Razadyne ER and cardiologist

After taking Razadyne ER for two days my mother became dizzy, fell, and had speech impairment that put her in the hospital for 5 days. All the tests done came back fine, but because she had a pace maker and was only one baby aspirin she was given coumain. She also had an unexplained fever. The doctors made an educated guess (quote) that she had had a TIA and did not think the drug caused these symptoms. She is not on the drug now, but is now on other drugs that are causing her more problems. The ER doctor felt that it was the drug, but the neurologist and cardiologist did not think so.
