Summary
dolutegravir/lamivudine

Dovato is a complete HIV-1 treatment that combines two medicines into one tablet. It is used for adults and adolescents who weigh at least 55 pounds.

sucralfate

Sucralfate is a medicine that helps heal and protect ulcers in your small intestine. It creates a coating over the ulcer to shield it from stomach acid.

What It Treats
dolutegravir/lamivudine

Dovato is used to treat HIV-1 infection in adults and adolescents (12 years and older, weighing at least 55 pounds). It can be used if you have never taken HIV-1 medicines before. It can also be used to replace your current HIV-1 medicines if your virus is under control (HIV-1 RNA less than 50 copies/mL) and you have not had treatment failure or resistance to the medicines in Dovato.

sucralfate

Sucralfate is used to treat active duodenal ulcers, which are sores in the first part of your small intestine. It can help heal these ulcers over a period of 4 to 8 weeks. Sucralfate can also be used as maintenance therapy at a lower dose to prevent ulcers from coming back after they have healed.

How It Works
dolutegravir/lamivudine

Dovato contains two drugs: dolutegravir and lamivudine. Dolutegravir blocks HIV-1 integrase, an enzyme the virus needs to multiply. Lamivudine blocks reverse transcriptase, another enzyme HIV-1 needs to make copies of itself.

sucralfate

Sucralfate works by forming a protective layer over the ulcer. This coating acts like a bandage, shielding the ulcer from stomach acid and enzymes. This protection helps the ulcer heal.

Serious Warnings
dolutegravir/lamivudine

If you have both HIV-1 and hepatitis B, you should be tested for hepatitis B before starting Dovato. Using Dovato can cause the hepatitis B virus to become resistant to lamivudine. Stopping Dovato can also cause a severe worsening of hepatitis B. Your liver function should be checked regularly.

sucralfate

Inadvertent injection of sucralfate has led to fatal complications, including blood clots in the lungs and brain. Sucralfate is not intended for intravenous administration.

Pregnancy
dolutegravir/lamivudine

There is a pregnancy registry to monitor outcomes in people exposed to Dovato during pregnancy. Talk to your doctor if you are pregnant or plan to become pregnant. There may be a risk of neural tube defects if dolutegravir is taken at the time of conception.

sucralfate

It is not known if sucralfate can harm an unborn baby. Talk to your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

For these top-ranked reactions alone, dolutegravir/lamivudine has 5,167 submissions while sucralfate has 8,557.
