Patients taking anticoagulants should report the following to their doctor: bleeding gums, blisters/bruises, and persistent headache that does not improve with pain relievers or NSAIDs. These signs and symptoms may indicate things like: the patient may be receiving too many blood thinners, or the patient may be taking aspirin along with blood thinners that the doctor probably didn't suggest. However, if the patient receives excessive amounts of anticoagulant, it is always important that antidotes for heparin such as protamine sulfate and warfarin such as: vitamin K are readily available. The priority is patient safety. Patients who are pregnant or may be breastfeeding are advised not to take anticoagulants because they increase the possibility of bleeding. If the patient may have other conditions such as: heart failure, congested heart failure, renal failure and liver dysfunction; should be reported to the doctor because the doctor may have to prescribe something that will be more effective to ensure that the patient receives the right medication and
