Babies die after pregnant women given Viagra

The parents of around a dozen -babies in the trial - who are as yet unborn or in intensive care - now face a nervous wait.

The trial, which began in 2015, involved 11 hospitals and 183 women. Since the drug is no longer under patent, scientists have been keen to explore other uses for the drug.

"All participants were approached personally and nearly everyone was informed and knows by now whether they have taken the drug or the placebo". Six additional babies in the group had this lung disease but did not die.

In the roughly equal control group, just three babies had lung problems and none died.

Recent randomised clinical trials comparing the drug with a placebo had detected no adverse effects on healthy mothers or infants, giving the all clear for others to conduct further testing.

"We have already notified Canadian researchers who are conducting a similar study", Ganzevoort said. Researchers now believe that the Viagra caused high blood pressure in the babies' lungs, prohibiting them from receiving enough oxygen.

According to the Amsterdam UMC, of the 93 women treated with SIL in the clinical trial, 19 babies born to the 93 women treated with the drug died, 11 of them due to the lung disorder.

He may be the defending champion, but Froome will now be riding in service of Thomas for the rest of the Tour. Obviously on some of the climbs not everyone's our fans but we don't feel threatened", Thomas said.

The Queensland study was used over a significantly shorter time frame and for different reasons, but it had been paused as a precautionary measure while he gathered more information from the Dutch researchers, he added.

"We are using Sildenafil in women with full-term pregnancies who are appropriately grown". None of these babies had developed the lung disease.

"Foreign colleagues let slip that they sometimes prescribed it, with good results", says Ganzevoort, who was also careful to point out how doctors in the Netherlands are more cautious.

SIL, aka Viagra, is a drug approved by the Federal Drug Administration (FDA) and European Medicines Agency (EMA) for the treatment of erectile dysfunction and pulmonary hypertension in adults. A study by a team in the United Kingdom, published online in The Lancet Child & Adolescent Health in December 2017, found sildenafil didn't improve the duration of pregnancy, birth weight, or fetal and neonatal survival.

The trial has now been cancelled and an investigation is ongoing. That poses a hard dilemma for doctors: Inducing birth too early increases the risk of complications, but waiting too long could lead to developmental anomalies or stillbirth.

Previous studies in the U.K., Australia and New Zealand also examined whether sildenafil could assist these babies.
