Common Questions and Answers about Efavirenz cmax
sustiva
I have 20 years and I have HIV positive person. I drink medicines already 4 months. I use drugs Truvada and Efavirenz Teva. Please tell me how to code your disease treated? Whether you are at injection instead of pills?
Are there still any evidence of efavirenz teratogenicity in human studies especially on the neuro tube defect
6 hours. Maximal serum concentrations (Cmax) occur between 15 and 44 hours post dose, and are sustained for up to 48 to 72 hours. The Cmax and AUC measurements of PegIntron increase in a dose-related manner. After multiple dosing, there is an increase in bioavailability of PegIntron. Week 48mean trough concentrations (320 pg/mL; range: 0, 2960) are approximately 3-fold higher than Week 4 mean trough concentrations (94 pg/mL; range: 0, 416).
1 hours ago I had protected sex with a sex worker which ended with a failed condom(punched) and then hour later i went to consult doctor and he prescribed EFAVIRENZ and LAMZID.AM I STIL SAFE?
Since that time, he is receiving HAART with lamivudine-zidovudine-efavirenz twice daily, but he told me that there are some days ( at maximun 3) that he does not take the pills, but most days of the month he is adhering to the treatment. His current viral load is 39,000 copies/ml.
When I realized of him diagnosis, I went to a doctor who gave me profilaxis about 18 hours post-exposure with lamivudine-zidovudine.
You're fine.

How should I take Ribavirin tablets?
Take Ribavirin tablets exactly as your healthcare provider tells you. Your healthcare provider will tell you how many Ribavirin tablets to take and when to take it.
Take Ribavirin tablets with food.
However, more variability was observed in some of the pharmacokinetic parameters for bupropion (AUC, Cmax, and Tmax) and its active metabolites (t½) in patients with mild to moderate hepatic cirrhosis.
Pharmacokinetics
Maximal serum concentrations (Cmax) and AUC increased in a nonlinear dose related manner following administration of 90 to 270 mcg of Pegasys. Maximal serum concentrations (Cmax) occur between 72 to 96 hours post-dose.
I am an HIV + male. 43 on truvada/ efavirenz for 2 year with a count of minus 20(undetectable). I was penetrated twice last week where the condom broke and was NOT replaced. The "top" partner is aware of my hiv status. What are the chances of infection for him and apart from testing what should be done? I am otherwise very healthy, no cuts, blood or aparent bruising was detected. I am freaking out for him.
My doctor recently put me on a combination of drugs for PEP, the drugs are lamzid and efavirenz and have very serious side effects. My exposure was licking/sucking a nipple of a non-pregnant HIV positive person. No milk came or blood came out but just had an after taste in my mouth. The act was for 2-3 seconds. What are my chances of getting HIV and are the reported cases of infection in adults, cause I know with babies you can.
Hepatic Impairment
In a pharmacokinetic study of sixteen subjects with hepatic impairment (15 mild, 1 moderate per Child-Pugh score), both AUC and Cmax were approximately double the values seen in the healthy control group. Based on the findings, Cyclobenzaprine HCl should be used with caution in subjects with mild hepatic impairment starting with the 5 mg dose and titrating slowly upward.
Welcome to the forum. Thanks for your question.
Since you are under care with PEP drugs, that doctor or clinic really ought to be the primary source of information about your risk, follow-up plans, etc. Therefore, my comments are brief.
Based on HIV infected persons' sexual histories of when and how they were infected, a CDC study calculated a risk of 1 HIV infection for every 10,000 episodes or performing fellatio on infected partners.
m now under retro-viral treatment (Abacavir, 3TC Lamiduvina, and Efavirenz TM as known in my country), healthy, fit, high CD4 count, undetectable viral load. Recently, I met a person, we kissed and we practiced oral sex on each other. Eventhough I know my condition, and have always tried to avoid people practice fellation on me, he insisted and at the end I agreed. Now, I am really concerned about him. Could he have been infected? Should I tell him to test for HIV?
Hepatic Impairment
In volunteers with hepatic impairment (Child-Pugh Class A and B), sildenafil clearance was reduced, resulting in higher plasma exposure of sildenafil (47% for Cmax and 85% for AUC). The pharmacokinetics of sildenafil in patients with severely impaired hepatic function (Child-Pugh Class C) have not been studied. A starting dose of 25 mg should be considered in patients with any degree of hepatic impairment [see Dosage and Administration (2.5) and Clinical Pharmacology (12.3)].
Hi all,
I have been on a combination of PEP drugs for the past week, the drugs are lamzid and efavirenz. 2 days after taking the drugs I started growing ulcers on my mouth (which has happened before) and I think one in my anus. Could this mean that I am HIV positive? I am very scared. My exposure was sucking a nipple of a woman for less than 2 seconds.
On AUGUST 19TH and AUGUST 20TH, I started taking ARVs which doctor prescribed. (Tenofovir disoproxil fumarate 300mg, Lamivudine USP 600mg, Efavirenz USP 200mg). ARVs made me dizzy, so I stoppped on AUGUST 21ST and AUGUST 22ND. After the viral load result, I started ARVs again. One pill everyday regularly.
4. On AUGUST 29th, I gave blood sample for PCR-HIV QUALITATIVE: (Performed using the Roche COBAS Ampliprep/COBAS Taqman HIV-1 Qualitative Version 2.0 assay.) It turned out negative.
I was given pep (efavirenz+ tenofovir + lamivudine) for 28 days after 48 hours. But I had it for 29 days instead. Now after 57 days I am having flu like symptoms. Runny nose and a bit of sore throat. No fever though. And my abdominal hurts a bit and a little joint pain..
1. What are my chances of contracting hiv from this fingering exposure?
2. Is pep successful if taken at 48 hours of exposure.?
3. Do i need testing? I was tested negative at baseline.
They took my blood test only as a ground zero (for later comparisons). Then doctor prescribed me Zilarvir (2 tablets a day) and Efavirenz (1 tablet a day) to take them one (1) month. The medicines arrived at 15:00 (3:00 PM) and I took both - 17 hours after the incident and high risk exposure.
Doctor told me to come after one month when they will take a new blood test and follow-up.
I am on 300 mg of lamivudine (1 time before bed) 600 mg of efavirenz (1 time before bed) and 300 mg tenofovir (1 time before bed), How effective this for PEP? I am not sure coz I went for an emergency ward which may not have expert on HIV infection. Also I read the label it said for PEP purpouse lamivudine should be used as 150 mg twice daily. Am I right?
After 29 hours of exposure, I took Zifam Eletec (Tenofovir Disoproxil Fumarate 300mg+Lamivudine 300mg+Efavirenz 600mg) and I had been taking it regularly at the same exact time every day (30 days course) which ended on Jan 27, 2022.
1. For my case, may I know the HIV infection risk/possibility for my exposure (because the HIV status of that female is unknown and contact time is short)?
2.
For the pharmacologically active R(+) enantiomer of methadone, peak plasma concentration (Cmax) and systemic exposure (AUC) decreased by an average of 29%, while trough plasma concentration (Cmin) decreased by an average of 31%. For the S(-) enantiomer, the Cmax and AUC decreased by an average of approximately 35% and Cmin decreased by an average of 40%.
MANAGEMENT: Caution is advised if telaprevir is prescribed to patients treated with methadone.
