Basically, in an instalment loan, the borrower has to pay the entire debt on monthly instalment that is decided by the lender and borrower with a mutual discussion. However, if you think that your financial status is not good for a particular month and you will not be capable to pay the repayments, then you could approach your lender and discuss the issue. If there is a possibility, the lender might lower down your lower or even hold your instalments for a certain amount of time, but you could have to pay extra later and you might even charged an additional fee depending on the lender whom you are dealing.
