1. What Loniten is and what it is used for
2. What you need to know before taking Loniten
Do not take Loniten:
Warnings and precautions
Consult your doctor before starting to take Loniten if:
- you have any kidney problems, as your doctor may consider it necessary to reduce the dose of minoxidil and monitor the levels of water and salts in your body.
- you have liver problems, your doctor may start your treatment with a reduced dose once a day and gradually increase it until the effective dose is reached
- you have had a heart attack
Be careful with this medication if, during treatment, you notice that your limbs are swelling or you notice other signs of fluid retention. Minoxidil can cause your body to retain water and salts. To avoid this, your doctor will always instruct you to take Loniten along with another medication to lower blood pressure that promotes fluid elimination (diuretics). It is essential that you follow your doctor's instructions for taking this medication and their recommendations on a salt-free diet. They will also advise you to monitor your weight (an increase of 1 to 1.5 kg) to detect possible fluid retention, as the effect of Loniten may be reduced.
Consult your doctor if, during treatment, you notice that your heart is beating faster (tachycardia) or you experience pain or a feeling of pressure in your chest (angina pectoris). Minoxidil is usually administered along with another medication to lower blood pressure that prevents these symptoms.
During treatment, you may experience inflammation of the outer membrane that surrounds the heart (pericarditis) and/or fluid accumulation in the interior of that membrane (pericardial effusion) that can compress the heart (cardiac tamponade).
In most patients treated with minoxidil, excessive body hair growth (hypertrichosis) occurs. When treatment is discontinued, the appearance usually returns to normal within 1 to 6 months.
If you are going to undergo any diagnostic tests (including blood tests and electrocardiograms), inform your doctor that you are taking this medication, as it may alter the results.
Children
During treatment with minoxidil, the child must be under the supervision of specialists. The daily dose of minoxidil will be determined by the specialist and can be adjusted according to the child's needs. During treatment, the child will also be treated with other medications as decided by the specialist to prevent rapid heartbeats and fluid accumulation in the body. You should consult with the doctor if the child has any of the following symptoms: very rapid heartbeat, rapid breathing, swelling in the legs, rapid weight gain, and reduced urine output. During treatment with minoxidil, the child will need to be seen by the doctor regularly.
Use of Loniten with other medications
Inform your doctor or pharmacist if you are using, have recently used, or may need to use any other medication.
Especially, inform your doctor if you are taking other medications to lower blood pressure. The concurrent use of minoxidil with some blood pressure medications (such as guanethidine and betanidine) can cause an excessive drop in blood pressure.
Pregnancy, breastfeeding, and fertility
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication.

Excessive body hair growth (hypertrichosis) has been reported in newborns of mothers who took Loniten during pregnancy.
