Seroquel Drug Interactions

When certain medications are taken with Seroquel, drug interactions may occur. Medicines that may have negative interactions include certain antibiotics or antifungals, lorazepam, and thioridazine. Seroquel drug interactions can decrease the effectiveness of both medications, increase the drug levels in your blood, or cause the drugs to lose their effectiveness, so your healthcare provider may adjust your dosages as necessary.
