Your monthly Tybost cost savings if eligible

The Tybost patient assistance program can provide your medication for free. We simply charge $49 per month for each medication to cover the cost of our services. With NiceRx, you will only pay $49 to obtain your Tybost, regardless of the retail price.

Am I eligible for the Tybost patient assistance program?

To find out if you are eligible for Tybost assistance you can apply online using our enrollment application. Each pharmaceutical company sets its eligibility criteria, and we will review your application individually to determine if you may be eligible. The three main factors to consider are:

  • I am a permanent, legal resident of the United States or Puerto Rico
  • I am uninsured or my insurance doesn’t cover my medication
  • I meet certain income eligibility requirements

How do I apply for the Tybost patient assistance program?

Our application process aims to make it as easy as possible to apply for the Tybost patient assistance program. The first step is to complete our online enrollment application. We will ask you for details about your healthcare provider, your insurance plan, and your household income as this information is required by the pharmaceutical companies. We may be able to help you apply for other patient assistance programs too, so be sure to tell us about any medications you are taking as well as Tybost.

NiceRx will review your application and determine whether you may be eligible for Tybost assistance. If so, we will handle the full enrollment process for you and prepare all required documents for your healthcare provider to sign. Once you are successfully enrolled in the Tybost patient assistance program, we will help you manage your prescription refills by requesting refills on your behalf throughout your enrollment period. At the end of your enrollment period, we will contact you for updated information and seek to re-enroll you so you can continue to access affordable Tybost.

Is NiceRx a Tybost coupon provider?

NiceRx is a service provider that helps eligible individuals access the Tybost patient assistance program. We do not offer trial offers or free Tybost samples.

This will likely save you more money than if you were to use Tybost coupons, discount cards, or Tybost copay cards.

Can NiceRx help me get Tybost cheaper if I have insurance?

NiceRx may be able to help you if your insurance company will not pay for your Tybost medication. We may also be able to help if you have a high copay or coinsurance responsibility. Whether you have insurance or not, apply online using our enrollment application to find out more.

What is Tybost?

Tybost is an FDA (U.S. Food and Drug Administration) approved medication manufactured by Gilead Sciences, Inc. It is a CYP3A inhibitor indicated to increase the systemic exposure of atazanavir or darunavir in combination with other antiretroviral agents in the treatment of HIV infection for adults and adolescents from 12 years of age and over.

Tybost is not interchangeable with ritonavir to increase the systemic exposure of darunavir 600 mg twice daily, fosamprenavir, saquinavir, or tipranavir due to a lack of exposure data. Tybost is not recommended with darunavir 600 mg twice daily, fosamprenavir, saquinavir, or tipranavir. Tybost and ritonavir when given with either atazanavir or darunavir may result in different drug interactions than when used with concomitant medications.

What doses of Tybost are available?

Tybost is available in tablet form, in the following doses: 150 mg.

Always speak with your healthcare provider about any changes to your dose so they can monitor and evaluate your condition.
