Vemlidy Precautions
Vemlidy can cause serious side effects, including:
- 1. Build-up of an acid in your blood (lactic acidosis). Lactic acidosis can happen in some people who take Vemlidy. Lactic acidosis is a serious medical emergency that can lead to death.
Lactic acidosis can be hard to identify early, because the symptoms could seem like symptoms of other health problems. Call your healthcare provider right away if you get the following symptoms which could be signs of lactic acidosis:- feeling very weak or tired
- have unusual (not normal) muscle pain
- have trouble breathing
- have stomach pain with
- nausea (feel sick to your stomach)
- vomiting
- feel cold, especially in your arms and legs
- feel dizzy or lightheaded
- have a fast or irregular heartbeat
- 2. Severe liver problems. Severe liver problems can happen in people who take Vemlidy. In some cases these liver problems can lead to death. Your liver may become large (hepatomegaly) and you may develop fat in your liver (steatosis) when you take Vemlidy.
Call your healthcare provider right away if you have any of the following symptoms of liver problems:- Your skin or the white part of your eyes turns yellow (jaundice).
- dark "tea-colored" urine
- light-colored bowel movements (stools)
- loss of appetite for several days or longer
- nausea
- stomach pain
You may be more likely to get lactic acidosis or severe liver problems if you are female, very overweight (obese), or have been taking Vemlidy for a long time.
- 3. Worsening of your Hepatitis B infection. Your hepatitis B Virus (HBV) infection may become worse (flare-up) if you take Viread and then stop it. A "flare-up" is when your HBV infection suddenly returns in a worse way than before.
-
- Do not let your Vemlidy run out. Refill your prescription or talk to your healthcare provider before your tenofovir is all gone.
- Do not stop taking Vemlidy without first talking to your healthcare provider.
- If you stop taking Vemlidy, your healthcare provider will need to check your health often and do blood tests regularly to check your HBV infection. Tell your healthcare provider about any new or unusual symptoms you may have after you stop taking Vemlidy.
- Talk to your doctor about taking an HIV test before starting treatment with Vemlidy for chronic hepatitis B. You should also get a test for HBV if you are taking tenofovir for treatment of HIV.
Other serious side effects of Vemlidy that can occur include:
- New or worse kidney problems can happen in some people who take Vemlidy. If you have had kidney problems in the past or need to take another medicine that can cause kidney problems, your healthcare provider may need to do blood tests to check your kidneys during your treatment with Vemlidy.
- Bone problems can happen in some people who take Vemlidy. Bone problems include bone pain, softening or thinning (which may lead to fractures). Your healthcare provider may need to do additional tests to check your bones.
- Changes in body fat can happen in some people who take antiviral medicines. These changes may include increased amount of fat in the upper back and neck ("buffalo hump"), breast, and around the main part of your body (trunk). Loss of fat from the legs, arms, and face may also happen. The cause and long-term health effects of these conditions are not known.
- Changes in your immune system (Immune Reconstitution Syndrome) can happen when you start taking HIV medicines. Your immune system may get stronger and begin to fight infections that have been hidden in your body for a long time. Tell your healthcare provider if you start having new symptoms after starting your HIV medicine.
