Warnings and precautions
Consult your doctor or pharmacist before starting to use this medicine.
You should avoid using Inacid with other NSAIDs, including other anti-inflammatory medicines such as selective cyclo-oxygenase-2 (COX-2) inhibitors.
Tell your doctor if you suffer or have suffered from any of the following conditions:
Tell your doctor
Gastrointestinal risks:
The most frequent adverse effects that occur with medications like Inacid are gastrointestinal: peptic ulcers, gastrointestinal bleeding, perforations (in some cases fatal), especially in elderly people. Less frequently, gastritis has been observed. These can occur at any time during treatment with or without prior warning.
The risk of gastrointestinal bleeding is higher when high doses are used if you have a history of peptic ulcers or are elderly. In these cases, your doctor will consider the possibility of associating a stomach protective medication.
If you experience abdominal pain, vomiting blood or dark material that looks like coffee grounds, or black stools, these can be symptoms of gastrointestinal bleeding.
Stop using Inacid and seek medical help immediately.
Cardiovascular risks:
Medications like Inacid may be associated with a moderate increase in the risk of suffering a heart attack (myocardial infarction) or stroke. This risk is more likely to occur when high doses are used and treatments are prolonged. Your doctor may monitor your blood pressure as Inacid can cause it to increase.
It is important that you take the lowest dose of Inacid that relieves/controls your symptoms for the minimum necessary time.
If you have heart problems, have had a heart attack, a history of strokes, or think you may be at risk for these conditions (for example, you have high blood pressure, suffer from diabetes, have high cholesterol, or are a smoker), you should discuss this treatment with your doctor.
Risk of severe skin reactions:
Medications like Inacid may be associated, in very rare cases, with severe skin reactions such as Stevens-Johnson syndrome and toxic epidermal necrolysis.
The highest risk of suffering these reactions is at the beginning of treatment (usually within the first month of treatment). If you experience skin rashes, possibly with blistering or mucosal ulcers (e.g., in the mouth), or other symptoms of an allergic reaction, stop taking Inacid and consult your doctor immediately.
Risk of liver reactions:
Medications like Inacid may be associated with liver disorders that cause yellowing of the skin and eyes, sometimes with high fever or swelling and sensitivity of the upper abdomen.
Vision:
If you have blurred vision while using Inacid, stop using Inacid and inform your doctor.
Other precautions:
Tell your doctor if you have headaches, possibly with dizziness and drowsiness after using Inacid.
In some cases, Inacid can worsen psychiatric disorders, epilepsy, and Parkinson's disease. Therefore, if you suffer from any of these disorders and notice a worsening, you should discuss this treatment with your doctor.
Like other non-steroidal anti-inflammatory drugs, Inacid can mask the symptoms of an infection.
Your doctor may indicate the need for blood tests during treatment with Inacid to monitor your blood cells, liver function, kidney function, or blood levels of other medications.
In the case of suppositories, you may occasionally experience the sensation of needing to defecate and irritation of the rectal mucosa.
Children and adolescents
Do not administer in children under 14 years old.
Using Inacid with other medicines
Tell your doctor or pharmacist if you are using or have recently used or might use any other medicines.
Certain medicines may interact with Inacid. In these cases, it may be necessary to change the dose or interrupt treatment with one of the other medicines.
This is especially important if you are using:
Pregnancy, breastfeeding, and fertility
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor for advice before taking this medicine.
Do not take Inacid if you are in the last 3 months of pregnancy, as it may harm your baby or cause problems during delivery. It can cause kidney and heart problems in your baby. It can affect your tendency and that of your baby to bleed and delay or prolong delivery more than expected. You should not take Inacid during the first 6 months of pregnancy unless it is clearly necessary and as your doctor indicates. If you need treatment during this period or while trying to become pregnant, you will take the minimum dose for the shortest possible time. If you take it for more than a few days from the 20th week of pregnancy, Inacid can cause kidney problems in your baby, which can lead to low levels of amniotic fluid surrounding the baby (oligohydramnios) or narrowing of a blood vessel (ductus arteriosus) in the baby's heart. If you need treatment for more than a few days, your doctor may recommend additional checks.
Because the administration of medications like Inacid has been associated with a higher risk of congenital anomalies/spontaneous abortions, its administration is not recommended during the first and second trimester of pregnancy, unless it is strictly necessary. In these cases, the dose and duration of treatment will be limited to the minimum possible.
Breastfeeding
Indomethacin is secreted in breast milk, therefore, you should not take this medicine if you are breastfeeding.
Fertility
Inacid may decrease your ability to conceive. Inform your doctor if you are planning to have a baby or if you have any problems becoming pregnant.
Driving and using machines
Inacid can cause drowsiness, dizziness, and blurred vision. In these cases, do not drive or use any tool or machinery that requires you to be alert.
