Acetaminophen is a pain reliever and a fever reducer.

Aspirin is in a group of drugs called salicylates (sa-LIS-il-ATEs). It works by reducing substances in the body that cause pain, fever, and inflammation.

Caffeine is a central nervous system stimulant. It relaxes muscle contractions in blood vessels to improve blood flow.

Backaid IPF is a combination medicine used to treat pain caused by tension headaches, migraine headaches, muscle aches, menstrual cramps, arthritis, toothaches, the common cold, or nasal congestion.

Do not use aspirin for heart or blood vessel conditions unless your doctor tells you to.

Backaid IPF may also be used for purposes not listed in this medication guide.

Treatment of chronic HCV genotype 1 or genotype 3 infection in treatment-naive (previously untreated) or previously treated adults, including those with cirrhosis (compensated or decompensated), liver transplant recipients, and those with HIV coinfection.

Treatment of chronic HCV genotype 2 or genotype 4 infection; only limited data available.

Must be used in conjunction with other antivirals; do not use alone.

Usually used in a multiple-drug regimen that includes sofosbuvir (with or without ribavirin).

Efficacy of daclatasvir and sofosbuvir (with or without ribavirin) for treatment of HCV genotype 1a infection is reduced in cirrhotic patients with NS5A polymorphisms M28, Q30, L31, or Y93 at baseline. Consider screening for NS5A polymorphisms prior to initiation of treatment in cirrhotic patients with HCV genotype 1a infection. (See General under Dosage and Administration.)

Efficacy of daclatasvir and sofosbuvir (with or without ribavirin) is reduced in cirrhotic patients with HCV genotype 3 infection compared with those without cirrhosis.

Treatment of chronic HCV infection is complex and rapidly evolving; consult a specialist to obtain the most up-to-date information.
