Chlorthalidone Blood Pressure Pills Recalled: What to Check and What to Do
A batch of chlorthalidone 25 mg tablets was recalled nationwide. It is not a cancer story, and no cancer risk was reported. Here is what the FDA record says and what to do if you take this medicine.

This is not a cancer story. No cancer risk was reported with this recall. We cover it because many people in cancer treatment also take medicines for other conditions, and a recall notice can be confusing.
What was reported
Fox Business reported on September 29, 2026 that a blood pressure medicine was recalled nationwide. The product is chlorthalidone 25 mg tablets from Inventia Healthcare Limited of India. The story says the tablets failed dissolution testing. It also says this is the second recall of the product for the same reason.
The FDA's recall records match the story. They show two recalls by Inventia Healthcare, both nationwide, voluntary and still ongoing:
- September 2026 (D-0852-2026): 13,567 bottles of 100 tablets, NDC 64980-599-01, batch RISA24002, expiration 04/2027. The firm started the recall on September 3, 2026. The FDA classified it on September 17.
- June 2026 (D-0610-2026): 11,460 bottles, batch RISA24001 in 100-tablet bottles and batch RISB24002 in 1,000-tablet bottles, expiration 04/2027. The firm started the recall on June 5, 2026.
The FDA lists the reason for both as "Failed Dissolution Specifications." The two recalls cover different batches of the same product. The FDA record does not describe any patient harm. Fox Business did not say what patients should do. The FDA guidance below does.
What chlorthalidone is used for
MedlinePlus says chlorthalidone is used for high blood pressure and fluid retention. It is a diuretic, often called a water pill. It causes the kidneys to remove extra water and salt in the urine.
What "Class II" means
The FDA sorts recalls by risk. For Class II, the FDA says using the drug may cause temporary health effects, or the chance of a serious problem is remote. For Class II recalls, the FDA says people can generally keep taking the medicine unless the company or the FDA says otherwise. The FDA also says stopping a medicine can sometimes be more harmful than continuing it.
The FDA record gives the reason only as failed dissolution specifications. It does not say more, so we do not guess.
What to do
- Check your bottle. Look at the drug name, strength (25 mg), NDC, batch (lot) number and expiration date. The FDA says to compare the lot number on your label with the one in the recall notice.
- Call your pharmacy. Ask whether your bottle is from an affected batch. Ask what the company or the FDA has said to do. Companies may ask you to return the medicine to where you bought it.
- Do not stop or change your blood pressure medicine on your own. Ask your pharmacist, prescriber or oncology team first. Do not change how much you take.
- Tell your oncology team if you take a water pill. They may want to know when your blood pressure or swelling changes during treatment.
When to get help
Call 911 or go to an emergency department right away for chest pain, trouble breathing, fainting, or signs of a stroke such as face drooping, arm weakness or trouble speaking. Do not drive yourself.
Call your care team right away for a sudden big change in your blood pressure readings, new swelling, or readings that are much higher or lower than your team told you to expect.
Questions to ask your pharmacist or care team
- Is my bottle from a recalled batch?
- Should I keep taking this medicine until I get a replacement?
- Should my blood pressure be checked more often now?
- Could anything in my cancer treatment change my blood pressure or swelling?

Put the story in context
Prevention, possible warning signs, screening, and diagnosis
This story relates to patient-questions. The information below is general: it does not reveal anything else about a public person’s health, and not every point applies to every cancer. Personal advice depends on age, symptoms, family history, exposures, and medical history.
Prevention and risk reduction
Not every cancer can be prevented. Avoiding tobacco, protecting skin from ultraviolet radiation, limiting alcohol, staying active, and receiving recommended HPV or hepatitis B vaccination can lower the risk of certain cancers. A risk factor is not a prediction or a cause in one individual.
Symptoms and possible early signs
Possible signs vary and are often caused by conditions other than cancer. Changes worth discussing include a new lump, unexplained bleeding or weight loss, a persistent cough, lasting bowel or bladder changes, a changing skin spot, or symptoms that persist or worsen. Some early cancers cause no symptoms.
Screening and early detection
Screening looks for certain cancers before symptoms begin. Recommended tests exist only for some cancers and depend on age and risk. Screening can have benefits and harms; it is not the same as evaluating a new symptom, and there is no single routine scan or blood test that reliably screens for every cancer.
How cancer is diagnosed
Diagnosis may involve a history and exam, imaging, laboratory tests, and often a biopsy. Pathology can identify the cancer type and may test biomarkers that guide treatment. Symptoms, screening results, tumor markers, or online stories alone cannot confirm cancer.
A public story may encourage questions, but it should not be used to estimate your risk or choose testing. Contact a healthcare professional about a persistent or concerning change. Seek urgent care for severe or rapidly worsening symptoms.
