Telmisartan has been shown to cause some side effects. If these adverse reactions do not go away within a few days or become severe, talk to your health care provider.
Common side effects reported when taking telmisartan include:
- Back pain
- Sinus congestion
- Diarrhea
This is not a complete list of adverse effects – though these are the most common. Seek medical attention right away if you experience symptoms such as swelling, difficulty breathing, rash, weight gain, or hoarseness.
As with all prescription medication, be sure to inform the prescribing doctor about any medical conditions you have been previously diagnosed with and any medication/ supplements you are currently taking before starting treatment with telmisartan. Telmisartan can interact with other forms of medication and substances, causing potentially serious side effects. In addition, let your doctor know if you are currently breastfeeding. You should not breastfeed while taking telmisartan.
