain should be medically evaluated. The stone may be obstructing urine flow or may require active treatment rather than additional pain tablets.

Can kidney stone pain cause vomiting?

Yes. Severe renal colic can be associated with nausea and vomiting.

When should kidney stone pain be treated urgently?

Seek urgent medical attention for severe or worsening pain accompanied by fever, chills, very little or no urine, persistent vomiting, severe weakness, confusion or other signs of serious illness.

Conclusion

Finding the right pain relief tablet for kidney stones depends on the individual's kidney function, medical history and severity of symptoms. NSAIDs are commonly used for renal colic when appropriate, while paracetamol and other prescription options may be considered in selected situations.

However, pain relief should not be confused with stone treatment. A tablet may reduce discomfort without removing the underlying stone.

If pain persists, the stone is obstructing urine flow, kidney function is affected, or infection is suspected, specialist evaluation may be necessary. Larger or problematic stones may require procedures such as ureteroscopy, shock wave lithotripsy or PCNL.
