2046312 tn?1360379600 Coadministration with telaprevir may increase the plasma concentrations of drugs that are metabolized by CYP450 3A4. The mechanism is decreased clearance due to inhibition of CYP450 3A4 activity by telaprevir. MANAGEMENT: Caution is advised if telaprevir must be used concomitantly with medications that undergo metabolism by CYP450 3A4, particularly those with a narrow therapeutic range.
1476285 tn?1287337784 Coadministration with inhibitors of CYP450 3A4 may increase the plasma concentrations and pharmacologic effects of buprenorphine, which is partially metabolized (approximately 30%) by the isoenzyme. The interaction appears to be dependent, in part, on the route of administration of buprenorphine. When administered transdermally, buprenorphine peak plasma concentration (Cmax) and systemic exposure (AUC) were not significantly affected by ketoconazole, a potent CYP450 3A4 inhibitor.
Avatar m tn Nurse advised me to take ZIDOLAM-N as PEP for 28 days. After continuing for 3 days i visited a doctor and he told me that Nevirapine should not be used for PEP but since i already started the PEP, he advised me to continue the same medication and asked to monitor closely the side effects of the drug. Now today Friday i am experiencing some pain in the upper abdomen. Is there any possibility that i can change the PEP drug to avoid nevirapine, please Suggest?
Avatar m tn Theoretically, coadministration of drugs that are Beta-2 adrenergic agonists with other agents that can prolong the QT interval may result in additive effects, and result in ventricular arrythmias including torsade de pointes and sudden death. Generally speaking, combination of agents can often be unpredictable, depending on other coexisting risk factors. This does not necessarily mean this will happen to you. ALWAYS consult with your doctor or pharmacist to discuss your concerns.
Avatar m tn I am going to the US in 2 days, if I cannot find a way to get pep here, could I take his ARVs just until then as a temporary measure? He says he takes nevirapine and tenofivir/lamivudine blend. Any advice really appreciated! If my risk is very low I would prefer not to take pep but I suspect I may be best advised to do so. If it makes a difference, I am prone to have a tiny amount of blood(I think from tears) on toilet paper when I use the bathroom so that may make it more risky? Thanks!
547836 tn?1302832832 "Coadministration with an antacid containing magnesium, aluminum, and simethicone may decrease ribavirin AUC (clinical relevance unknown)" http://www.emedicine.com/derm/topic880.htm but it says "antacid containing magnesium, aluminum, and simethicone" and not just simethicone alone that may decrease riba absorption. Gas-X is not an antacid and simethicone is it's only active ingredient. does this make a difference at all?
Avatar f tn Sedation is a major side effect of tizanidine and may be potentiated by coadministration with other substances that have central nervous system-depressant effects or that may commonly cause drowsiness. MANAGEMENT: Use of tizanidine with other substances that commonly cause sedation should be approached with caution, particularly in elderly or debilitated patients.
Avatar f tn Coadministration with drugs that are inducers of CYP450 3A4 may decrease the plasma concentrations and efficacy of buprenorphine, which is metabolized in the liver by the isoenzyme. In addition, some of these inducers (anticonvulsants and barbiturates) may have additive central nervous system-depressant effects with buprenorphine.
Avatar m tn Tenofovir 300mg and Emtricitabine 200MG after 5hr from inccident early morning i meet another doctor he prescribe me TAB. Atazanavir 300mg and Ritonavir 100mg i get it after 24hr. After that i traked sex worker for blood sample after 30hr from inccident and tested for STD after a day i get her result that having HIV 1/2&P24 COMBO TEST INDEX VALUE 0.07, HERPES SIMPLEX VIRUS 1+2IgM SERUM 1.36, HERPES SIMPLEX 1+2 IgG SERUM 29.30,CHLAMYDIA TRACHMATIS POSITIVE, CHLAMYDIA PNEUMONAE POSITIVE.
2114467 tn?1358210256 Coadministration with the hepatitis C virus (HCV) NS3/4A protease inhibitors, boceprevir and telaprevir, may increase the systemic exposure to fluticasone following intranasal administration or oral inhalation. Boceprevir and telaprevir are potent inhibitors of CYP450 3A4. Since fluticasone undergoes extensive first-pass and systemic metabolism via hepatic and intestinal CYP450 3A4, inhibition of the isoenzyme may significantly increase systemic bioavailability of the drug.
Avatar m tn Coadministration with telaprevir may increase the plasma concentrations of systemic corticosteroids. The mechanism involves telaprevir inhibition of CYP450 3A4, the isoenzyme primarily responsible for the metabolic clearance of most steroids. No pharmacokinetic data are currently available, although telaprevir is a potent CYP450 3A4 inhibitor and may interact significantly. MANAGEMENT: The use of systemic corticosteroids in combination with telaprevir is not recommended.
Avatar m tn MONITOR! Coadministration with corticosteroids may decrease the serum concentrations and therapeutic effects of salicylates. Likewise, serum salicylate levels may increase following withdrawal of corticosteroid therapy, potentially resulting in salicylate toxicity. This interaction has been reported in patients receiving intra-articular as well as oral corticosteroids.
Avatar f tn Effect of Food on Absorption of Ribavirin Bioavailability of a single oral dose of Ribavirin was increased by coadministration with a high-fat meal. The absorption was slowed (Tmax was doubled) and the AUC0-192h and Cmax increased by 42% and 66%, respectively, when Ribavirin was taken with a high-fat meal compared with fasting conditions. Good luck with treatment.
Avatar m tn As I type this I am shaking in fear.. I really need your Professional advise on this. On Saturday morning last week I met a girl in Cambodia. After a few drinks together I took her back to my hotel & we had sex. I used a condom throughout the intercourse, however, after I ejaculated & pulled out I noticed the condom broke. It must have broke near the end as when we changed positions I noticed it was intact each time.
Avatar n tn Carboplatin allergies rarely have been reported and may be potentiated by coadministration of paclitaxel. Prolonged desensitization regimens are effective in the majority of patients with carboplatin hypersensitivity reactions. Alternatively, retreatment with cisplatin can be considered in the absence of cumulative cisplatin toxicity. and this is from: http://jco.ascopubs.
Avatar n tn He said that he is Undetectable for years now he also showed me his meds Truvada and Nevirapine... And I asked if he had Stds he said none because if he does have it. It would be detrimental to his health...

The absorption was slowed (Tmax was doubled) and the AUC0-192h and Cmax increased by 42% and 66%, respectively, when Ribavirin was taken with a high-fat meal compared with fasting conditions" Food slows down the absorption and keeps the riba in your system longer (a good thing).
3093770 tn?1389739126 Coadministration of naltrexone with other agents known to induce hepatotoxicity may potentiate the risk of liver injury. Naltrexone, especially in larger than recommended doses (more than 50 mg/day), has been associated with hepatocellular injury, hepatitis, and elevations in liver transaminases and bilirubin. MANAGEMENT: The use of naltrexone in combination with other potentially hepatotoxic agents (e.g.
