What is Vimovo?
Vimovo contains the active ingredient Naproxen, esomeprazole.
- Active ingredient — Naproxen, esomeprazole
- Registration number — 45/3.1/0179
- Registration holder — AstraZeneca Pharmaceuticals (Pty) Limited
It is approved for:
- Naproxen belongs to a group of medicines called “Non-Steroidal Anti- Inflammatory Drugs” (NSAIDs). It works by reducing inflammation
- Esomeprazole belongs to a group of medicines called “proton pump inhibitors”. It works by reducing the amount of acid your stomach produces. VIMOVO is used to treat inflammatory problems such as osteoarthritis, rheumatoid arthritis and ankylosing spondylitis in patients who need a “proton pump inhibitor” to reduce the risk of getting a stomach ulcer or an ulcer in the small intestine (gut) when treated with a Non-Steroidal Anti- Inflammatory Drug (NSAID)

Do not be concerned by this list of possible side effects. You may not get any of them. If any of the side effects gets serious, or if you notice any side effects not listed in this leaflet, please tell your doctor or pharmacist
Serious side effects and warning signs
This leaflet does not set out a separate list of serious side effects. The general warning signs below apply to any medicine.
General warning signs that apply to any medicine
Call for emergency help now if any of these happen
- Difficulty breathing, wheezing, or tightness in the throat or chest
- Swelling of the face, lips, tongue or throat
- A widespread rash with blistering or peeling skin, or sores in the mouth, eyes or genitals
- Fainting, collapse, or a sudden severe drop in alertness
- Chest pain, or sudden weakness or numbness on one side of the body
- A fit (seizure), or confusion that comes on suddenly
In South Africa call 10177 for an ambulance, or 112 from a mobile phone. Go to your nearest emergency department if it is faster. Do not wait to see whether the symptom settles.
How long can side effects last?
How long a side effect lasts depends on the effect, the product, how long it has been used, and the person. Some effects ease within days as the body adjusts. Others continue for as long as the product is used. A few can persist after stopping, and some need review rather than waiting.
- Settling effects — mild effects that ease over the first days or weeks of use
- Ongoing effects — effects that continue while the product is being used and improve after stopping
- Persistent effects — effects that continue after stopping and need medical review
- Delayed effects — effects that appear after weeks or months rather than immediately
Which of these applies to a particular effect is a clinical question. If a side effect is not settling, is getting worse, or is affecting your daily life, that is worth a conversation with a pharmacist or doctor regardless of how long it has been going on.
Evidence required before publish — source the following for Vimovo from the SAHPRA-approved patient information leaflet or professional information, and cite what you actually used.
- Anything the approved information for Vimovo says about how long specific effects last
- Whether the source describes any effect as usually temporary, or as needing review if it persists
- Whether any effect is described as continuing after the product is stopped
Factors that may affect side effects
The approved leaflet identifies the following cautions and factors.
Do not use it at all if
- If you are hypersensitive (allergic) to naproxen, esomeprazole or any of the other ingredients of VIMOVO (listed in section 6)
- If you are allergic to other proton pump inhibitor medicines
- If you are taking a medicine called “atazanavir” or “nelfinavir” (used to treat HIV)
- If aspirin, naproxen or other NSAIDS such as ibuprofen, diclofenac or COX-2 inhibitors have caused you to have asthma (wheeziness) or an allergic reaction such as itchiness or skin rash (urticaria)
- If you are in the last 3 months of pregnancy
- If you have severe problems with your liver, kidney or heart. Do not take VIMOVO if any of the above apply to you. If you are not sure, talk to your healthcare professional before taking VIMOVO. You must not take VIMOVO and must talk to your healthcare professional straight away, if any of the following happen to you before or while you are taking VIMOVO, as this medicine may hide the symptoms of other disease:
- You lose a lot of weight for no reason and have problems swallowing
- You start to vomit food or blood
- You pass black stools (blood-stained faeces)
Use with care, and tell your doctor, if
- You have inflammation of your intestines (Crohn’s disease or ulcerative colitis)
- You have any other problems with your liver or kidneys or if you are elderly
- You are taking other medicines such as corticosteroids taken by mouth, warfarin, Serotonin Selective Reuptake Inhibitors (SSRIs), aspirin or NSAIDs including COX-2 inhibitors. If any of the above apply to you (or you are not sure), talk to your healthcare professional before taking this medicine. VIMOVO may be associated with an increase in the risk of you having a heart attack (myocardial infarction) or stroke. The risk may happen early in treatment. Any risk is more likely with high doses and long lasting treatment. Do not exceed the recommended dose or length of treatment. Also, check with your doctor before taking VIMOVO if you have any heart problems, previous stroke or think you might be at risk of these problems. You may be at risk of getting these problems if:
- You have high blood pressure
- You have problems with your blood circulation or with your blood
- clotting
- You have diabetes
- You have high cholesterol
- You are a smoker. Some population studies have indicated that the use of a proton pump inhibitor (which is a component of VIMOVO) may be associated with a small increased risk for osteoporotic bone fractures (osteoporosis is a condition where certain bones become brittle). However, other similar population-based studies found no such increased risk. It has not been established that VIMOVO causes fractures. Please inform your doctor if you have been diagnosed with osteoporosis (brittle bone disease)
Pregnancy and breastfeeding
- • The safety of VIMOVO in pregnancy has not been established
- • Talk to you doctor before taking this medicine if you are planning to get pregnant
- • Do not breastfeed if you are taking VIMOVO
- This is because small amounts may pass into the mothers’ milk
- If you are planning to breast-feed you should not take VIMOVO
- If you are pregnant or breastfeeding your baby, please consult your doctor, pharmacist or other healthcare professional for advice before taking VIMOVO
Interactions and medicines to check
The approved leaflet names these interactions.
- A medicine called “atazanavir” or “nelfinavir” (used to treat HIV). Tell your doctor or pharmacist if you are taking any of the following medicines:
- Aspirin, other NSAID medicines (including COX-2 inhibitors)
- Ketoconazole, itraconazole or voriconazole (used to treat infections caused by a fungus)
- Cholestryamine (used to reduce cholesterol)
- Clarithromycin (used to treat infection)

- Cilostazol (used for pain in legs due to poor blood flow)
- Cyclosporin/Tacrolimus (used to prevent the immune system from attacking transplant organs). If any of the above apply to you (or if you are not sure), talk to your doctor or pharmacist before taking VIMOVO. VIMOVO with food and, drink and alcohol Do not take VIMOVO with food. This may reduce the effect of VIMOVO. Take your tablets at least 30 minutes before you have a meal
Bring the actual products to the conversation
A pharmacist can check for interactions much faster from the packaging than from remembered names.
What to do if you experience side effects
If you think you are having a side effect, the response depends on how severe it is. Use the warning signs above first — if any of those apply, treat it as urgent.
If the symptom is severe or frightening
Get medical help immediately. Call 10177 for an ambulance, or 112 from a mobile phone, or go to the nearest emergency department. Take the product and its packaging with you if you can.
If the symptom is mild but bothering you
- Write down what the symptom is, when it started, and how it relates to when you take the product
- Check the leaflet that came with the product to see whether the symptom is listed
- Speak to your pharmacist — for many questions this is the fastest route to a useful answer
- Contact the prescriber if the symptom is affecting your daily life or is not settling
Do not stop a prescribed treatment on your own
Stopping some treatments suddenly causes its own problems, and the condition being treated may get worse. If you want to stop, ask a pharmacist or doctor how to do it safely — they can usually offer an alternative.
You can also report a suspected side effect in South Africa. Reporting does not replace getting medical advice, and you do not need to be certain the product was the cause.
When to seek urgent medical help
Some symptoms need medical attention straight away rather than an appointment in a few days. Do not wait to see whether they settle.
Call for emergency help now if any of these happen
- Difficulty breathing, wheezing, or tightness in the throat or chest
- Swelling of the face, lips, tongue or throat
- A widespread rash with blistering or peeling skin, or sores in the mouth, eyes or genitals
- Fainting, collapse, or a sudden severe drop in alertness
- Chest pain, or sudden weakness or numbness on one side of the body
- A fit (seizure), or confusion that comes on suddenly
In South Africa call 10177 for an ambulance, or 112 from a mobile phone. Go to your nearest emergency department if it is faster. Do not wait to see whether the symptom settles.
Get same-day medical advice if you have
- A high fever, or a rash together with feeling generally unwell
- Yellowing of the eyes or skin, or unusually dark urine
- Unusual bruising or bleeding that you cannot explain
- Severe or persistent vomiting or diarrhoea, especially if you cannot keep fluids down
- A sudden change in mood, or thoughts of harming yourself
- Any symptom that is rapidly getting worse
If you are having thoughts of harming yourself
Help is available in South Africa. The SADAG helpline is 0800 567 567, or you can go to your nearest emergency department. You do not have to wait until it feels like an emergency.
How to report a suspected side effect in South Africa
South Africa has an official system for reporting suspected side effects, run by the South African Health Products Regulatory Authority (SAHPRA). Reports from the public and from healthcare professionals are how safety signals get detected after a product is already in use.
Who can report
Anyone can report — you do not have to be a healthcare professional, and you do not need to prove that the product caused the problem. A suspicion is enough. Patients, caregivers and family members can all submit a report.
What to have ready
- The name of the product, its strength and form, and the batch number if you have it
- Why it was being used, and when it was started and stopped
- What the suspected reaction was, when it began, and how long it lasted
- Any other medicines, supplements or remedies being used at the same time
- Basic details about the person affected — age and sex are usually enough
How to report
SAHPRA accepts adverse reaction reports through its e-Services reporting system and through the Med Safety mobile app. Healthcare professionals can also report through the same routes. Current forms and access points are published on the SAHPRA site.
- SAHPRA Health Products Vigilance — the main vigilance and reporting hub
- SAHPRA e-Services — current adverse reaction reporting access
Reporting is not a substitute for medical care
If someone is unwell now, get medical help first and report afterwards. Urgent symptoms always take precedence over paperwork.
