Malaria is spread by mosquitoes, which transmit the parasites that cause the infection, usually in tropical and subtropical parts of the world. Plaquenil drug monograph Plaquenil side effects dizziness Chloroquine is metabolized by the cytochrome P450 CYP enzymes CYP2C8, CYP3A4, and CYP2D6 Kim et al. 2003; Projean et al. 2003, with CYP2C8 contributing the most. As hydroxychloroquine and chloroquine differ in structure by only one hydroxyl group, it is very likely that hydroxychloroquine is also metabolized by the same enzymes. WebMD provides information about interactions between Plaquenil Oral and selected-cyp2d6-inhibitors-metoprolol. CYP2D6 inhibitors, such as hydroxychloroquine, could theoretically impair timolol metabolism; the clinical significance of such interactions is unknown. Brivaracetam Moderate Caution is warranted with the coadministration of hydroxychloroquine and antiepileptic drugs, such as brivaracetam. Hydroxychloroquine can lower the seizure threshold; therefore, the activity of antiepileptic drugs may be impaired with concomitant use. For example, it may be combined with an antibiotic to treat chronic Q-fever, which humans usually catch from farm animals or raw milk. Plaquenil is used to treat other types of infections too.

Antimalarial plaquenil1h chloroquine binding biochemistry and biophysicsWhat is the nursing intervention for hydroxychloroquine If hydroxychloroquine is discontinued, monitor the patient carefully and consider reducing the opioid dosage if appropriate. Codeine is primarily metabolized by CYP2D6 to morphine, and by CYP3A4 to norcodeine; norcodeine does not have analgesic properties. Hydroxychloroquine is a moderate inhibitor of CYP2D6.

Plaquenil is prescribed for the treatment or prevention of malaria. It is also prescribed for the treatment of rheumatoid arthritis, lupus, and the side effects of lupus such as hair loss, joint pain, and more. Side effects, drug interactions, pregnancy safety information, and dosage information should be reviewed prior to taking this medication. For tamoxifen to do its job, it needs to be broken down in the body by a key protein known as CYP2D6. Unfortunately, many common medicines can block or slow down CYP2D6, and that would make tamoxifen less effective. Certain medications used to treat depression should be avoided by women taking tamoxifen.
