Atogepant is available in tablet form and should be administered orally. Factors determining the dose and dosing regimen are individualized, based on the severity of the attacks and the presence of other medical conditions for which other drugs are being given, amongst others. Take only as prescribed by your health care provider. According to studies, generally, the dosing regimen in adults for atogepant is as follows:

 Initial dose: 60 mg once daily.

• Treatment: Based on how well the medicine is tolerated by the body, your doctor may increase the daily dose from the initial 30 mg to 60 mg. This dosage can increase up to 120 mg/day when necessary to optimize preventive effects for migraines.

Swallow the tablets with a glass of water, either with food or an empty stomach. Be careful to not crush or split the tablets.

Atogepant works by blocking the CGRP receptor, which is centrally involved in the pathophysiology of migraines. During a migraine attack, CGRP is released and promotes the dilation of blood vessels in the brain. Such dilation is believed to cause pain and other signs of a migraine. Atogepant reduces these neurochemical signals leading to vascular alterations and its associated pain due to the inability of CGRP to bind to its receptor.

Atogepant works by inhibiting the action of CGRP, thereby preventing the cascade of events that would lead to the manifestations of migraines. It is, therefore, a very useful drug for treatment in patients suffering from frequent or chronic migraines. As it does not treat acute symptoms, atogepant is administered for long-term preventive use in reducing the frequency of migraine attacks over time.

Overall, atogepant is tolerated well; however, like all drugs, it may also cause some side effects. These include:

1.Nausea: Some patients may experience mild to moderate nausea following the initiation of atogepant.

2. Constipation: This is very common and sometimes turn problematic.
3. Fatigue: Some patients claim to be more fatigued than usual on atogepant, especially at the initiation of the therapy.
4. Upper Respiratory Infections: Any medicine can trigger infections such as a cold or sinus infections in some cases.

For most patients, atogepant is safe; however, there are a few warnings and precautions that should be known beforehand before beginning treatment:

1.Allergic Reactions: Like with any drug, there is a possibility of a case of allergic reaction. 

2. Pregnancy and Breast-feeding There are no established studies of the use of atogepant in pregnant or breast-feeding women. Atogepant should be used with caution and under close supervision by your health care provider if you are pregnant, planning to become pregnant or breastfeeding.
3. Liver or kidney diseases: A patient with liver or kidney diseases should be under close monitoring by his doctor since the drug may affect liver or kidney functions. His dosage needs to be adjusted.

Avoid Certain Pain Relievers: Atogepant may interact with strong pain medications, like opioids, and cause unwanted side effects. Talk to your doctor if you’re using these.

Be Cautious with Blood Thinners: If you’re taking blood-thinning medications (like warfarin), Atogepant may increase bleeding risks. Your doctor may adjust your dosage.

Check for Liver Medications: Atogepant may interact with drugs that affect your liver. Let your doctor know if you are on medications for liver conditions.

Antidepressants and Anticonvulsants: Atogepant could interact with these types of medications, possibly affecting how they work. Always inform your doctor about all medicines you’re taking.

Recommended standard dose and dose adjustment

In adults, for the prevention of attacks, initiate at 60 mg orally once daily. Adjust the dosage based on your response to treatment, taking note that 30 mg orally daily could be effective in patients who are poor responders and possibly 120 mg orally daily may be needed for optimal effect.

Take atogepant as prescribed by your doctor. Missing the dose will decrease the effects of the drug on prevention of migraine attacks and therefore must be taken as directed. If a dose is missed, take that dose when you remember unless it is time for the next dose. Ignore the missed dose and continue your dosing schedule at regular time. DO NOT TAKE TWO DOSES AT ONCE to compensate for the missed dose.

Atogepant is a prescription drug; it can be administered only on prescription by a doctor. Your doctor will assess your medical history and conduct a proper evaluation of your symptoms and history of migraine for him to decide whether atogepant is the right treatment for you.
