The generic works without any side effects. Stop overpaying for these drugs. This durg is not covered by insurance due to the fact they are for cosmetic use. The generic hasn't been approved in the US due to the fact large pharma has been courting the FDA for years to limit generics. The generic is from Cipla, a reputable Indian drug manufacturer. I have been using the generic for over 3 years and wouldn't go back. Shipping does take about 1-2 weeks but for the price it is well worth the wait.
