Whether or not it is okay to take Polivir with a needle should depend on whether or not the patient is bleeding. The generic name of Polivir, clopidogrel, is an inhibitor of platelet aggregation. It is indicated for heart attack, atherosclerosis, thromboembolism and so on. Its adverse reactions include rash and bleeding. The drug is contraindicated in patients with severe liver impairment, with recent active bleeding or surgery. Polivir can also prolong bleeding, and should be used with caution in patients with wounds, such as the gastrointestinal tract and eyes, that bleed easily. If a patient has already had an adverse reaction to bleeding as a result of taking Polivir, it is best for the patient not to take the injection at this time or to do so under the guidance of a medical professional. If patients take Polivir without any bleeding symptoms, you can tie the needle.
