Allergy warning

This drug can cause a severe allergic reaction. Symptoms can include:

  • trouble breathing
  • swelling of your face, tongue, eyes, or mouth
  • rash, itchy welts (hives), or blisters, alone or with fever or joint pain

If you have an allergic reaction, call your doctor or local poison control center right away. If your symptoms are severe, call 911 or go to the nearest emergency room.

Don’t take this drug again if you’ve ever had an allergic reaction to it. Taking it again could be fatal (cause death).

Alcohol interaction

You should avoid drinks that contain alcohol when taking this drug.

Warnings for people with certain health conditions

For people with glaucoma: Paroxetine may dilate your pupils, which may trigger a glaucoma attack. Notify your doctor if you have glaucoma before taking this drug.

For people with bipolar disorder: Caution should be used when taking this drug if you have bipolar disorder. Taking paroxetine alone may trigger a mixed or manic episode.

For people with seizures: Caution should be used when taking this drug if you have a history of seizures. If seizures occur while you take this drug, you should stop taking it and contact your doctor.

For people with kidney disease: If you have kidney disease, your kidneys may not be able to get rid of this drug as well as they should. This may cause levels of the drug to build up in your body and cause more side effects.

For people with liver disease: If you have liver disease, your body may not be able to process this drug as well as it should. This may increase the levels of this drug to build up in your body and cause more side effects.

Warnings for other groups

For pregnant women: The paroxetine brand-named drug Brisdelle is a category X drug. Category X drugs should never be used during pregnancy.

Women of childbearing age should use reliable birth control while taking this drug.

Paroxetine (except for the brand-named drug Brisdelle) is a category D pregnancy drug. That means two things:

  1. Research in humans has shown adverse effects to the fetus when the mother takes the drug.
  2. This drug should only be used during pregnancy in serious cases where it's needed to treat a dangerous condition in the mother.

Talk to your doctor if you’re pregnant or planning to become pregnant. Ask your doctor to tell you about the specific harm that may be done to the fetus. This drug should be only used if the potential risk to the fetus is acceptable given the drug’s potential benefit. Call your doctor right away if you become pregnant while taking this drug.

For women who are breastfeeding: This drug passes into breast milk and may cause side effects in a child who is breastfed. Caution should be used when taking this drug while breastfeeding. Talk to your doctor if you breastfeed your child. You may need to decide whether to stop breastfeeding or stop taking this medication.

For seniors: The kidneys of older adults may not work as well as they used to. This can cause your body to process drugs more slowly. As a result, more of a drug stays in your body for a longer time. This raises your risk of side effects.

If you’re over the age of 65 years, you may be at higher risk of developing side effects while taking this drug, including low sodium levels in your blood (known as hyponatremia).

For children: It hasn’t been confirmed that this drug is safe and effective for use in people younger than 18 years.
