2 What to Know Before Using

Before using Rogaine, you must know all about the risks and complications associated with it. The suitable drug therapy is usually chosen by a doctor with the active participation of the patient.

There are some important factors such as drug interactions, the presence of any metabolic impairment, history of hypersensitivity reaction, pregnancy, lactation etc. which may alter the desired therapeutic effects of a medicine.

Sometimes the presence of other health disorders affects the beneficial effects of this medicine and even may cause serious toxic effects. If you have had any allergic reactions to any medicine then you must tell your doctor about that.

The use of minoxidil is contraindicated in patients with a history of hypersensitive to this medicine or any of the other ingredients in the formulation such as propylene glycol or ethanol.

Make sure you inform your doctor if you have any other medical problems, especially:

  • Any other skin problems, an irritation, or a sunburn on the scalp—these conditions may cause too much topical minoxidil to be absorbed into the body and may increase the chance of side effects.
  • Heart disease 
  • Hypertension (high blood pressure)—topical minoxidil has not been studied in patients who have these conditions, but more serious problems may develop for these patients if they use more medicine than is recommended over a large area and too much minoxidil is absorbed into the body.

Because of drug-drug interactions, certain medicines should not be used along with this medicine. It is always recommended to consult with your doctor if you are in need of some other medications or even any over-the-counter medicine for another health problem in order to avoid unwanted toxic effects.

Besides, the following drug interactions should be kept in mind:

  • Absorption may be increased with corticosteroids, retinoid, and/or occlusive ointment bases.
  • Antihypertensive effect may be enhanced by other hypotensive drugs.
  • Severe orthostatic hypotension may occur with guanethidine.

Animal reproduction studies have shown an adverse effect, and there are no adequate and well-controlled studies in pregnant women. Thus, this drug should be used during pregnancy only if clearly needed.

Besides, caution should be exercised when used in lactating women because studies in women for determining infant risk suggest that this medication poses minimal risk to the infant when used during breastfeeding.
