Children and adolescents

There is no experience with the use of pentoxifylline in children.

Using Pentoxifylline Vir with other medications

Tell your doctor or pharmacist if you are taking, have recently taken, or may take any other medication.

If pentoxifylline and antihypertensive medications are administered simultaneously, it may be necessary to adjust the dose individually; therefore, you should inform your doctor if you are taking any medication for high blood pressure.

Treatment with pentoxifylline in patients treated with diabetes medications (insulin or oral treatment) may enhance the effect of these medications, so you should inform your doctor if you are taking any medication for diabetes.

Similarly, simultaneous treatment with pentoxifylline and theophylline may cause an increase in theophylline levels, thereby increasing its side effects; therefore, it is necessary to inform your doctor if you are taking any medication containing theophylline.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication.

Pentoxifylline is not recommended during pregnancy.

Since pentoxifylline passes into breast milk in small amounts, your doctor will assess the convenience of continuing or not continuing treatment during breastfeeding.

Driving and using machines

No negative effects of pentoxifylline on the ability to drive vehicles or operate machinery have been reported.

Pentoxifylline Vir contains lactose

If your doctor has told you that you have an intolerance to certain sugars, consult with them before taking this medication.

3. How to take Pentoxifylline Vir

Follow the administration instructions for this medication exactly as indicated by your doctor or pharmacist, regarding the number of tablets to take and how often, as the dose is guided by the nature and severity of the disease, as well as the patient's tolerance. In case of doubt, ask your doctor or pharmacist.

It is essential to inform your doctor about any illness you may have, as this may be useful in determining the correct dose for you.

The recommended dose is one tablet, two or three times a day, which should be taken whole with some liquid, after meals.

If you have severe kidney or liver disease, your doctor will reduce the dose, adjusting it according to the disease and your tolerance to the medication.

If you have low or unstable blood pressure, or suffer from a disease that could be worsened by a decrease in blood pressure (severe coronary heart disease or stenosis of the blood vessels that supply the brain), your doctor will prescribe a low initial dose that will be gradually increased, according to the observed response.

The tablets should be taken whole, with a little water, after meals.

If you take more Pentoxifylline Vir than you should

If you take a dose of pentoxifylline that is too high, you may experience nausea, dizziness, palpitations, or a sudden drop in blood pressure. Additionally, fever, agitation, hot flashes, loss of reflexes, convulsions, skin rashes, coffee-ground vomiting, and loss of consciousness may occur. If you observe these symptoms, go to your doctor or the emergency department of the nearest hospital, bringing this package leaflet with you. Or, if you realize you have taken more doses than prescribed, call your doctor immediately, who will indicate the measures to take.

In case of overdose or accidental ingestion, consult the Toxicology Information Service, phone 91 562 04 20, indicating the medication and the amount ingested.
