Drug Interaction Report

Using pregabalin together with telmisartan may cause angioedema, a condition associated with swelling of the face, eyes, lips, tongue, throat, and occasionally also the hands and feet. Each medication alone can also cause angioedema, but the risk may be increased when they are combined. Angioedema can occur with the first dose of medication or after many doses. You should discontinue the medications and seek immediate medical attention if you develop symptoms of angioedema or have difficulty swallowing or breathing. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

If you are taking telmisartan you should avoid potassium-containing salt substitutes or over-the-counter potassium supplements without first talking to your doctor. This can cause high levels of potassium in your blood. High levels of potassium can cause weakness, irregular heartbeat, confusion, tingling of the extremities, or feelings of heaviness in the legs. Call your doctor at once if you have any of these symptoms.

Alcohol can increase the nervous system side effects of pregabalin such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with pregabalin. Do not use more than the recommended dose of pregabalin, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.
