Cluster headaches are an especially painful form of headache that were hard to treat until a drug called Verapamil came on the market. But Verapamil isn't the wonder drug it seems -- it's been linked to cardiac irregularity, and according to studies, one in five patients recieving high doses of Verapamil will develop cardiac irregularities -- very frightening indeed!Verapamil is fairly new, as is this bit of news, so it hasn't been removed from the market. Therefore, it's important to weigh the risks and talk to your doctor before going on any new drug.
