Thanks. I'm on Tadalifil and tyvaso. I started getting a little heartburn. So that explains it.

Unfortunately, some medications used to treat PAH can cause heartburn. I've suffered from GERD for years. I take a prescription medication daily called pantoprazole. It is quite effective. However, when I was prescribed tadalafil I started noticing a bit of indigestion and heartburn sometimes after taking it. I've found a couple of TUMS usually relieve the symptoms.

Lifestyle changes may help reduce the frequency of acid reflux/heartburn to try:

*Maintain a healthy weight. Excess pounds put pressure on your abdomen, pushing up your stomach and causing acid to reflux into your esophagus.
*Stop smoking. Smoking decreases the lower esophageal sphincter's ability to function properly.
*Elevate the head of your bed. If you regularly experience heartburn while trying to sleep, place wood or cement blocks under the feet at the head end of your bed. Raise the head end by 6 to 9 inches. If you can't elevate your bed, you can insert a wedge between your mattress and box spring to elevate your body from the waist up. Raising your head with additional pillows isn't effective.
*Start on your left side. When you go to bed, start by lying on your left side to help make it less likely that you will have reflux.
*Don't lie down after a meal. Wait at least three hours after eating before lying down or going to bed.
*Eat food slowly and chew thoroughly. Put down your fork after every bite and pick it up again once you have chewed and swallowed that bite.
*Avoid foods and drinks that trigger reflux. Common triggers include alcohol, chocolate, caffeine, fatty foods or peppermint.
*Avoid tight-fitting clothing. Clothes that fit tightly around your waist put pressure on your abdomen and the lower esophageal sphincter.

If these measures on ineffective, you should consider talking with your physician about prescription medications.
