I've been put on udiliv 300 recently to control my liver function and have been taking one dose each day after lunch for 10 days now. I've also been on ovral-l oral contraceptive for a few months for my ovarian cysts and also as a general contraceptive. Periods have been regular. Will these drugs interact with each other and reduce the efficiency of the other. I'm sexually active and my husband and I depend on the pills as condoms have a high failure rate.
