AUDIENCE: Consumer, Patient, Health Professional, Pharmacy
ISSUE: FDA is warning that use of NSAIDs around 20 weeks or later in pregnancy may cause rare but serious kidney problems in an unborn baby. This can lead to low levels of amniotic fluid surrounding the baby and possible complications.
For prescription NSAIDs, FDA is requiring changes to the prescribing information to describe the risk of kidney problems in unborn babies that result in low amniotic fluid.
For over-the-counter (OTC) NSAIDs intended for use in adults, FDA will also update the Drug Facts labels, available at: http://bit.ly/2Uadlbz. These labels already warn to avoid using NSAIDs during the last 3 months of pregnancy because the medicines may cause problems in the unborn child or complications during delivery. The Drug Facts labels already advise pregnant and breastfeeding women to ask a health care professional before using these medicines.
- are a class of medicines available by prescription and OTC. They are some of the most commonly used medicines for pain and fever.
- are used to treat medical conditions such as arthritis, menstrual cramps, headaches, colds, and the flu.
- work by blocking the production of certain chemicals in the body that cause inflammation.
- are available alone and combined with other medicines. Examples of NSAIDs include aspirin, ibuprofen, naproxen, diclofenac, and celecoxib.
Common side effects of NSAIDs include: stomach pain, constipation, diarrhea, gas, heartburn, nausea, vomiting, and dizziness.
- If you are pregnant, do not use NSAIDs at 20 weeks or later in pregnancy unless specifically advised to do so by your health care professional because these medicines may cause problems in your unborn baby.
- Many OTC medicines contain NSAIDs, including those used for pain, colds, flu, and insomnia, so it is important to read the Drug Facts labels, available at: http://bit.ly/2Uadlbz, to find out if the medicines contain NSAIDs.
- Talk to your health care professional or pharmacist if you have questions or concerns about NSAIDs or which medicines contain them.
- Other medicines, such as acetaminophen, are available to treat pain and fever during pregnancy. Talk to your pharmacist or health care professional for help deciding which might be best.
Health Care Professionals
- FDA recommends that health care professionals should limit prescribing NSAIDs between 20 to 30 weeks of pregnancy and avoid prescribing them after 30 weeks of pregnancy. If NSAID treatment is determined necessary, limit use to the lowest effective dose and shortest duration possible. Consider ultrasound monitoring of amniotic fluid if NSAID treatment extends beyond 48 hours and discontinue the NSAID if oligohydramnios is found. FDA is warning that use of NSAIDs around 20 weeks gestation or later in pregnancy may cause fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment.
- These adverse outcomes are seen, on average, after days to weeks of treatment, although oligohydramnios has been infrequently reported as soon as 48 hours after NSAID initiation.
- Oligohydramnios is often, but not always, reversible with treatment discontinuation.
- Complications of prolonged oligohydramnios may include limb contractures and delayed lung maturation. In some postmarketing cases of impaired neonatal renal function, invasive procedures such as exchange transfusion or dialysis were required.
- If NSAID treatment is deemed necessary between 20 to 30 weeks of pregnancy, limit use to the lowest effective dose and shortest duration possible. As currently described in the NSAID labels, avoid prescribing NSAIDs at 30 weeks and later in pregnancy because of the additional risk of premature closure of the fetal ductus arteriosus.
- The above recommendations do not apply to low-dose 81 mg aspirin prescribed for certain conditions in pregnancy.
- Consider ultrasound monitoring of amniotic fluid if NSAID treatment extends beyond 48 hours. Discontinue the NSAID if oligohydramnios occurs and follow up according to clinical practice.

For female patients:
Do not take diclofenac and misoprostol if you are pregnant or plan to become pregnant. If you become pregnant or think you may be pregnant while taking diclofenac and misoprostol, stop taking the medication and call your doctor immediately. Diclofenac and misoprostol may cause miscarriage (pregnancy loss), serious bleeding, or premature birth (baby is born too early) if taken during pregnancy.
Women who can become pregnant generally should not take diclofenac and misoprostol. However, you and your doctor may decide that diclofenac and misoprostol combination is needed to treat your condition. In that case you must:
- agree to use a reliable method of birth control during your treatment and for at least 1 month or one menstrual cycle after your treatment;
- have a negative blood test for pregnancy no longer than 2 weeks before you start taking diclofenac and misoprostol;
- begin taking the medication only on the second or third day of the next normal menstrual period.
For all patients:
People who take nonsteroidal anti-inflammatory drugs (NSAIDs) (other than aspirin) such as diclofenac and misoprostol combination may have a higher risk of having a heart attack or a stroke than people who do not take these medications. These events may happen without warning and may cause death. This risk may be higher for people who take NSAIDs for a long time. Do not use an NSAID such as diclofenac and misoprostol combination if you have recently had a heart attack, unless directed to do so by your doctor. Tell your doctor if you or anyone in your family has or has ever had heart disease, a heart attack, or a stroke, if you smoke, and if you have or have ever had high cholesterol, high blood pressure, or diabetes. Get emergency medical help right away if you experience any of the following symptoms: chest pain, shortness of breath, weakness in one part or side of the body, or slurred speech.
If you will be undergoing a coronary artery bypass graft (CABG; a type of heart surgery), you should not take diclofenac and misoprostol right before or right after the surgery.
NSAIDs such as diclofenac may cause ulcers, bleeding, or holes in the stomach or intestine. Misoprostol is taken in combination with diclofenac to protect the stomach and intestine, but may not prevent all damage to these parts of the body. Problems with the stomach and intestine may develop at any time during treatment, may happen without warning symptoms, and may cause death. The risk may be higher for people who take NSAIDs for a long time, are older in age, have poor health, smoke, or drink large amounts of alcohol while taking diclofenac and misoprostol. Tell your doctor if you take any of the following medications: anticoagulants ('blood thinners') such as warfarin (Coumadin, Jantoven); aspirin; other NSAIDs such as ibuprofen (Advil, Motrin) and naproxen (Aleve, Naprosyn); oral steroids such as dexamethasone, methylprednisolone (Medrol), and prednisone (Rayos); selective serotonin reuptake inhibitors (SSRIs) such as citalopram (Celexa), fluoxetine (Prozac, Sarafem, Selfemra, in Symbyax), fluvoxamine (Luvox), paroxetine (Brisdelle, Paxil, Pexeva), and sertraline (Zoloft); or serotonin norepinephrine reuptake inhibitors (SNRIs) such as desvenlafaxine (Khedezla, Pristiq), duloxetine (Cymbalta), and venlafaxine (Effexor XR). Tell your doctor if you have any bleeding in your stomach or intestines or if you have any of these symptoms: vomiting a substance that is bloody or looks like coffee grounds, blood in the stool, or black and tarry stools. before you begin your treatment with diclofenac and misoprostol. Your doctor will probably tell you not to take diclofenac and misoprostol. Also tell your doctor if you have or have ever had ulcers or a bleeding disorder. If you experience any of the following symptoms, stop taking diclofenac and misoprostol and call your doctor: stomach pain, heartburn, vomiting a substance that is bloody or looks like coffee grounds, blood in the stool, or black and tarry stools.
Keep all appointments with your doctor and the laboratory. Your doctor will monitor your symptoms carefully and will probably order certain tests to check your body's response to diclofenac and misoprostol. Be sure to tell your doctor how you are feeling so that your doctor can prescribe the right amount of medication to treat your condition with the lowest risk of serious side effects.
Do not give this medication to anyone else, especially a woman who is or could become pregnant.
Your doctor or pharmacist will give you the manufacturer's patient information sheet for diclofenac and misoprostol and the general Medication Guide for NSAIDs when you begin your treatment and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the patient information sheet and Medication Guide.
Why is this medication prescribed?
The combination of diclofenac and misoprostol is used to relieve the pain, tenderness, swelling, and stiffness caused by osteoarthritis (arthritis caused by a breakdown of the lining of the joints) and rheumatoid arthritis (arthritis caused by swelling of the lining of the joints) in patients who have a high risk of developing stomach ulcers. Diclofenac is in a class of medications called NSAIDs. It works by stopping the body's production of a substance that causes pain and inflammation. Misoprostol is in a class of medications called prostaglandins. It prevents ulcers caused by diclofenac by protecting the stomach lining and decreasing stomach acid production.
How should this medicine be used?
The combination of diclofenac and misoprostol comes as a tablet to take by mouth. It is usually taken with food two to four times a day. To help you remember to take diclofenac and misoprostol, take it at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take diclofenac and misoprostol combination exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the tablets whole; do not split, chew, or crush them. Do not take tablets that are broken or damaged.

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
