Hypertension Home > Minoxidil Oral

Minoxidil oral is a prescribed medicine used for lowering blood pressure that is not adequately controlled with other medications and is causing damage to vital organs. It comes in the form of a tablet and is taken once or twice a day. Although most people tolerate the drug well, side effects may occur and can include headaches, nausea, and vomiting.

What Is Minoxidil Oral?

Minoxidil oral (Loniten®) is a prescription blood pressure medication approved to treat severe hypertension (high blood pressure). Because of the potential for serious side effects, minoxidil oral is only used to treat blood pressure that is damaging organs in the body and is not adequately controlled with other, safer blood pressure medications. It is used in combination with other blood pressure medications.
Minoxidil, the active ingredient, is also available in a liquid form (Rogaine®), which is applied topically to the scalp to promote hair growth. Minoxidil oral tablets should not be used in any way to stimulate hair growth. Making a liquid from minoxidil oral and using it on the scalp could result in too much of the medication being absorbed into the bloodstream, leading to dangerous side effects.

Are There Side Effects?

Just like any medicine, minoxidil oral can cause side effects. However, not everyone who takes the drug will experience problems. In fact, most people tolerate it quite well.
If reactions do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider. Serious reactions are less common.
Common side effects seen with minoxidil oral include but are not limited to:
  • Growth and darkening of fine body hair
  • Nausea
  • Vomiting
  • Headaches
  • Dizziness
  • Swelling or weight gain caused by fluid retention (edema).
