It is important to talk to your healthcare provider about the precautions and warnings with bromocriptine, as the medication can cause complications or worsen certain medical conditions. Bromocriptine has been reported to cause high or low blood pressure, heart attacks, and strokes. To help minimize risks, you should tell your healthcare provider about any existing conditions you have before starting the drug.

• High blood pressure (hypertension)
• Heart disease
• Low blood pressure (hypotension)
• Liver disease, such as liver failure, cirrhosis, or hepatitis
• Kidney disease, such as kidney failure (renal failure)
• Psychosis, such as schizophrenia
• Any allergies, including allergies to foods, dyes, or preservatives.
   

• Pregnant or thinking of becoming pregnant
• Breastfeeding.
   

• Bromocriptine has been reported to cause heart attacks, strokes, high blood pressure (hypertension), and low blood pressure (hypotension).
   
• At one point, bromocriptine was approved to suppress postpartum lactation (to suppress breast milk production after childbirth for women who will not be breastfeeding). However, bromocriptine is no longer approved for this use, since the benefits of bromocriptine are not worth the risk of serious side effects (such as strokes) for this use (see Parlodel and Breastfeeding).
   
• There have been some cases of lung problems in people who took bromocriptine. In general, these problems slowly improved after bromocriptine was stopped.
   
• It is not known whether bromocriptine is safe for people with liver or kidney disease.
   
• Bromocriptine can worsen psychosis and heart disease. If you have a history of such problems, bromocriptine may not be a good choice for you.
   
• Let your healthcare provider know if you develop blue, numb fingers or toes while taking bromocriptine. Your dosage may need to be reduced. Keeping your fingers and toes warm can help prevent this problem.
   
• Bromocriptine can cause hallucinations (seeing, hearing, or feeling things that are not really there) or other psychological problems. Let your healthcare provider know if you develop hallucinations while taking bromocriptine.
   
• Bromocriptine can potentially interact with several medications (see Drug Interactions With Bromocriptine).
   
• Bromocriptine is usually considered a pregnancy Category B medication. This means that it is probably safe for use during pregnancy, although the benefits may not outweigh the risks in many cases (see Parlodel and Pregnancy).
   
• Women should not take bromocriptine while breastfeeding. Therefore, if you are breastfeeding or plan to start, discuss this with your healthcare provider prior to taking the drug (see Parlodel and Breastfeeding).
