There is gross overuse of antibiotics in India. Some surveys suggest up to 50% of antibioitics are administered without clinical need. Cold and cough is invariably due to viral infections. Many bad throat cases are also viral in nature. Antibiotics are not needed in all these cases. Patients
get cured due to time factor and not due to medicines.
Augmentin (a combination of amoxycillin + clavulanic acid) is Category B-1 which is defined as drugs which have been taken by only a limited number of pregnant women without an increase in the frequency of malformations or other direct or indirect harmful effects on human foetus having been obsereved.
Amoxydar brand does not appear on the International Drug Data of reputed manufacturers. It appears to be containing amoxycillin. If so, its effect will be similar to Augmentin.
The administration of the above antibiotics is most unlikely to have any deleterious effect on the baby.
