are there interactions between kaletra truvada and: 1.finasterid(propecia) 2.lamisil 3.viagra

Response from Dr. Young

Thanks for your post.

The only significant interaction between the medications that you've listed is beteween Kaletra (lopinavir/ritonavir) and Viagra. The ritonavir in Kaletra tends to increase the Viagra levels, hence the lowest effective dose of Viagra should be used. The combination should be avoided in certain at-risk patients, namely those with pulmonary hypertension.


afraid of starting meds
please help
