Here are five medications that cause weight gain, and steps you can take to maintain your body weight if you are taking any of these drugs.

1. Antidepressants

Serotonin reuptake inhibitors like Zoloft and Prozac are the most commonly prescribed antidepressants. SSRIs may be effective at elevating your mood, but act on the same brain receptors that affect your appetite. People who use SSRIs may experience increased cravings for unhealthy foods — especially those high in carbohydrates. Talk to your doctor about options for other antidepressants that are not known to cause weight gain, or about evidence-based non-drug treatments for depression.

2. Birth control

Bloating and water retention are common side effects of hormonal birth control pills and shots, which can affect your weight. Birth control medications also supply your body with more progesterone, which can drive your appetite and increase certain cravings. If you’re currently using birth control medications, consider switching to other methods, such as barrier methods or a hormone-free IUD.

3. Antihistamines

Regular use of over-the-counter and/or prescription antihistamines has been linked to weight gain.

If you suffer from allergies and use antihistamines on a regular basis, consider using other treatments that can relieve symptoms without causing weight gain, such as nasal spray for congestion.

If you’re taking beta blockers or angiotensin-receptor blockers to manage your heart health, start exercising regularly, get plenty of sleep, and focus on eating a healthy low-glycemic diet. These factors can help stave off any potential weight gain caused by these medications.

Then, find ways to avoid or manage those triggers so you can lower your likelihood of experiencing migraines. For instance, if you know that your migraines are related to , work on incorporating mindfulness techniques and other practices that can help lower your levels.
