Medicines in Pregnancy. In pregnancy?

My wife is now 29 weeks pregnant. Doctor had recommended usual medicines of Iron, Folic Acid, Calcium etc. But 20 days back doctor has prescribed Alamin M Forte, but since it was not available that time locally, I took astymin M forte, which she is taking still. This medicine is a multivitamin which has certain Amino Acids, Namely, L Arginine, L Lysine HCL, DL Methionine,L leucine, L Valine, L Isoleucine, L Phenylalanine,L Tryptophan, L Threonine, L Histidine HCL plus certain vitamins and minerals in it. This medicines is recommended 2 times a day so my wife is taking this 2 times since last twenty days. Also doctor advised another tablet of multivitamin which has 10 mg of lycopene in it. It was suggested to take once a day. My wife is taking it since last 15 days. So my question is : whether amino acids which are mentioned above and lycopene (10 mg) are safe to take in pregnancy?
