###Human: Will taking Lonopin cause any complication in a pregnant HIV patient? ###Assistant: Hello. No, she should not stop low molecular weight injection and instead take a good brand either Enoxaparin or LMWX and tablet Ecosprin 150 mg, as her previous history is such that we should not ignore it. If not taken, then she is at high risk for early development of high BP, slow growth of the baby, water level around the baby remains low and some time bleeding can occur during pregnancy. So you have to be very careful.
