Introduction
Kidney stones can cause sudden and severe pain, nausea, vomiting, blood in the urine, and difficulty passing urine. When a stone is small and located in a suitable part of the urinary tract, it may pass naturally without a procedure. In these situations, certain medicines can help manage symptoms and, in selected patients, improve the likelihood of stone passage.
Many people search for “medicine to help pass kidney stones” because they want to avoid surgery or a procedure. However, there is no single medicine that works for every kidney stone. Treatment depends on the stone's size, location, composition, symptoms, kidney function, and whether there is an infection or urinary obstruction.
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, a super specialist nephrologist, provides comprehensive evaluation of kidney stones, kidney function assessment, metabolic evaluation, preventive care, and guidance regarding appropriate medical or urological treatment.
Can Medicine Help Pass a Kidney Stone?
Yes, medicines can help some patients pass a kidney stone naturally.
The likelihood of spontaneous passage is generally higher for smaller stones, particularly certain stones located in the ureter. As stone size increases, the chance of natural passage generally decreases.
Medical treatment may include:
-
Pain-relieving medicines
-
Medicines for nausea and vomiting
-
Selected medical expulsive therapy
-
Appropriate fluid intake
-
Medicines to prevent future stones based on metabolic evaluation
The appropriate treatment should be determined by a healthcare professional after evaluating the stone.
Medicines That May Help Pass Kidney Stones
Medical Expulsive Therapy
In selected patients with a ureteral stone, medicines known as alpha blockers may be considered to help relax the ureter and facilitate stone passage.
Tamsulosin is one medicine that may be used for this purpose in appropriate patients.
It is not suitable for everyone, and its effectiveness depends on factors such as:
-
Stone size
-
Stone location
-
Patient characteristics
-
Likelihood of spontaneous passage
A doctor should determine whether medical expulsive therapy is appropriate.
Pain Relief Medicines
Kidney stones can cause severe colicky pain.
Doctors may recommend appropriate pain-relieving medicines depending on the patient's health and kidney function.
Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used for renal colic in suitable patients, but they may not be appropriate for people with:
-
Chronic kidney disease
-
Acute kidney injury
-
Significant dehydration
-
Certain stomach problems
-
Some cardiovascular conditions
-
Certain medication interactions
People with kidney problems should not take painkillers repeatedly without medical advice.
Medicines for Nausea and Vomiting
Kidney stones may cause significant nausea or vomiting.
When necessary, doctors may prescribe anti-nausea medicines to improve comfort and help patients maintain appropriate fluid intake.
Persistent vomiting should not be ignored because dehydration can worsen kidney function and make stone-related problems more difficult to manage.
Can Medicines Dissolve Kidney Stones?
Most kidney stones cannot be dissolved with tablets.
The treatment depends on the stone's chemical composition.
Uric Acid Stones
Selected uric acid stones may sometimes be dissolved with medically supervised urine alkalinization, which raises urine pH and helps the stone dissolve.
This treatment requires appropriate diagnosis and monitoring.
Calcium Stones
Calcium oxalate and calcium phosphate stones generally cannot be dissolved with medication.
Treatment usually focuses on:
-
Supporting natural passage when appropriate
-
Removing the stone when necessary
-
Preventing future stones
Therefore, it is important to know that a “stone dissolving medicine” is not appropriate for every type of kidney stone.
Does Drinking Water Help Pass Kidney Stones?
Adequate fluid intake may support the passage of selected small stones and is important for preventing future stones.
However, drinking excessive amounts of water rapidly does not guarantee that a stone will pass.
Very high fluid intake may be unsafe when there is:
-
Significant urinary obstruction
-
Severe kidney dysfunction
-
Heart failure
-
A medical fluid restriction
Your doctor can advise you about the appropriate amount of fluid based on your condition.
How Do Doctors Decide Whether Medicine Is Enough?
Before recommending conservative treatment, the doctor may assess:
Stone Size
Smaller stones are more likely to pass naturally than larger stones.
Stone Location
The location of a stone within the urinary tract affects its likelihood of spontaneous passage.
Symptoms
Severe or persistent pain, repeated vomiting, or difficulty urinating may require more active treatment.
Kidney Function
Blood tests such as serum creatinine and eGFR help determine whether the kidneys are being affected.
Urinary Obstruction
Imaging may show whether the stone is blocking urine flow.
Infection
A stone associated with urinary infection and obstruction can be a medical emergency.
Tests Used to Evaluate Kidney Stones
At Prabhakar Bhurke Clinic, evaluation may include:
Urine Testing
Urine tests can identify:
-
Blood
-
Infection
-
Crystals
-
Protein
-
Other urinary abnormalities
A urine culture may be required when infection is suspected.
Blood Tests
Depending on the situation, testing may include:
-
Serum creatinine
-
eGFR
-
Electrolytes
-
Calcium
-
Uric acid
-
Other metabolic investigations
Imaging
Depending on the clinical situation, imaging may include:
-
Kidney and urinary tract ultrasound
-
Non-contrast CT scan
-
Other imaging when clinically indicated
Imaging helps determine the stone's size, location, and effect on urine drainage.
When Should You Not Rely on Medicine Alone?
Medication may not be sufficient when a stone is:
-
Large
-
Causing persistent obstruction
-
Causing worsening kidney function
-
Associated with uncontrolled pain
-
Associated with persistent vomiting
-
Unlikely to pass naturally
-
Associated with infection
A stone that blocks urine flow while the urinary system is infected requires urgent medical treatment and drainage, rather than waiting for medicines to make the stone pass.
Kidney Stone Procedures When Medicines Do Not Work
If a stone does not pass naturally or creates significant complications, a urologist may recommend a procedure.
Possible treatments include:
Shock Wave Lithotripsy
Shock waves are used to break a stone into smaller fragments that can then pass through the urinary tract.
Ureteroscopy and Laser Lithotripsy
A urologist uses a thin scope to reach the stone and breaks it into smaller pieces using a laser.
RIRS
Retrograde intrarenal surgery uses a flexible ureteroscope to reach stones inside the kidney and fragment them, often using a laser.
PCNL
Percutaneous nephrolithotomy is commonly considered for larger or complex kidney stones. It involves accessing the kidney through a small opening in the back to remove the stone.
The most appropriate procedure depends on stone size, location, anatomy, kidney function, and other patient-specific factors.
Warning Signs That Require Urgent Medical Attention
Seek urgent medical care if a kidney stone is associated with:
-
Fever or chills
-
Severe or worsening pain
-
Difficulty passing urine
-
Very low or no urine output
-
Persistent vomiting
-
Severe weakness
-
Confusion
-
Known urinary obstruction
-
A single functioning kidney with concerning symptoms
Fever with a blocked urinary system can indicate an infected obstruction and requires urgent assessment.
Do not attempt to manage these symptoms with home remedies or stone medicines alone.
How to Prevent Future Kidney Stones
Passing one kidney stone does not mean that another will not develop.
Depending on the type of stone and metabolic evaluation, prevention may include:
-
Drinking an appropriate amount of fluid
-
Reducing excessive salt intake
-
Following a balanced diet
-
Maintaining normal dietary calcium intake unless advised otherwise
-
Avoiding excessive intake of stone-forming foods when appropriate
-
Maintaining a healthy body weight
-
Taking preventive medicines when prescribed
-
Completing recommended metabolic testing
The prevention plan should be individualized according to the stone type and urine findings.

Frequently Asked Questions
What is the best medicine to help pass a kidney stone?
There is no single medicine that is best for everyone. In selected patients with ureteral stones, an alpha blocker such as tamsulosin may be considered to facilitate stone passage. Pain and nausea medicines may also be prescribed according to the patient's condition.
Can tamsulosin help pass kidney stones?
Tamsulosin may help selected patients with certain ureteral stones pass the stone more easily. Its benefit depends on factors such as stone size and location, and it should be used under medical guidance.
Can I take painkillers for kidney stone pain?
Pain medicines can help control renal colic, but some medicines, particularly NSAIDs, may be unsafe in people with kidney disease, dehydration, or certain other medical conditions. Consult a healthcare professional before taking them repeatedly.
Can kidney stones dissolve with medicine?
Most calcium-based kidney stones cannot be dissolved with medicines. Selected uric acid stones may dissolve with medically supervised urine alkalinization.
Does drinking more water make a kidney stone pass faster?
Appropriate hydration may support passage of some small stones, but drinking excessive quantities of water does not guarantee faster passage and can be unsafe in certain conditions.
When does a kidney stone require surgery?
A procedure may be necessary when the stone is large, causes persistent obstruction, causes worsening kidney function, produces uncontrolled symptoms, or is unlikely to pass naturally. A urologist determines the appropriate procedure.
Can antibiotics remove kidney stones?
No. Antibiotics treat bacterial infection but do not remove an ordinary kidney stone. If infection occurs behind an obstructed urinary system, urgent drainage and antibiotic treatment may be required.
Conclusion
The right medicine to help pass kidney stones depends on the stone's size, location, symptoms, kidney function, and overall health. Selected patients with ureteral stones may benefit from medical expulsive therapy such as tamsulosin, while pain and nausea medicines can help control symptoms.
However, medicines do not replace procedures when a stone is large, obstructing urine flow, causing worsening kidney function, or associated with infection. Most calcium stones also cannot be dissolved with medication, although selected uric acid stones may respond to medically supervised urine alkalinization.
